CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

The United States Securities and Exchange Commission (the “Commission”) defines “disclosure controls and procedures” as controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms.

After evaluating the effectiveness of Canadian National Railway Company’s disclosure controls and procedures as of the end of the fiscal year covered by this report, Canadian National Railway Company’s President and Chief Executive Officer (the “CEO”) and its Executive Vice President and Chief Financial Officer (the “CFO”) have concluded that Canadian National Railway Company’s disclosure controls and procedures were effective as of the end of the fiscal year covered by this report.

ITEM 2 INCORPORATION

2.1 INCORPORATION OF THE ISSUER

CN was incorporated in 1919 by special act of the Parliament of Canada with the appointment of its first Board of Directors by Order in Council in 1922. CN’s continuance under the Canada Business Corporations Act was authorized by the CN Commercialization Act and was effected by Certificate of Continuance dated August 24, 1995. On November 9, 1995, CN filed Articles of Amendment in order to subdivide its outstanding common shares (Common Shares). As of November 28, 1995, CN ceased to be a Crown corporation and became a publicly held corporation with its Common Shares listed on the New York Stock Exchange (NYSE) and the Toronto Stock Exchange (TSX). On April 19, 2002, CN filed Articles of Amendment in order to provide that shareholder meetings may be held at certain specified places in the U.S. Such constating documents are hereinafter collectively referred to as the Articles.

CN’s Articles provide that the head office of the Company shall be situated in the Montreal Urban Community, province of Quebec, Canada. The Company’s registered and head office is located at 935 de La Gauchetière Street West, Montreal, Quebec, H3B 2M9, Canada, and its telephone number is 1-888-888-5909.

ITEM 3 GENERAL DEVELOPMENT OF THE BUSINESS

3.1 GENERAL DEVELOPMENT OF THE BUSINESS DURING THE LAST THREE YEARS

A clear strategic agenda, driven by a commitment to innovation, productivity, supply-chain collaboration, running trains safely, and minimizing environmental impact, drive the Company’s efforts to create value for

Table of Contents

2016 Annual Information Form

customers. CN thereby creates value for its shareholders by striving for sustainable financial performance through profitable top-line growth, adequate free cash flow and return on invested capital. CN is also focused on returning value to shareholders through dividend payments and share repurchase programs.

The initiatives undertaken by CN in the last three years to achieve its growth and profitability goals and to enhance shareholder value can be grouped into a few key areas. These include acquisitions and dispositions, targeted capital investment spending and other initiatives to strengthen the Company’s position in the marketplace, as well as financial management initiatives, as described below.

2016 Highlights

Leadership Changes

On June 7, 2016, CN announced a number of leadership changes including Claude Mongeau’s decision, due to a health condition, to step down from his role as President and Chief Executive Officer (CEO) and member of the Board of Directors at the end of June 2016, as well as the appointment of Executive Vice-President and Chief Financial Officer (CFO) Luc Jobin to President and CEO on July 1, 2016 and a member of the Board of Directors on June 30, 2016. Additionally, on June 27, 2016, the Company announced that Ghislain Houle would become Executive Vice-President and CFO, and that Mike Cory would assume the role of Executive Vice-President and Chief Operating Officer, following the retirement of Jim Vena, effective July 1, 2016.

Strategic Initiatives and Capital Spending

CN’s business strategy is anchored on the continuous pursuit of Operational and Service Excellence, an unwavering commitment to safety and sustainability, and the development of a solid team of motivated and competent railroaders. CN’s success and long-term economic viability depends on the presence of a supportive regulatory and policy environment that drives investment and innovation. CN’s success also depends on a stream of capital investments that supports its business strategy. These investments cover a wide range of areas, from track infrastructure and rolling stock, to information and operating technologies, and other equipment and assets that improve the safety, efficiency and reliability of CN’s service offering. Investments in track infrastructure enhance the productivity and integrity of the plant, and increase the capacity and the fluidity of the network. The acquisition of new locomotives and railcars generates several key benefits. New locomotives increase fuel productivity and efficiency, and improve the reliability of service. Locomotives equipped with distributed power allow for greater productivity of trains, particularly in cold weather, while improving train handling and safety. Targeted railcar acquisitions aim to tap growth opportunities, complementing the fleet of privately owned railcars that traverse CN’s network. CN’s strategic investments in information technology provide access to timely and accurate information which supports CN’s ongoing efforts to drive innovation and efficiency in service, cost control, asset utilization, safety and employee engagement.

CN is committed to the safety of its employees, the communities in which it operates and the environment. Safety consciousness permeates every aspect of CN’s operations. The Company’s long-term safety improvement is driven by continued significant investments in infrastructure, rigorous safety processes and a focus on employee training and safety awareness. CN continues to strengthen its safety culture by investing significantly in training, coaching, recognition and employee involvement initiatives.

CN spent $2.75 billion in its capital program, with $1.6 billion invested to maintain the safety and integrity of the network, particularly track infrastructure; $0.55 billion for equipment capital expenditures, including 90 new high-horsepower locomotives, $0.3 billion on initiatives to support growth and drive productivity, and $0.3 billion for the U.S. federal government legislative Positive Train Control (PTC) implementation.

2016 Annual Information Form

Acquisitions and Dispositions

On December 1, 2016, the Company completed the sale of approximately one mile of elevated track leading into Montreal’s Central Station, together with the rail fixtures, to CDPQ Infra Inc., a wholly owned subsidiary of the Caisse de dépôt et placement du Québec, for cash proceeds of $85 million before transaction costs. The transaction resulted in a gain on disposal of $76 million ($66 million after-tax) that was recorded in Other income under the full accrual method of accounting for real estate transactions.

Financial Management Initiatives

On January 5, 2016, CN filed a new shelf prospectus with the Canadian securities regulators and a registration statement with the U.S. Securities and Exchange Commission (SEC) pursuant to which CN may issue up to $6.0 billion of debt securities in the Canadian and U.S. markets. The shelf prospectus and registration statement expire on February 4, 2018 and replace CN’s previous shelf prospectus and registration statement. Access to capital markets under the shelf prospectus and registration statement is dependent on market conditions at the time of pricing.

The Company has a commercial paper program in Canada and in the U.S. Both programs are backstopped by the Company’s revolving credit facility, enabling it to issue commercial paper up to a maximum aggregate principal amount of $1.3 billion, or the U.S. dollar equivalent, on a combined basis, which was increased from $800 million, effective May 5, 2016. As at December 31, 2016, the Company had total commercial paper borrowings of $605 million (U.S. $451 million). The commercial paper programs, which are subject to market rates in effect at the time of financing, provide the Company with a flexible financing alternative at a low cost, and can be used for general corporate purposes. The weighted-average interest rate on these borrowings was 0.65%.

The Company has an agreement to sell an undivided co-ownership interest in a revolving pool of accounts receivable to unrelated trusts for maximum cash proceeds of $450 million. On October 25, 2016, the Company extended the term of its agreement by one year to February 1, 2019. As at December 31, 2016, the Company had no proceeds received under the accounts receivable securitization program. The accounts receivable securitization program provides the Company with readily available short-term financing for general corporate use.

The Company has an unsecured revolving credit facility with a consortium of lenders. On March 11, 2016, the credit facility agreement was amended, which increased the credit facility from $800 million to $1.3 billion, effective May 5, 2016, consisting of a tranche for $420 million maturing on May 5, 2019 and a tranche for $880 million maturing on May 5, 2021. The increased capacity provides the Company with additional financial flexibility. The credit facility agreement allows for an increase in the credit facility amount, up to a maximum of $1.8 billion, as well as the option to extend the term by an additional year at each anniversary date, subject to the consent of individual lenders. The credit facility provides for borrowings at various interest rates, including the Canadian prime rate, bankers’ acceptance rates, the U.S. federal funds effective rate and the London Interbank Offered Rate (LIBOR), plus applicable margins, based on CN’s debt credit ratings. The credit facility is available for working capital and general corporate purposes, including backstopping the Company’s commercial paper programs. The credit facility agreement has one financial covenant, which limits debt as a percentage of total capitalization, and with which the Company is in compliance. As at December 31, 2016, the Company had no outstanding borrowings under its revolving credit facility and there were no draws during the year ended December 31, 2016.

The Company has a series of committed bilateral letter of credit facility agreements. During 2016, the Company extended the expiry date of the majority of these agreements by one year to April 28, 2019, and entered into various uncommitted bilateral letter of credit facility agreements. These agreements are held with various banks to support the Company’s requirements to post letters of credit in the ordinary course of business. Under these agreements, the Company has the option from time to time to pledge collateral in the form of cash or cash equivalents, for a minimum term of one month, equal to at least the face value of the letters of credit issued. As at December 31, 2016, the

Table of Contents

2016 Annual Information Form

Company had outstanding letters of credit of $451 million under the committed facilities from a total available amount of $508 million and $68 million under the uncommitted facilities. As at December 31, 2016, included in Restricted cash and cash equivalents was $426 million and $68 million which were pledged as collateral under the committed and uncommitted bilateral letter of credit facilities, respectively.

On August 2, 2016, under its shelf prospectus and registration statement, the Company issued US$650 million ($848 million) 3.20% Notes due 2046 in the U.S. capital markets, which resulted in net proceeds of $832 million and on February 23, 2016, under its shelf prospectus and registration statement, the Company issued US$500 million ($686 million) 2.75% Notes due 2026 in the U.S. capital markets, which resulted in net proceeds of $677 million. The proceeds from both debt issuances were used for general corporate purposes, including the redemption and refinancing of outstanding indebtedness, and share repurchases.

On October 25, 2016, the Board of Directors approved a new share repurchase program which allows for the repurchase of up to 33.0 million Common Shares, between October 30, 2016 and October 29, 2017, pursuant to a normal course issuer bid at prevailing market prices plus brokerage fees, or such other prices as may be permitted by the TSX. On November 2, 2016 and on December 13, 2016, the Company announced that it entered into agreements with third parties to repurchase Common Shares through daily purchases subject to a maximum of 2,723,662 Common Shares and 4,840,000 Common Shares, respectively. Purchases pursuant to the agreements took place from November 7, 2016 to December 30, 2016 and will be completed by March 15, 2017. Pursuant to the terms of the agreements, and subject to the terms of issuer bid exemption orders issued by the Ontario Securities Commission (“OSC”), the third parties purchased CN’s Common Shares on the open market for their own account in accordance with the rules applicable to the normal course issuer bid, for the purpose of ultimately fulfilling their delivery obligations to CN under the agreements. The price that CN paid for Common Shares purchased by it from the third parties under the agreements was negotiated by CN and the third parties and was at a discount to the prevailing market price of CN’s Common Shares on the TSX at the time of the purchase. The purchases formed part of CN’s repurchase of up to 33.0 million Common Shares under its October 25, 2016 share repurchase program.

On February 5, February 19, March 16 and July 29, 2016, the Company announced that it entered into agreements with third parties to repurchase Common Shares through daily purchases subject to an aggregate maximum of 21.895 million Common Shares. The purchases took place from February 12, 2016 to October 29, 2016. Pursuant to the terms of the agreements, and subject to the terms of issuer bid exemption orders issued by the OSC, the third parties purchased CN’s Common Shares on the open market for their own account in accordance with the rules applicable to the normal course issuer bid, for the purpose of ultimately fulfilling their delivery obligations to CN under the agreements. The price that CN paid for Common Shares purchased by it from the third parties under the agreements was negotiated by CN and the third parties and was at a discount to the prevailing market price of CN’s Common Shares on the TSX at the time of the purchase. All the purchases formed part of CN’s then current share repurchase program.

Significant Collective Agreements

Canadian workforce

On March 23, 2016, the Company served notice to commence bargaining for the renewal of the collective agreements with the Teamsters Canada Rail Conference (TCRC) governing approximately 2,500 train conductors and yard coordinators, which expired on July 22, 2016. On June 29, 2016, the Company filed a notice of dispute seeking conciliation assistance. On July 14, 2016, the Minister of Labour appointed two conciliation officers to assist the parties with their negotiations. On September 16, 2016, the Company and the TCRC agreed to extend the conciliation period on a voluntary basis.

On October 12, 2016, the Company served notice to commence bargaining for the renewal of the collective agreement with the International Brotherhood of Electrical Workers (IBEW) governing approximately 700 signals and

Table of Contents

2016 Annual Information Form

communications workers, which expired on December 31, 2016. On December 15, 2016, CN filed a notice of dispute seeking conciliation assistance with the Minister of Labour. On December 29, 2016, the Minister of Labour appointed two conciliation officers to assist the parties in their efforts to renew the collective agreement.

Under the Canada Labour Code, the law governing labor relations for the Canadian railroad industry, collective agreements remain in force until such time as the parties have either reached a renewed agreement or the dispute resolution mechanisms in the Code have been exhausted.

U.S. workforce

As of February 1, 2017, the Company had in place agreements with bargaining units representing the entire unionized workforce at Grand Trunk Western Railroad Company (GTW), companies owned by Illinois Central Corporation (ICC), companies owned by Wisconsin Central Ltd. (WC), Bessemer & Lake Erie Railroad Company (BLE) and The Pittsburgh and Conneaut Dock Company (PCD). Agreements in place have various moratorium provisions up to 2018, which preserve the status quo in respect of the given collective agreement during the terms of such moratoriums. All collective agreements covering non-operating craft employees and six collective agreements covering roughly half of the operating craft population of 3,000 employees are currently under renegotiation.

During 2016, the Company renewed four collective agreements with the United Transportation Union (a division of the International Association of Sheet Metal, Air, Rail, and Transportation Workers - SMART) governing 65 yardmasters at GTW, two WC bargaining units and a small subset working on the ICC.

The general approach to labor negotiations by U.S. Class I railroads is to bargain on a collective national basis with the industry, which GTW, ICC, WC and BLE have agreed to participate in, for collective agreements covering non-operating employees. Collective agreements covering operating employees at GTW, ICC, WC, BLE and all employees at PCD continue to be bargained on a local (corporate) basis.

Where negotiations are ongoing, the terms and conditions of existing agreements generally continue to apply until new agreements are reached or the processes of the Railway Labor Act have been exhausted.

2015 Highlights

Strategic Initiatives and Capital Spending

In 2015, CN spent $2.7 billion in its capital program, with $1.53 billion targeted at maintaining the safety and integrity of the network, particularly track infrastructure. This investment included the replacement of rail, ties, and other track materials, bridge improvements, as well as various branch line upgrades. CN invested significantly to build for the future, increasing network capacity, resilience and fluidity across its network, including its Edmonton-Winnipeg and Winnipeg-Chicago corridors. As part of its overall capital program, CN invested more than $120 million in 2015 to install sections of double tracks, extended sidings, crossovers and yard improvements on main lines in the two corridors.

In 2015, CN’s equipment capital expenditures reached $555 million, allowing the Company to be ready for growth opportunities and to improve the quality of the fleet, including the acquisition of 90 new high-horsepower locomotives. Orders have been placed for 90 additional new locomotives which were delivered in 2016. CN also spent $615 million on initiatives to support growth and drive productivity, such as transloads and distribution centers; and information technology to improve service and operating efficiency.

The Company strengthened its commitment to Operational and Service Excellence through a wide range of innovations anchored on its continuous improvement philosophy. CN built on its industry leadership in terms of fast and reliable hub-to-hub service by continuing to improve across the range of customer touch points. The Company’s

Financial Management Initiatives

The Company established a commercial paper program in the U.S. during the second quarter of 2015 in addition to its existing commercial paper program in Canada. Both programs are backstopped by the Company’s revolving credit facility, enabling it to issue commercial paper up to a maximum aggregate principal amount of $800 million, or the U.S. dollar equivalent, on a combined basis. As at December 31, 2015, the Company had total commercial paper borrowings of $458 million (U.S. $331 million). The weighted-average interest rate on these borrowings was 0.41%.

The Company has an agreement to sell an undivided co-ownership interest in a revolving pool of accounts receivable to unrelated trusts for maximum cash proceeds of $450 million. On June 18, 2015, the expiry date of the agreement was extended by one year to February 1, 2018. As at December 31, 2015, the Company had no proceeds received under the accounts receivable securitization program. The accounts receivable securitization program provides the Company with readily available short-term financing for general corporate use.

The Company has an $800 million revolving credit facility agreement with a consortium of lenders. The agreement, which contains customary terms and conditions, allows for an increase in the facility amount, up to a maximum of $1.3 billion, as well as the option to extend the term by an additional year at each anniversary date, subject to the consent of individual lenders. The Company exercised such option, and on March 12, 2015, the expiry date of the agreement was extended by one year to May 5, 2020. The credit facility is available for general corporate purposes, including back-stopping the Company’s commercial paper program, and provides for borrowings at various interest rates, including the Canadian prime rate, bankers’ acceptance rates, the U.S. federal funds effective rate and the London Interbank Offered Rate (LIBOR), plus applicable margins. The credit facility agreement has one financial covenant, which limits debt as a percentage of total capitalization, and with which the Company is in compliance. As at December 31, 2015, the Company had no outstanding borrowings under its revolving credit facility and there were no draws during the year ended December 31, 2015.

The Company has a series of bilateral letter of credit facility agreements with various banks to support its requirements to post letters of credit in the ordinary course of business. On March 12, 2015 the expiry date of these agreements was extended by one year to April 28, 2018. Under these agreements, the Company has the option from time to time to pledge collateral in the form of cash or cash equivalents, for a minimum term of one month, equal to at least the face value of the letters of credit issued. As at December 31, 2015, the Company had letters of credit drawn of $551 million from a total committed amount of $575 million by the various banks. As at December 31, 2015, cash and cash equivalents of $523 million were pledged as collateral and recorded as Restricted cash and cash equivalents on the Consolidated Balance Sheet.

On September 11, 2015, CN announced that the TSX had accepted CN’s amended 2014-2015 notice of intention of October 2014 to make a normal course issuer bid.

U.S. workforce

As of February 1, 2016, the Company had in place agreements with bargaining units representing the entire unionized workforce at Grand Trunk Western Railroad Company (GTW), companies owned by Illinois Central Corporation (ICC), companies owned by Wisconsin Central Ltd. (WC), Bessemer & Lake Erie Railroad Company (BLE) and The Pittsburgh and Conneaut Dock Company (PCD). Agreements in place have various moratorium provisions up to 2018, which preserve the status quo in respect of the given collective agreement during the terms of such moratoriums. All collective agreements covering non-operating craft employees and four collective agreements covering operating craft employees are currently under renegotiation.

During 2015, the Company renewed a collective agreement with the United Transportation Union (UTU) (a division of the International Association of Sheet Metal, Air, Rail, and Transportation Workers - SMART) governing conductors on the Grand Trunk Western. On January 15, 2016, the Company renewed three additional collective agreements with UTU, governing 57 yardmasters at GTW, WC, and a small subset working on the ICC.

The general approach to labor negotiations by U.S. Class I railroads is to bargain on a collective national basis with the industry, which GTW, ICC, WC and BLE have agreed to participate in, effective January 2015, for collective agreements covering non-operating employees. Collective agreements covering operating employees at GTW, ICC, WC, BLE and all employees at PCD continue to be bargained on a local (corporate) basis.

2014 Highlights

Acquisitions and Dispositions

On February 28, 2014, the Company closed a transaction with Agence Métropolitaine de Transport to sell the Deux-Montagnes subdivision between Saint-Eustache and Montreal, Quebec, including the Mont-Royal tunnel, together with the rail fixtures (collectively Deux-Montagnes), for cash proceeds of $97 million before transaction costs. Under the agreement, the Company obtained the perpetual right to operate freight trains over the Deux-Montagnes at its then current level of operating activity, with the possibility of increasing its operating activity for additional consideration. The transaction resulted in a gain on disposal of $80 million ($72 million after-tax) that was recorded in Other income under the full accrual method of accounting for real estate transactions.

On September 4, 2014, the Company closed a transaction with Metrolinx to sell a segment of the Guelph subdivision located between Georgetown and Kitchener, Ontario, together with the rail fixtures and certain passenger agreements (collectively the Guelph), for cash proceeds of $76 million before transaction costs. The Company did not meet all the conditions to record the sale under the full accrual method for real estate transactions as it continues to have substantial continuing involvement on the Guelph. The Company will have relinquished substantially all of

the risks and rewards of ownership on the Guelph in 2018, at which time the gain on the sale is expected to be recognized.

Strategic Initiatives and Capital Spending

In 2014, CN spent approximately $2.3 billion in its capital program, with $1.25 billion targeted at maintaining the safety and integrity of the network. This investment included the replacement of rail, ties, and other track materials, bridge improvements, as well as various branch line upgrades. CN invested significantly to build for the future, increasing network capacity, resilience and fluidity across its network, including its Edmonton-Winnipeg and Winnipeg-Chicago corridors. As part of its overall capital program, CN invested more than $100 million in 2014 to install sections of double tracks, extended sidings, crossovers, high-speed switches and yard improvements on main lines in the two corridors.

In 2014, CN’s equipment capital expenditures reached approximately $375 million, allowing the Company to tap growth opportunities and improve the quality of the fleet. In order to handle the expected traffic increase and improve operational efficiency, 60 new high-horsepower locomotives were added to the fleet in 2014. Furthermore, orders were placed for 180 additional new locomotives: 90 delivered in 2015 and 90 delivered in 2016. CN also spent approximately $575 million on initiatives to support growth and drive productivity, such as transloads and distribution centers; and information technology to improve service and operating efficiency.

As part of its objective to build a solid team of railroaders, the Company opened two new state-of-the-art training facilities in 2014, in Winnipeg, Manitoba and Homewood, Illinois, at a cost of $55 million, aimed at preparing employees to be highly skilled, safety conscious and confident in their work environment. Curricula for technical training and leadership development was also improved to meet the learning needs of CN’s railroaders – both current and future. These programs and initiatives provided a solid platform for the assessment and development of the Company’s talent pool, and are tightly integrated with the Company’s business strategy.

The Company also strengthened its commitment to Operational and Service Excellence through a wide range of innovations anchored on its continuous improvement philosophy. Through a portfolio of initiatives called CustomerFIRST, the Company innovated to address key customer pinch points, including the first-mile and last-mile of the shipment cycle. iAdvise, an information tool that is improving the reliability and consistency of shipment information, was the latest initiative in CN’s strategy to communicate better with customers. In 2014, CN rolled out its iAdvise tool to a significant number of its largest customers.

3.2 STRATEGY OVERVIEW

For a discussion of the Company’s business strategy and anticipated developments for 2017, please see the section entitled “Strategy overview” on pages 3 to 6 of the MD&A, which are incorporated by reference herein. The MD&A may be found on SEDAR at www.sedar.com and on EDGAR at www.sec.gov and on the Company’s website at cn.ca in the Investors section.

ITEM 4 DESCRIPTION OF THE BUSINESS

4.1 OVERVIEW

CN is engaged in the rail and related transportation business. CN’s network of approximately 20,000 route miles of track spans Canada and mid-America, uniquely connecting three coasts: the Atlantic, the Pacific and the Gulf of Mexico and serving the cities and ports of Vancouver, Prince Rupert (British Columbia), Montreal, Halifax, New Orleans, and Mobile (Alabama), and the metropolitan areas of Toronto, Edmonton, Winnipeg, Calgary, Chicago, Memphis, Detroit, Duluth (Minnesota)/Superior (Wisconsin), and Jackson (Mississippi), with connections to all points in North America. CN’s extensive network and efficient connections to all Class I railroads provide CN customers access to all three North American Free Trade Agreement (NAFTA) nations. CN handles over $250 billion worth of goods annually and carries almost 300 million tons of cargo, serving exporters, importers, retailers, farmers and manufacturers.

CN’s freight revenues are derived from seven commodity groups representing a diversified and balanced portfolio of goods transported between a wide range of origins and destinations. This product and geographic diversity better positions the Company to face economic fluctuations and enhances its potential for growth opportunities. In 2016, no individual commodity group accounted for more than 24% of total revenues. From a geographic standpoint, 17% of revenues relate to U.S. domestic traffic, 34% transborder traffic, 18% Canadian domestic traffic and 31% overseas traffic. The Company is the originating carrier for approximately 85% of traffic moving along its network, which allows it both to capitalize on service advantages and build on opportunities to efficiently use assets.

Revenues generated by the Company during the year are influenced by seasonal weather conditions, general economic conditions, cyclical demand for rail transportation, and competitive forces in the transportation marketplace. Operating expenses reflect the impact of freight volumes, seasonal weather conditions, labor costs, fuel prices, and the Company’s productivity initiatives.

4.3 COMPETITIVE CONDITIONS

For a discussion of the competitive conditions under which CN operates, please see the section entitled “Competition” in the Business risks discussion located on page 41 of the MD&A, which is incorporated by reference herein.

4.4 LABOR

As at December 31, 2016, CN employed a total of 22,249 employees, of which 16,621 were unionized employees.

For a discussion of CN’s labour negotiations, please see the section entitled “Labor negotiations” in the Business risks discussion located on page 43 of the MD&A, which are incorporated by reference herein.

4.5 SOCIAL POLICIES

In addition to its Employment Equity Policy (for Canadian employees) and Equal Employment Opportunity Policy (for U.S. employees), CN maintains a comprehensive Human Rights Policy and a Harassment Free Environment Policy for its Canadian employees and a Prohibited Harassment, Discrimination and Anti-Retaliation Policy for its U.S. employees. These policies affirm CN’s commitment to ensuring that there is no discrimination against any employee or applicant based on grounds of religion, race, sex, nationality, disability or any other prohibited grounds of discrimination. The policy extends to recruitment, selection and compensation practices, as well as to working conditions and the work environment. All Company vice-presidents have been mandated with the responsibility of implementing these policies and ensuring that all work practices are in compliance. Internal complaint procedures have been established whereby any person covered by the Harassment Free Environment Policy and the Employment Equity Policy (for Canadian employees) or the Equal Employment Opportunity Policy and Prohibited Harassment, Discrimination and Anti-Retaliation Policy (for U.S. employees) can contact his or her human resources director or human resources manager who will address his or her complaint. The employee can also call either the Human Resources Center, which will forward the complaint to the appropriate human resources manager for further handling, or the CN Ombudsman directly, who can be contacted on a confidential basis. As part of CN’s commitment to providing a safe, healthy and violence-free workplace for all employees, CN has in place a Workplace Violence Prevention Policy which applies to all employees. The objective of this policy is to reiterate the prohibition of workplace violence at CN and set out how threats, acts or risks of workplace violence are to be reported and addressed.

4.6 REGULATION

The Company’s operations are subject to regulations both in Canada and in the U.S. A summary of such regulations is provided below. For a complete discussion of recent and pending legislative and other regulatory developments both in Canada and in the U.S., see the section entitled “Regulation” in the Business risks discussion located on pages 43 to 48 of the MD&A, which are incorporated by reference herein.

Economic regulation – Canada

The Company’s rail operations in Canada are subject to economic regulation by the Canadian Transportation Agency (Agency) under the Canada Transportation Act (CTA). The CTA provides rate and service remedies, including final

Table of Contents

2016 Annual Information Form

offer arbitration (FOA), competitive line rates and compulsory interswitching. It also regulates the maximum revenue entitlement for the movement of regulated grain, charges for railway ancillary services and noise-related disputes. In addition, various Company business transactions must gain prior regulatory approval, with attendant risks and uncertainties, and the Company is subject to government oversight with respect to rate, service and business practice issues.

The CTA gives railroads in Canada the freedom to negotiate prices according to market forces, subject to certain provisions aimed at protecting shippers. These shipper protections include, inter alia, interswitching, final offer arbitration, competitive line rates and the right to seek a regulatory order as to the reasonableness of the terms and conditions imposed by carriers for incidental services. Pursuant to the interswitching provisions, shippers within a 30 kilometers radius (approximately 19 miles) of an interchange between two federally regulated railroads have access to the other railway at a prescribed interswitching rate. During 2014, Bill C-30 came into force pursuant to which the Agency issued an amendment to the interswitching regulations extending the distance to 160 kilometers from the previous 30 kilometers limits for all commodities in the provinces of Manitoba, Saskatchewan and Alberta; and issued regulations defining what constitutes “operational terms” for the purpose of rail level of service arbitrations. On June 15, 2016, the Government of Canada announced that the provisions introduced by Bill C-30 which were set to expire on August 1, 2016, had been extended until August 2017. Final offer arbitration is used in cases of rate disputes between a shipper and a railroad and involves the selection by an arbitrator of either the shipper’s or the carrier’s rate and service offer. Competitive line rate provisions can be invoked to require an originating railroad to issue to a shipper with access to a single rail carrier, a rate covering the movement to the nearest junction with another railroad according to predetermined formulae. In addition, certain rail shipments of export grain are subject to a government-established revenue cap, which effectively specifies a maximum revenue entitlement that railways can earn.

To supplement public rates issued under tariffs, the CTA permits confidential contracts to be negotiated between rail carriers and shippers to govern the terms, conditions and rates for service. Furthermore, railroads are subject to service level obligations and, in case of breach, shippers may seek redress from the Agency. Railroads are also required to enter into an agreement, at the request of a shipper, respecting the manner in which it intends to fulfill its service obligations. In the absence of an agreement, the shipper may submit the matter for determination by an arbitrator.

When a railroad operator wants to sell or abandon lines, the CTA encourages their sale to other railroad operators and provides the framework for line discontinuance. The railroads are required to publish a plan for lines they intend to discontinue within the next three years. Prior to discontinuance, the line must be advertised as being for sale for continued rail operation and, if no interest is shown, must be offered specifically for sale to applicable federal, provincial and municipal governments as well as urban transit authorities. The entire process is intended to take, at most, 24 months. The Company’s operations are also subject to safety and environmental provisions relating to track standards, equipment standards, transportation of hazardous materials, environmental assessments and certain labor regulations, which are in many respects similar when comparing Canadian and U.S. regulations.

In addition, periodically, a comprehensive review is made by the federal government of the effectiveness of the CTA, the Canadian Railway Safety Act and other statutes related to transportation, which may prompt regulatory amendments as a result. On June 25, 2014, the Government of Canada launched a statutory review of the CTA. The review concluded on December 21, 2015 when a report was submitted to the Federal Minister of Transport by the Chair of the review panel. The report was tabled in Parliament on February 25, 2016 by the Federal Minister of Transport, and on November 3, 2016, he announced that amendments to the CTA would be introduced in 2017 respecting the provisions of Bill C-30, the maximum revenue entitlement, reciprocal monetary penalties, the definition of the statutory level of services obligations and the timelines of Agency decisions. On November 3, 2016, the Minister of Transport also announced that the review of the Railway Safety Act which was initially scheduled for 2018 would be initiated in 2017 in order to further improve railway safety.

Economic regulation – U.S.

The Company’s U.S. rail operations are subject to economic regulation by the Surface Transportation Board (STB). The STB serves as both an adjudicatory and regulatory body and has jurisdiction over, amongst other things, service levels, carrier practices, car compensation, and limited jurisdiction over carrier rates. It also has jurisdiction over the situations and terms under which one railroad may gain access to another railroad’s traffic or facilities, the construction, extension, or abandonment of rail lines, railroad consolidations, and labor protection provisions in connection with the foregoing. The STB’s jurisdiction in these areas of rail transportation, including intrastate rail transportation, is exclusive, pre-empting other remedies under U.S. federal and state laws. As such, various Company business transactions must gain prior regulatory approval and aspects of its pricing and service practices may be subject to challenge, with attendant risks and uncertainties. The STB has undertaken proceedings in the past few years in a number of significant matters that remain pending. For further details on such proceedings, see the section entitled “Regulation – Economic regulation - U.S.” in the Business risks discussion located on page 44 of the MD&A, which is incorporated by reference herein.

Government regulation of the railroad industry is a significant determinant of the competitiveness and profitability of railroads. Deregulation of certain rates and services, plus the ability to enter into confidential contracts, pursuant to the Staggers Rail Act of 1980 (Staggers Act), has substantially increased the flexibility of railroads to respond to market forces and has resulted in highly competitive rates. Various interests have sought and continue to seek reimposition of government controls on the railroad industry in areas deregulated in whole or in part by the Staggers Act. Additional regulation, changes in regulation and re-regulation of the industry through legislative, administrative, judicial or other action could materially affect the Company.

Safety regulation – Canada

The Company’s rail operations in Canada are subject to safety regulation by the Federal Minister of Transport under the Railway Safety Act as well as the rail portions of other safety-related statutes, which are administered by Transport Canada. The Company may be required to transport toxic inhalation hazard materials as a result of its common carrier obligations and, as such, is exposed to additional regulatory oversight in Canada. The Transportation of Dangerous Goods Act, also administered by Transport Canada, establishes the safety requirements for the transportation of goods classified as dangerous and enables the establishment of regulations for security training and screening of personnel working with dangerous goods, as well as the development of a program to require a transportation security clearance for dangerous goods and that dangerous goods be tracked during transport.

Following a significant derailment involving a non-related short-line railroad within the Province of Quebec (Lac-Mégantic derailment) on July 6, 2013, several measures have been taken by Transport Canada to strengthen the safety of the railway and transportation of dangerous goods systems in Canada. Amendments to the Canada Railway Safety Act and Transportation of Dangerous Goods Act include requirements for classification and sampling of crude oil, the provision of yearly aggregate information on the nature and volume of dangerous goods the company transports by rail through designated municipalities, and new speed limit restrictions of 40 miles per hour for certain trains carrying dangerous commodities. Additional requirements for railway companies to conduct route assessments for rail corridors handling significant volumes of dangerous goods and an Emergency Response Assistance Plan in order to ship large volumes of flammable liquids were also put into place. Further to this, on April 28, 2016, Transport Canada issued a Protective Direction under which railways are required to provide municipalities and first responders with data on dangerous goods to improve emergency planning, risk assessment, and training.

In 2014, Transport Canada’s Grade Crossings Regulations came into force, which establish specific standards for new grade crossings and requirements that existing crossings be upgraded to basic safety standards within seven years, as well as safety related data that must be provided by railway companies on an annual basis. The Company has complied with the information requirements by providing road authorities with specific information respecting public grade crossings, as required by November 27, 2016.

2016 Annual Information Form

In 2015, Transport Canada issued rules prohibiting the use of certain DOT-111 tank cars for the transportation of dangerous goods, and announced a new standard for tank cars transporting flammable liquid dangerous goods. The new standard, called TC-117, establishes enhanced construction specifications along with a phase out schedule for DOT-111 and CPC-1232 tank cars. On July 25, 2016, Transport Canada issued a Protective Direction which accelerated the phasing out of DOT-111 tank cars in crude oil service by November 1, 2016.

On June 18, 2016, the liability and compensation regime for rail under the Safe and Accountable Rail Act came into force. Under the regime, railway companies are strictly liable for damages resulting from accidents involving crude oil and are required to maintain minimum liability insurance coverage in respect of losses incurred as a result of a railway accident involving crude oil. The Act creates a fund, capitalized through levies payable by crude oil shippers, to compensate for losses exceeding the railway company’s minimum insurance level. CN has provided the Agency with submissions respecting the adequacy of its insurance coverage and has started collecting the levy on crude shipments. As a result of this legislation, the Agency also now has jurisdiction to order railway companies to compensate municipalities for the costs incurred in responding to fires caused by railway operations.

Safety regulation – U.S.

The Company’s U.S. rail operations are subject to safety regulation by the Federal Railroad Administration (FRA) under the Federal Railroad Safety Act as well as rail portions of other safety statutes, with the transportation of certain hazardous commodities also governed by regulations promulgated by the Pipeline and Hazardous Materials Safety Administration (PHMSA). PHMSA requires carriers operating in the U.S. to report annually the volume and route-specific data for cars containing these commodities; conduct a safety and security risk analysis for each used route; identify a commercially practicable alternative route for each used route; and select for use the practical route posing the least safety and security risk. In addition, the Transportation Security Administration (TSA) requires rail carriers to provide upon request, within five minutes for a single car and 30 minutes for multiple cars, location and shipping information on cars on their networks containing toxic inhalation hazard materials and certain radioactive or explosive materials; and ensure the secure, attended transfer of all such cars to and from shippers, receivers and other carriers that will move from, to, or through designated high-threat urban areas.

The FRA also has jurisdiction over railroad safety and equipment standards, and most rail safety regulation is handled at the federal level. In contrast, however, to the exclusive role of the STB over railroad economic regulation, state and local regulatory agencies have jurisdiction over certain local safety and operating matters and these agencies are becoming more aggressive in their exercise of jurisdiction. State legislatures have also recently enacted new laws in this regard that are intended to regulate railroads more extensively.

In the aftermath of the July 2013 Lac-Mégantic derailment, the FRA issued Emergency Order No. 28, Notice No. 1 on August 2, 2013 directing that railroads take specific actions regarding unattended trains transporting specified hazardous materials, including securement of these trains. That same day, the FRA and the PHMSA issued Safety Advisory 2013-06, which made recommendations to railroads on issues including crew staffing practices and operational testing to ensure employees’ compliance with securement-related rules, as well as recommendations to shippers of crude oil to be transported by rail. In addition, the railroad industry has acted on its own to enhance rail safety in light of the Lac-Mégantic derailment and fire. Effective August 5, 2013, the Association of American Railroads amended the industry’s Recommended Railroad Operating Practices for Transportation of Hazardous Materials by expanding the definition of a “key train” (for which heightened operating safeguards are required).

Other regulations – Canada and U.S.

Positive train control (PTC)

On October 16, 2008, the U.S. Congress enacted the Rail Safety Improvement Act of 2008, which required all Class I railroads and intercity passenger and commuter railroads to implement a PTC system by December 31, 2015 on mainline track where intercity passenger railroads and commuter railroads operate and where toxic inhalation hazard materials are transported. PTC is a collision avoidance technology intended to override locomotive controls and stop a train before an accident. Pursuant to the Positive Train Control Enforcement and Implementation Act of 2015 and the FAST Act of 2015 (collectively, the PTCEIA), Congress extended the PTC installation deadline until December 31, 2018, with the option for a railroad carrier to finalize full implementation of PTC by no later than December 31, 2020, provided certain benchmarks are met by the end of 2018. Pursuant to the PTCEIA, the Company submitted its revised implementation plan on January 27, 2016 and a request for amendment on December 29, 2016. The Company filed its first annual progress report with the FRA on March 31, 2016, and its initial quarterly progress reports on July 31 and October 31, 2016. The Company is progressing its implementation of PTC pursuant to the law and is working with the FRA and other Class I railroads to satisfy the requirements for U.S. network interoperability.

Security

The Company is subject to statutory and regulatory directives in the U.S. addressing homeland security concerns. In the U.S., safety matters related to security are overseen by the TSA, which is part of the U.S. Department of Homeland Security (DHS) and PHMSA, which, like the FRA, is part of the U.S. Department of Transportation. Border security falls under the jurisdiction of U.S. Customs and Border Protection (CBP), which is part of DHS. In Canada, the Company is subject to regulation by the Canada Border Services Agency (CBSA). Matters related to agriculture-related shipments crossing the Canada/U.S. border also fall under the jurisdiction of the U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA) in the U.S. and the Canadian Food Inspection Agency (CFIA) in Canada.

More specifically, the Company is subject to:

· Border security arrangements, pursuant to an agreement the Company and Canadian Pacific Railway Company entered into with the CBP and the CBSA.

· The CBP’s Customs-Trade Partnership Against Terrorism program and designation as a low-risk carrier under CBSA’s Customs Self-Assessment program.

· Regulations imposed by the CBP requiring advance notification by all modes of transportation for all shipments into the U.S. The CBSA is also working on similar requirements for Canada-bound traffic.

· Inspection for imported fruits and vegetables grown in Canada and the agricultural quarantine and inspection user fee for all traffic entering the U.S. from Canada.

· Gamma ray screening of cargo entering the U.S. from Canada, and potential security and agricultural inspections at the Canada/U.S. border.

Vessels

The Company’s vessel operations are subject to regulation by the U.S. Coast Guard and the Department of Transportation, Maritime Administration, which regulate the ownership and operation of vessels operating on the Great Lakes and in U.S. coastal waters. In addition, the Environmental Protection Agency has authority to regulate air emissions from these vessels.

Table of Contents

2016 Annual Information Form

Transportation of hazardous materials

As a result of its common carrier obligations, the Company is legally required to transport toxic inhalation hazard materials regardless of risk or potential exposure or loss. A train accident involving the transport of these commodities could result in significant costs and claims for personal injury, property damage, and environmental penalties and remediation in excess of insurance coverage for these risks, which may materially adversely affect the Company’s results of operations, or its competitive and financial position.

4.7 ENVIRONMENTAL MATTERS

Regulatory Compliance

A risk of environmental liability is inherent in railroad and related transportation operations; real estate ownership, operation or control; and other commercial activities of the Company with respect to both current and past operations. As a result, the Company incurs significant operating and capital costs, on an ongoing basis, associated with environmental regulatory compliance and clean-up requirements in its railroad operations and relating to its past and present ownership, operation or control of real property. In as much as such liability is inherent to railroad and transportation operations, CN is in all material aspects similarly situated relative to its competitors and thus the resulting environmental protection requirements and expenditures are not expected to have a material adverse effect on CN’s competitive position. Environmental expenditures that relate to current operations are expensed unless they relate to an improvement to the property. Expenditures that relate to an existing condition caused by past operations and which are not expected to contribute to current or future operations are expensed.

In Canada, the matter of environmental permits for the Company is complex because of an overlap between federal and provincial jurisdictions. When projects trigger an environmental assessment, CN proceeds in accordance with the Canadian Environmental Assessment Act, 2012. Provincial and municipal environmental legislation may be applicable to railway activities if such legislation does not aim to regulate the management or operations of railways. Therefore, the Company does not apply systematically for provincial, municipal or local environmental permits for its railway operations in Canada except (i) where obtaining and complying with such permits would not interfere with the operations or management of its railway activities, (ii) where the work undertaken has an impact outside of CN’s right-of-way, (iii) where the Company or the governmental authority think it is necessary to obtain such permits to continue minor aspects of the Company’s railway operations or maintenance, or (iv) where the absence of a permit may affect a third party (such as a customer or a supplier). Because of the multiple jurisdictions involved and the extensive provincial legislative authority to regulate environmental matters, there can be no assurance that additional provincial, municipal or local environmental permits will not be required in the future. The Company may incur additional expenses or changes in its operations if such additional permits were to be required in the future.

See Note 16 – Major commitments and contingencies, to CN’s 2016 Annual Consolidated Financial Statements (Financial Statements) for a further discussion of environmental matters, as well as the section entitled “Environmental matters”, on pages 40 to 41 of the MD&A, and the section entitled “Environmental matters” in the Business risks discussion located on page 42 of the MD&A, which are incorporated by reference herein.

Environmental Policy

CN is committed to conducting its operations and activities in a manner that protects the natural environment. CN considers protecting the environment a fundamental corporate social responsibility governing its activities. Consequently, CN has implemented comprehensive environmental management programs. The Company’s programs aim to minimize the impact of the Company’s activities on the environment. The Company strives to contribute to the protection of the environment by integrating environmental priorities into the Company’s overall business plan and through the specific monitoring and measurement of such priorities against historical performance and, in some cases, specific targets.

Table of Contents

2016 Annual Information Form

The Environment, Safety and Security Committee of the Board of Directors has the responsibility of overseeing the Company’s environmental programs. The Environment, Safety and Security Committee is composed of CN’s directors and its responsibilities, powers and operation are further described in the charter of such committee, which is included in the Company’s Corporate Governance Manual available on CN’s website. Certain risk mitigation strategies, such as periodic audits, employee training programs and emergency plans and procedures, are in place to minimize the environmental risks to the Company. The Company’s CDP report, its Sustainability Report entitled “Delivering Responsibly” and the Company’s Corporate Governance Manual, are available on CN’s website www.cn.ca in the Delivering Responsibly section.

4.8 LEGAL MATTERS

Legal Proceedings

As of the date hereof, there are no legal proceedings to which CN is a party involving claims for damages, exclusive of interest and costs, in excess of 10% of its current assets. The Company will regularly assess its position as events progress.

See Note 16 – Major commitments and contingencies to the Financial Statements, for further discussion of legal actions, if any, as well as pages 38 to 39 of the MD&A, for a general discussion of personal injury and other claims, which are incorporated by reference herein.

Aboriginal Claims

CN and its predecessor companies have acquired lands throughout Canada from the Crown, including certain lands contained in Aboriginal reserves. A portion of the Company’s network, primarily in British Columbia, is currently operated on these lands.

The Company believes that it possesses unrestricted and absolute title to lands acquired out of Aboriginal reserves. However, in recent years, some Aboriginal bands have claimed to have a continuing legal interest in such lands. They allege this interest prohibits the Company from disposing of the lands when they are no longer needed for railway purposes, except by allowing them to revert to the Crown for the benefit of Aboriginals. This issue is one which will ultimately be decided by the courts; however, regardless of the outcome, there is no perceived material adverse effect, as the right of the Company to continue to occupy and operate over such lands is not being called into question.

As the issues surrounding Aboriginal claims are complex and involve not only private interests but fiduciary and other obligations of the Crown in the right of Canada, CN has agreed not to sell or otherwise dispose of land which is not essential to its rail operations and which is located in, or adjacent to, an Aboriginal reserve, unless each of CN and the Government of Canada is satisfied that no legitimate Aboriginal claim exists with respect to such land. In addition, CN has agreed to convey to the Government of Canada, for no consideration, any land not integral to its rail operations that may be necessary to settle legitimate Aboriginal claims with respect to such land, or lands which were formerly reserve lands and have become non-rail assets. The Government of Canada, for its part, has agreed that it will provide the necessary compensation for settlement of legitimate Aboriginal claims which would otherwise result in CN having to relinquish land essential to its rail network, unless such claims arise out of, or are substantially based upon, willful, known, negligent or fraudulent acts or omissions of CN which adversely affected the rights or interests of Aboriginal people.

4.9 INTANGIBLE PROPERTIES

CN uses various works protected by intellectual property rights to which the Company owns or for which it has been granted rights to use. These works include customers’ lists, copyrights, patents, trade-marks, logos and trade names. This intellectual property is important to the Company’s operations and its success.

4.10 RISK FACTORS

A description of risks affecting CN and its business appears under the heading “Business risks” located on pages 41 to 50 of the MD&A, and under the heading “Financial Instruments” for risks associated with the Company’s use of financial instruments located on pages 30 to 31 of the MD&A, which pages are incorporated by reference herein. See Item 1 of this AIF for a further discussion of risks associated with forward-looking statements.

ITEM 5 DIVIDENDS

The Company has declared dividends in line with its overall financial performance and cash flow generation. The Board of Directors makes decisions on dividend levels on an annual basis and on dividend payout on a quarterly basis. Consistent with this practice, the quarterly rate of $0.2500 per share, starting with the first quarter of 2014, was increased to $0.3125 per share, starting with the first quarter of 2015; the quarterly dividend was next increased to $0.3750 per share, starting with the first quarter of 2016 and to $0.4125 per share, starting with the first quarter of 2017. There can be no assurance as to the amount or timing of such dividends in the future.

ITEM 6 DESCRIPTION OF CAPITAL STRUCTURE

6.1 GENERAL DESCRIPTION OF CAPITAL STRUCTURE

The authorized share capital of CN consists of an unlimited number of Common Shares, an unlimited number of Class A Preferred Shares issuable in series and an unlimited number of Class B Preferred Shares issuable in series, all without par value.

There are no Class A Preferred Shares or any Class B Preferred Shares currently issued and outstanding.

Common Shares

The Common Shares carry and are subject to the following rights, privileges, restrictions and conditions described below:

Voting: Each Common Share entitles its holder to receive notice of and to attend all general and special meetings of shareholders of CN, other than meetings at which only the holders of a particular class or series of shares are entitled to vote, and each such Common Share entitles its holder to one vote.

Dividends: The holders of Common Shares are, at the discretion of the directors, entitled to receive, out of any amounts applicable to the payment of dividends, and after the payment of any dividends payable on any Preferred Shares, any dividends declared and payable by CN on the Common Shares.

Dissolution: The holders of Common Shares shall be entitled to share equally in any distribution of the assets of CN upon the liquidation, dissolution or winding-up of CN or other distribution of its assets among its shareholders. Such participation is subject to the rights, privileges, restrictions and conditions attaching to any issued and outstanding Preferred Shares or shares of any other class ranking prior to the Common Shares.

Table of Contents

2016 Annual Information Form

Preferred Shares

The Class A Preferred Shares and the Class B Preferred Shares are issuable in series and, subject to CN’s Articles, the Board of Directors is authorized to fix, before issuance, the designation, rights, privileges, restrictions and conditions attaching to the shares of each series. The holders of Class A Preferred Shares or Class B Preferred Shares shall not be entitled to vote at meetings of shareholders otherwise than as provided by law and holders of Class A Preferred Shares or Class B Preferred Shares shall not be entitled to vote separately as a class except as provided by law.

6.2 SHARE OWNERSHIP CONSTRAINTS

CN’s Articles provide that where the total number of voting shares held, beneficially owned, or controlled, directly or indirectly, by any one person together with his or her associates exceed 15%, no person shall exercise the voting rights attached to the voting shares held, beneficially owned or controlled, directly or indirectly, by such person or his or her associates. Furthermore, all dividends attributable to the percentage of voting shares held by such persons in excess of 15% shall be forfeited, including any cumulative dividend. However, CN’s Articles provide that in the event where the 15% limit is exceeded solely as a result of share buybacks conducted by CN, the only consequence to the relevant shareholder under CN’s Articles is that the shareholder shall not be entitled to exercise the voting rights attached to the common shares held by such shareholder that are in excess of the 15% limit. CN’s Articles confer on the Board of Directors all powers necessary to give effect to the ownership restrictions, including the ability to pay dividends or to make other distributions which would otherwise be prohibited if the event giving rise to the prohibition was inadvertent or of a technical nature or it would otherwise be inequitable not to pay the dividends or make the distribution. CN’s Articles provide that the Board of Directors may adopt by-laws concerning the administration of the constrained share provisions described above, including by-laws requiring a shareholder to furnish a declaration indicating whether he or she is the beneficial owner of the shares and whether he or she is an associate of any other shareholder. In addition, CN is also authorized to refuse to recognize the ownership rights that would otherwise be attached to any voting shares held, beneficially owned or controlled, directly or indirectly, contrary to the share ownership constraint. Finally, CN has the right, for the purpose of enforcing any constraint imposed pursuant to its Articles, to sell, as if it were the owner thereof, any voting shares that are owned or that the directors determine may be owned, by any person or persons contrary to such share ownership constraint.

6.3 RATINGS OF DEBT SECURITIES

The Company’s access to long-term funds in the debt capital markets depends on its credit rating and market conditions. The Company believes that it continues to have access to the long-term debt capital markets. Rating downgrades could limit the Company’s access to the credit markets, or increase its borrowing costs. Various classes of CN’s outstanding securities have been rated by several rating organizations as described in detail below, as of the date hereof.

DBRS

Moody’s Investors Service

Standard & Poor’s

Long-Term Debt

Commercial Paper

R-1 (low)

P-1

A-1

The above-noted ratings are given the following credit characteristics by the various rating agencies:

Table of Contents

2016 Annual Information Form

DBRS Limited (DBRS)

· Long-term debt rated A is of good credit quality. The capacity for the payment of financial obligations is substantial, but of lesser quality than AA. May be vulnerable to future events, but qualifying negative factors are considered manageable. This rating falls within the third highest of DBRS’s ten long-term debt rating categories which range from “AAA” to “D”.

· Commercial paper rated R-1 (low) is of good credit quality. The capacity for the payment of short-term financial obligations as they fall due is substantial. Overall strength is not as favourable as higher rating categories. May be vulnerable to future events, but qualifying negative factors are considered manageable. This rating falls within the third highest of DBRS’s ten short-term debt rating categories which range from “R-1 (high)” to “D”.

Moody’s Investors Service (Moody’s)

· Long-term debt obligations rated A are judged to be upper-medium grade and are subject to low credit risk. This rating falls within the third highest of Moody’s nine generic long-term obligation rating categories which range from “Aaa” to “C”. The modifier “2” indicates a ranking in the mid-range of that generic rating category.

· Commercial paper rated P-1 indicates that CN has a superior ability to repay short-term debt obligations. This rating falls within the highest of Moody’s four generic short-term debt rating categories which range from “P-1” to “NP”.

Standard & Poor’s Financial Services LLC (S&P)

· Long-term debt obligations rated A are somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligations is still strong. This rating falls within the third highest of S&P’s ten major long-term credit rating categories which range from “AAA” to “D”.

· A short-term obligation rated “A-1” is rated in the highest category by S&P. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

The ratings of CN’s securities described above should not be construed as a recommendation to buy, sell, or hold CN securities. Ratings may be revised or withdrawn at any time by the rating agencies.

As is common practice, during the last two years, each of the above-noted credit rating agencies charged CN for their rating services which include annual surveillance fees covering CN’s outstanding long-term and short-term debt securities, in addition to one-time rating fees when debt is initially issued. CN reasonably expects that such payments will continue to be made for rating services in the future.

ITEM 7 TRANSFER AGENT AND REGISTRAR

In Canada, the transfer agent and registrar for each class of CN’s publicly issued securities is Computershare Trust Company of Canada and, in the U.S., the co-transfer agent and co-registrar is Computershare Trust Company, N.A., both of which maintain registers of transfers for CN’s securities at the locations specified below:
