Notice-and-access

Protecting the environment – As part of our ongoing commitment to protect the environment and accelerate climate action, we are reducing the number of paper documents that we send to our shareholders. You have told us how important environmental sustainability is to you and we are listening as we execute on our ESG strategy and related net-zero ambition.

Our Management Proxy Circular – We are using notice-and-access to send our registered and non-registered shareholders the 2023 management proxy circular (Circular) as permitted by the Canadian Securities Administrators and with the authorization of the Office of the Superintendent of Financial Institutions Canada. This means that our Circular will be posted online for you to access, rather than being printed and mailed to you. This notice includes information on how to access the Circular online or how to request a paper copy. We also enclose a proxy form (if you are a registered shareholder) or voting instruction form (if you are a non-registered shareholder). This form allows you to exercise your voting rights. For information on how to vote, see “Voting” below.

It is important that you read the Circular carefully before voting your shares.

Our Annual Financial Statements and Management’s Discussion and Analysis – The way we send you our annual financial statements and management’s discussion and analysis (MD&A) (together with our Circular, the “meeting materials”) depends on whether you are a registered shareholder or a non-registered shareholder (see definitions on the reverse page). If you are a registered shareholder and you did not sign-up for e-delivery or opt out of receiving our annual financial statements, then we are required to send you our annual financial statements and you will receive a paper copy of our Annual Report with this notice. If you are a non-registered shareholder, then we will use notice-and-access to send you our annual financial statements and MD&A as permitted by securities law so that you can access this material online the same way as our Circular.

If you are a non-registered shareholder and wish to attend the virtual meeting through our live webcast and vote online, there are additional steps you MUST take.
