Exhibit 99.3

Notice of 2021 annual meeting of shareholders and notice of availability of our meeting materials

You are receiving this notice as a CIBC shareholder

The health and well-being of our team, clients, investors and communities remains our top priority. In line with the latest directives from public health and government authorities, this year’s meeting will be virtual by live webcast and telephone.

Notice-and-access

Protecting the environment – We are proud to let you know that we have furthered our commitment to protect the environment by reducing the amount of paper we send to our shareholders. You have told us how important environmental sustainability is to you as shareholders and we are listening.

Our Management Proxy Circular – Starting this year, we are using notice-and-access to send our registered and non-registered shareholders the 2021 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 and 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 below). 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.
