The selfie you submit is used to verify your identity.
When you sign up for a Tims Mastercard, you're asked to take and submit two pictures— one of your photo ID and a selfie (front profile). These photos are used to ensure that your identity and details match the information that you've provided.
What happens with the photos afterwards?
The pictures of you and your ID will be deleted within 30 days of the verification process being completed.
