Sorry, only one Tims Rewards card can be linked to an account at a time. If you try to link a second card, the card that was previously linked to your account will be deactivated and replaced with the new card number.
Don't worry though, the points from that Tims Rewards card aren’t lost! Those points are still tied to your Tim Hortons account and will now be linked to the new Tims Rewards card you added.
Please note: Only one account can be created per email address.
