You can create a new Chexy account after deleting your previous account.
However, there are important limitations attached specifically to the aeroplan number attached.
What Happens to My Aeroplan Number?
You will not be able to attach a new Aeroplan number to the new account for promotional purposes.
Promotions are limited to one account per user.
To prevent duplicate rewards:
A block may be applied to the Aeroplan number previously used
This ensures multiple promotions are not issued to the same individual
Why Is This Policy in Place?
Promotional offers are:
Limited to one per eligible user
Monitored to prevent duplicate redemptions
Deleting and recreating an account does not reset promotional eligibility.
