You can find your route and transit number on the bottom of your Affinity cheques, as shown on the cheque image below:

The first 3 numbers on the cheque are the cheque number. The 5 digits following the cheque number are your transit number and the next 3 digits are your route number. The rest of the numbers on the cheque are your account number.
If you don’t have cheques, you can get this information through online banking by clicking the ‘Direct Deposit and Pre-Authorized Debit Form’ link.
