Option 1: Look at your checkbook
If you have your checkbook to hand, have a look at the illustration below for how to find these details.
Option 2: Log into your internet banking
You can usually find these details by logging into your internet bank. From there you should easily be able to see the account number of the account you would like to use, the institution number of the bank and the transit number of the branch.
Option 3: Find the Institution number in the list below
Here is a list of institution numbers for Canadian Banks.
Please note: These numbers are accurate to the best of our knowledge, but if you are unsure it is always best to check with the recipient's bank. These numbers should only be used to confirm details you already have.
Option 4: Routing Number
Sometimes banks display institution and transit numbers as a routing number. A routing number for electronic payments contains a zero (called the "leading zero"), a three-digit financial institution number and a five-digit branch number.
Routing number format:
YYY - institution number
XXXXX - transit number
For example, if Bank’s routing number is 026011242, the institution number is 260, and the transit number is 11242.
You can check the validity of the Institution and Transit number combination on Canada Banks Information website: http://canada-banks-info.com/routing-numbers
