In Canada, your bank routing number is a combination of your transit number and your financial institution number. Your transit number identifies your bank branch location — where your bank is located in Canada. Your financial institution number identifies the bank. For instance, if you were looking for a routing number for TD and your branch was located in Toronto then the transit number is the branch number, let's say 11662 combined with the financial institution number, in this case 004. Combined, the number is 11662-004 and is the equivalent of a routing number. Keep in mind, US routing numbers and Canadian routing number combinations are not interchangeable.
