I've just found the answer to this problem. You have to add an extra digi to the branch number as per bellow. In a Canadian bank transit number, the last digit of the branch number, with few exceptions, indicates the geographical location of the branch. Branch numbers ending with: * 0 are located in British Columbia and Yukon * 1 are located in Western Québec including Montreal and surrounding areas * 2 are located in Ontario including Toronto and surrounding area * 3 are located in Nova Scotia, Prince Edward Island and Newfoundland excluding Labrador * 4 are located in New Brunswick * 5 are located in Eastern Québec including Labrador * 6 are located in Eastern Ontario including Ottawa and surrounding area * 7 are located in Manitoba and North-Western Ontario * 8 are located in Saskatchewan * 9 are located in Alberta, the Northwest Territories and Nunavut (?)
