Does anyone know why the "Rate Codes Table" from the Canada Post Guide, does not show all postal codes in Ontario. (I haven't checked the other provinces). I am looking up the cost to ship to Mississauga Ontario, from Gravenhurst, Ontario, and there are no postal codes for Mississauga on the list. I know I can use other methods to calculate rates, but I've always liked this method. Here is the list.
