__NOTOC__ This is a list of postal codes in Canada where the first letter is M. Postal codes beginning with M (except M0R and M7R) are located within the city of Toronto in the province of Ontario. Only the first three characters are listed, corresponding to the Forward Sortation Area (FSA).
Canada Post provides a free postal code look-up tool on its website, via its applications for smartphones, and sells hard-copy directories and CD-ROMs. Many vendors also sell validation tools, which allow customers to properly match addresses and postal codes. Hard-copy directories can also be consulted in all post offices, and some libraries.
Toronto
There are currently 103 FSAs in this list. There are no rural FSAs in Toronto, hence no postal codes should start with M0. However, a handful of individual special-purpose codes in the M0R FSA are assigned to "Gateway Commercial Returns, 4567 Dixie Rd, Mississauga" (which is actually within the L postal code area) as a merchandise returns label for freepost returns to high-volume vendors such as Amazon and the Shopping Channel.https://www.tsc.ca/pages/customer-service/return-instructions - the "4567 Dixie" address is Canada Post's Gateway sorting facility, not the original vendor.
