Toronto postal codes. A clear place to start.

What the result means.

The first three characters identify a postal area. This directory matches those prefixes; it does not check every complete six-character code against an address database. A matched prefix is a useful starting point, not proof of a valid street address or a confirmed appointment.

M7R is a Mississauga postal area and is excluded. Specialized Toronto office or mailing prefixes M5K, M5L, M5W, M5X, M7A and M7Y are not treated as ordinary residential coverage. Use the actual residential postal code of the home you want cleaned.

The directory uses a 2021 Census postal-area baseline and Canada Post reference information checked in October 2026. District groupings are approximate orientation labels. If your address or prefix is uncertain, verify it with Canada Post before making an enquiry.
