Explains when Mississauga condo owners can legally rekey their mailbox lock, when Canada Post rules apply, and what to do if you've lost your mailbox key.
This is a topic our Mississauga-based team gets asked about constantly. Below we walk through what you actually need to know, in plain language, from the perspective of locksmiths who handle these calls across the Mississauga area every day.
If you would rather just have it handled, we are a phone call away at (289) 206-5983 — 24 hours a day. We will give you a clear price before any work starts.
