Mailbox Lock Replacement in Toronto: Condo Mailrooms vs. Canada Post Community Boxes

Lost your mailbox key, just moved in, or worried the last tenant still has a copy? The first question isn't about the lock at all. It's about who owns the box.

In the GTA, most people have one of two kinds:

• A mailroom or lobby mailbox in a condo, apartment building or some townhouse complexes. These belong to the building.
• A Canada Post community mailbox, the grey or silver multi-box units on the street in newer subdivisions in places like Brampton, Vaughan, Markham, Ajax and Oakville. These belong to Canada Post.

The answer changes everything about who can help.

If your box is in a Canada Post community mailbox, a locksmith shouldn't change that lock, and neither should you. The lock and keys are controlled by Canada Post.

For a lost key or a lock problem, contact Canada Post directly. Have your address and box number ready. Expect to show ID and proof of address, and expect that there may be a fee and some waiting time. It's not the fastest process, but it's the right one.

If the box has been damaged or broken into, report it to Canada Post as well. Don't try to pry it open to get your mail.

This is where a locksmith can help, with the building's say-so. Mailroom boxes in condos and rental buildings usually use small cam locks: a little cylinder with a flat metal arm (the cam) on the back that turns to hold the door shut.

Here's how it usually goes:

1. Talk to management or your landlord first. Many buildings have a policy for mailbox locks. Some keep spare keys, some have a preferred locksmith, some need a work order.
2. Get their OK in writing, even an email. A locksmith working in a condo mailroom will want to know the building approved it.
3. Replace or rekey the lock. Cam locks are small and usually quick to swap. The new lock needs to match the cam length and the shape of the arm so it holds the door properly.

Most buildings also need the mail carrier's access to the master door to stay exactly as it is. We only touch your individual box lock, not the building's master lock or the carrier's access.

Some townhouse complexes have their own group mailboxes owned by the condo corporation. Treat those like a mailroom: check with management first.

If you have a mailbox on your own house, like a wall-mounted box with a little lock in an older Toronto neighbourhood, that one's yours. A locksmith can replace the lock or make a key, and you can pick a lock that matches your house key if the mailbox allows it.

When you move into a condo or apartment, you have no idea how many copies of the mailbox key exist. Previous tenants, their family, the cleaner, a past property manager. Mail has bank statements, cheques, cards and IDs in it. Asking management to change or rekey your mailbox lock on move-in is reasonable, and many buildings do it as part of turnover anyway.

If you're a landlord, it's worth adding to your turnover list along with the unit lock. Our post on master key systems for small rental buildings covers how mailroom doors fit into a building's key plan.

If you come home to a mailbox that's been pried open, tell building management and, if mail is missing, contact Canada Post and your bank. Then get the lock replaced. A bent door may need straightening before a new lock will hold.
