Estimates for a small start in Canada, not guarantees.

What it is

You supply and install mailboxes for houses: post-mounted rural boxes, wall-mounted boxes and replacements for damaged or tired ones. You also repair posts and fit new house numbers.

Your first three steps

  1. Read Canada Post's current guidance on mailbox types and placement, then pick 5 to 10 products that meet it
  2. Open a trade account with a hardware wholesaler or mailbox manufacturer and price a few standard install packages
  3. Offer installs to neighbours, local renovators and property managers, and ask for photos and reviews
Who pays

Homeowners, landlords, small builders and renovators, and property managers looking after several buildings.

How it makes money

You mark up the mailbox and materials, then charge a fixed price or hourly rate for installation. Some jobs add extras like house numbers, concrete footings or a new post.

Skills that help
  • Basic carpentry and fixing skills
  • Measuring and neat finishing
  • Friendly customer service
Watch out for
  • Canada Post rules on box type, height and location, which vary by address, so check before you install
  • New developments and some buildings use Canada Post community mailboxes, so those jobs may not be yours to do
  • Call your provincial locate service before digging post holes to avoid buried utilities
  • Commercial general liability insurance
  • Frozen ground and snow in winter limit post installs, so plan for slower months
  • Check your provincial rules on GST/HST registration once revenue passes the small supplier threshold
