Am I allowed to add an Ottawa outlet myself?

In Ontario, homeowners are legally permitted to replace an existing outlet (like-for-like), but adding a new outlet requires a licensed electrician and an ESA permit.

This is one of the most common questions we get, and the distinction matters a lot. If your existing outlet is worn out, damaged, or you want to upgrade to a GFCI outlet in a bathroom or kitchen, you can do that yourself — as long as the power is off at the breaker and you're doing a straight swap on the same circuit. No permit required for a simple replacement.

However, adding a new outlet where one doesn't exist is a different story entirely. That work involves running new wiring, connecting to your panel or an existing circuit, and ensuring everything meets the Ontario Electrical Safety Code (OESC). Under Ontario law, this work requires a permit from the ESA (Electrical Safety Authority) and must be performed by a licensed electrical contractor. An ESA inspector will then verify the work before issuing a Certificate of Inspection.

Why does this matter for you as a homeowner? Unpermitted electrical work creates serious problems down the road. If you ever make an insurance claim related to a fire or electrical issue, your insurer can deny the claim if they discover unpermitted work. It also becomes a problem when you sell your home — a home inspection will often flag it, and you may be required to have it corrected at your expense before closing.

The cost to have a licensed electrician add a new outlet in Ottawa typically runs $300 - $600, depending on how far the circuit needs to run and whether your panel has capacity. If a new dedicated circuit is needed, it's toward the higher end of that range. The ESA permit fee is included in what most contractors charge.

If you're replacing an existing outlet yourself, always shut off the breaker first and use a non-contact voltage tester to confirm the power is truly off before touching any wiring. If you open the outlet box and see aluminum wiring (silver-colored, not copper), stop and call a licensed electrician — aluminum wiring requires special handling and approved devices.
