How much does it cost to install weatherproof outlets around the outside of my house?

Installing weatherproof outdoor outlets around a GTA home typically costs $200 to $400 per outlet, with most homeowners spending $800 to $1,600 to add three or four outlets at key locations. The cost depends on how far each outlet is from your electrical panel, whether your panel has capacity for additional circuits, and how much exterior wall or underground trenching is involved.

The Ontario Electrical Safety Code requires at least one GFCI-protected outdoor outlet at both the front and rear of every home. Many older Toronto homes — especially pre-war houses in neighbourhoods like the Annex, Leslieville, and High Park — were built with no outdoor outlets at all, or have a single unprotected outlet that no longer meets code. Adding proper weatherproof outlets is one of the most practical electrical upgrades you can do, giving you safe power for holiday lights, power tools, electric snow blowers, block heaters, and outdoor entertaining.

Every outdoor outlet must use an in-use weatherproof cover (not the old flip-up style) and be protected by GFCI — either a GFCI breaker in the panel or a GFCI receptacle at the outlet itself. The in-use covers are rated WR (weather-resistant) and seal around the cord while it is plugged in, preventing rain, snow, and ice from reaching the receptacle. The outlet itself should also be a WR-rated (weather-resistant) tamper-resistant receptacle, which is now code-required for all outdoor installations in Ontario. The device alone costs $15 to $30, but the real expense is running the circuit from your panel to the exterior location.

If your electrician can tap into an existing interior circuit that has spare capacity and runs near the exterior wall, a single outdoor outlet addition might cost as little as $200 to $300. However, if a new dedicated circuit needs to be run from the panel — which is common when adding multiple outdoor outlets — expect $350 to $500 per outlet including the GFCI protection, weatherproof box, in-use cover, and wiring. Homes with finished basements or multiple storeys often cost more because the electrician needs to fish wire through finished walls or route conduit along the exterior.

For GTA homeowners planning a deck or patio build, the smartest approach is to rough in outdoor electrical before the decking or hardscaping goes in. Running conduit under a deck or through a patio area is far cheaper during construction than tearing things up afterward. An ESA permit is required for all new outdoor circuits, typically $100 to $200 for residential outlet additions. Need help finding a licensed electrician for outdoor outlet installation?
