How much does it cost to replace all the outlets in an older Toronto home?

Replacing all the outlets in a typical older Toronto home costs between $2,000 and $6,000 depending on the number of outlets, the type of devices you choose, and whether any wiring issues are discovered during the work. Most older GTA homes — particularly the post-war bungalows and split-levels across Scarborough, North York, and Etobicoke — have anywhere from 30 to 60 outlets, and pricing runs $150 to $300 per outlet installed when you factor in the device, labour, and any minor wiring corrections.

The device cost itself is actually the smallest part of the equation. A standard tamper-resistant receptacle runs $3 to $8, but the labour to remove the old outlet, inspect the wiring connections, replace the device with proper screw-terminal connections, and verify correct polarity and grounding takes a licensed electrician 15 to 30 minutes per outlet. If your electrician discovers aluminum wiring connections, backstabbed (push-in) connections that need to be redone on screw terminals, or deteriorated cloth-insulated wiring inside the boxes, the time per outlet goes up and so does the cost. In older homes throughout the Annex, Riverdale, and High Park, it is very common to find a mix of wiring methods and connection quality that accumulated over decades of previous owners making changes.

Under the Ontario Electrical Safety Code, every new or replaced outlet must now be tamper-resistant — that is the type with the spring-loaded shutters that prevent children from inserting objects into the slots. This is not optional; it is a code requirement across Ontario. If you are replacing outlets in bathrooms, kitchens within 1.5 metres of the sink, garages, outdoors, or unfinished basements, those locations require GFCI protection, which bumps the device cost to $15 to $25 each and the installed cost to $200 to $350 per location. A whole-home outlet replacement project is a smart time to upgrade all required locations to GFCI protection and bring everything up to current code standards.

One important consideration is whether this project requires an ESA permit. If you are doing a like-for-like swap — replacing existing outlets with the same type on existing circuits with no new wiring — a permit is generally not required. However, if the electrician discovers wiring deficiencies that require corrections, or if you are adding GFCI protection where it did not previously exist on circuits that need modification, a permit may be needed. A good electrician will advise you on this during the initial assessment.

Many homeowners doing a whole-home outlet replacement choose to upgrade select locations to USB outlets at the same time, which adds $15 to $30 per device for the outlet itself. The most cost-effective approach is bundling everything into a single project — the electrician is already going from room to room, so adding upgrades at specific locations is far cheaper than calling them back for separate visits later.
