Toronto’s electrical systems span more than a century — from knob-and-tube wiring in early 1900s homes to smart panels in new condos. Whether you’re upgrading a 60-amp panel in Leslieville or wiring a basement suite in North York, all electrical work must be performed by a licensed electrician with a valid Ontario Certificate of Qualification.

GTA Trades Daily connects you with licensed, insured, reviewed electricians serving Toronto who handle residential and light commercial electrical work across the city.

What Toronto Homeowners Need to Know About Electrical

Knob-and-Tube Wiring

Homes built before 1950 often contain knob-and-tube wiring. Most Ontario insurance companies will not insure homes with active knob-and-tube unless it is removed or fully replaced.

Aluminum Wiring

Homes built between 1950 and 1980 may have aluminum wiring. It is legal but requires approved connectors at every junction. Improper connections are a major fire risk.

Panel Capacity

Many older Toronto homes still run on 100-amp service. Modern electrical loads — EV chargers, heat pumps, home offices — often require a 200-amp upgrade.

ESA Permits

All electrical work in Toronto requires an ESA (Electrical Safety Authority) notification and inspection. There are no exceptions.

Toronto Hydro Coordination

Any work involving the meter base or service entrance requires coordination with Toronto Hydro. Your electrician handles this during panel upgrades or service changes.
