Electricians install, maintain and repair electrical systems in homes and small commercial buildings. Ontario electrical work covers everything from minor repairs (outlets, switches, light fixtures) to major projects: panel upgrades, full rewiring, EV charger installation, knob-and-tube replacement, generator installation, smart home wiring and Electrical Safety Authority (ESA) inspections for permit work.Electricians in Ontario
In Ontario, electrical contracting is regulated by the Electrical Safety Authority. Licensed Electrical Contractors (LECs) hold an Electrical Contractor License, and the work is performed by certified Master Electricians or apprentices supervised by them. Before hiring an electrician from Carpenter Bee or any other source, always verify their ESA license number through the ESA website — it takes 30 seconds and is free. Unlicensed electrical work is illegal in Ontario, voids your home insurance, and creates serious fire and shock hazards.
Browse electrician listings across Toronto, the GTA, Hamilton, Ottawa, London and across Ontario. Each listing shows specialties, service areas, photos and contact details. Carpenter Bee is a classified directory and does not verify licences — that step is on you, and the ESA website makes it simple.
