Safety Warnings

NEVER attempt DIY electrical work. Electrocution can kill instantly. Ontario law requires ESA-licensed electricians for all electrical work.
If you experience flickering lights, burning smells, warm outlets, or frequent breaker trips, call a licensed electrician immediately. These are signs of dangerous wiring.
If you discover previous DIY electrical work in your home, have it inspected by an ESA-licensed electrician before using those circuits.
Water and electricity are a lethal combination. Never touch electrical panels, switches, or outlets with wet hands or while standing in water.

What You Need to Know

Understand Ontario electrical law

Under the Ontario Electrical Safety Code, virtually all electrical work must be performed by a Licensed Electrical Contractor (LEC) registered with the Electrical Safety Authority (ESA). This is not a suggestion — it is the law.

Know what homeowners CANNOT do

Homeowners cannot legally install new circuits, upgrade panels, add outlets, install light fixtures on new circuits, or do any work that requires a permit. Even changing a light switch in some cases requires a licensed electrician.

Know what homeowners CAN do

You may replace existing light bulbs, plug in appliances, and replace existing wall plates. Some jurisdictions allow homeowners to replace existing switches and outlets on existing circuits, but an ESA inspection is still recommended.

Why DIY electrical work is dangerous

Improper wiring causes over 1,000 house fires in Ontario annually. Electrical shock can be fatal. DIY electrical work can void your home insurance, fail home inspections, and make your home unsellable.
