What Is an ESA Permit and Why Do You Need One for Electrical Work in Ontario?

The ESA (Electrical Safety Authority) is an independent, not-for-profit organization that oversees electrical safety in Ontario. They administer the Ontario Electrical Safety Code, issue permits for electrical work, conduct inspections, and investigate electrical incidents. Think of them as the governing body that ensures all electrical work in Ontario is done safely and to code.

In Ontario, an ESA permit is required for most electrical work, including: • Electrical panel upgrades or replacements • Adding new circuits or outlets • Rewiring part or all of a home • Installing an EV charger • Generator installation • Hot tub or pool wiring • Any work that involves modifying or extending existing electrical wiring You do NOT need a permit for simple maintenance tasks like replacing a light switch, outlet cover, or light fixture (as long as you're not modifying the wiring).

In Ontario, only Licensed Electrical Contractors (LECs) or homeowners doing work on their own primary residence can pull ESA permits. If you hire an electrician, they should pull the permit on your behalf — this is standard practice. At Taylor G Electric, we include the ESA permit and inspection in every job that requires one. If an electrician tells you a permit isn't needed for significant electrical work, that's a red flag.

After the electrical work is completed, an ESA inspector will visit your home to verify that the work was done safely and to code. They'll check connections, wiring methods, grounding, labeling, and compliance with the Ontario Electrical Safety Code. If everything passes, you'll receive a Certificate of Inspection. If there are deficiencies, the inspector will note them and you'll need to make corrections before a re-inspection.

Skipping an ESA permit might seem like a way to save money, but the consequences can be severe: • Your home insurance may not cover damage from unpermitted electrical work • You could face fines from the ESA • Unpermitted work can complicate or derail a home sale • Most importantly, uninspected work may not be safe The cost of an ESA permit is typically $100–$300 depending on the scope of work — a small price for peace of mind and legal compliance.

We make the permit process seamless. When you hire Taylor G Electric, we pull the ESA permit before starting work, complete the job to code, schedule the ESA inspection, address any deficiencies (though we rarely have them), and provide you with your Certificate of Inspection. You don't have to deal with the ESA at all — we handle everything.
