How do I verify if electrical work was permitted?

To verify if electrical work was permitted in Ontario, you can check directly with the ESA (Electrical Safety Authority) using their online portal or by calling them at 1-877-ESA-SAFE (372-7233). Most electrical work in Ontario requires permits, and having proper permits protects you legally and ensures insurance coverage.

The easiest way to check is through the ESA's online permit search tool on their website at esasafe.com. You'll need your property address and can search for permits issued within specific date ranges. This will show you all electrical permits pulled for your property, including the permit number, work description, contractor details, and inspection status.

If you're buying a home or inherited electrical work, this verification is crucial. Unpermitted electrical work can void your home insurance if it causes a fire or other damage. Insurance companies regularly check ESA records when processing electrical-related claims. Additionally, unpermitted work may not meet current Ontario Electrical Safety Code standards, creating safety risks.

Common electrical work that requires permits in Ontario includes:

• Panel upgrades or replacements


• New circuits (EV chargers, hot tubs, major appliances)


• Rewiring projects (knob and tube removal, aluminum wiring updates)


• Adding outlets in unfinished spaces


• Generator installations


• Any work involving the electrical service entrance

If you discover unpermitted work, don't panic. You can have a licensed electrician assess the work and apply for a retroactive permit if the work meets code standards. The ESA will inspect it and issue a certificate if everything passes. However, if the work doesn't meet code, it may need to be redone properly.

For work that doesn't require permits - like replacing outlets, switches, or light fixtures on existing circuits - there won't be ESA records. This is normal and legal as long as the work was done safely.

When hiring an electrician, always verify they're ESA-licensed and ask to see the permit before work begins. Licensed contractors through the Ottawa Construction Network automatically handle permitting as part of their service, ensuring your electrical work is legal, safe, and properly documented.
