What is the ESA Certificate of Inspection and why should I keep it?

The ESA Certificate of Inspection is the official document confirming that permitted electrical work in your home has been inspected and meets the Ontario Electrical Safety Code — and it is one of the most important documents a homeowner can have. Think of it as the electrical equivalent of a clean bill of health. Every time a licensed electrician completes permitted work and the ESA inspector approves it, a certificate is issued.

The certificate contains specific details: the date of inspection, the address, the scope of work that was inspected, the permit number, and the inspector's determination that the installation complies with the OESC. It is issued by the Electrical Safety Authority after the inspector physically visits your property, examines the work, verifies code compliance, and confirms that everything is safe. If there were deficiencies that required correction, the certificate is only issued after the corrections pass re-inspection.

You should keep every ESA Certificate of Inspection you receive for as long as you own the home — and ideally pass them to the next owner when you sell. Here is why they matter in practical terms for GTA homeowners.

Insurance claims are the most critical reason. If an electrical fire occurs and your insurer investigates, one of the first things they look for is whether the electrical system was properly permitted and inspected. If recent electrical work was done without a permit — no certificate — the insurer may deny your claim, potentially leaving you liable for hundreds of thousands of dollars in damage. Ontario insurers have become increasingly strict about this, particularly for older Toronto homes where knob-and-tube remediation, panel upgrades, and rewiring are common.

Home sales are the second major reason. Toronto real estate lawyers routinely request ESA certificates for any electrical work done in the last 10 to 15 years. Buyers' home inspectors flag recent electrical modifications and ask for proof of permitting. Having your certificates organized and available speeds up the closing process and gives buyers confidence. Missing certificates on recent panel upgrades, rewires, or EV charger installations raise red flags that can delay or derail a sale.

Future electrical work benefits from having past certificates on file. When your electrician pulls a new permit for additional work, the ESA's records show the history of inspected work at your address. This gives both your electrician and the inspector a clear picture of your home's electrical system, making the permitting and inspection process smoother.

If you have lost a certificate, you can request a copy from the ESA. They maintain records of all inspections and can provide duplicate certificates, though there may be a small administrative fee. You can also check the status of permits at your address through the ESA's online lookup tool at esasafe.com.
