Common Myths About Electrical Permits and Inspections

The Ontario electrical permit system has more misinformation around it than almost any other part of home ownership. Bad advice on Reddit, contractors cutting corners, and the confusion between city building permits and ESA notifications add up to homeowners taking real risk without realizing it. Here are the myths worth killing.

Myth 1: “Small jobs don’t need a permit.”

Wrong. Under the Ontario Electrical Safety Code (OESC), adding a single outlet, running a new circuit, or extending existing wiring all require an ESA notification of work. The size of the job does not decide — the change to the wiring does. Only true like-for-like device swaps on modern grounded wiring skip the notification.

Myth 2: “A building permit covers electrical.”

Two different systems. Your city or municipality issues building permits for structural, occupancy, and framing work. The Electrical Safety Authority (ESA) issues electrical notifications and inspects the wiring. A renovation typically needs both, filed separately. Skipping the ESA side because you have a city permit is a common and expensive mistake.

Myth 3: “If it works, it’s safe.”

The single most dangerous assumption in DIY electrical work. A back-stabbed receptacle, undersized wire, or missing bond can operate fine for years and then arc-fault behind drywall. Inspection catches these before they become insurance claims — or fires.

Myth 4: “My contractor said we can skip the permit to save money.”

Any contractor who suggests skipping the ESA notification is either not a Licensed Electrical Contractor (LEC), not carrying real liability insurance, or both. The ESA fee is small — minimum $88 for residential in 2026. What you are actually being sold is exposure. If they will lie to ESA about a permit, they will cut corners on your wiring too.

Myth 5: “Unpermitted work never gets discovered.”

It gets discovered constantly — at closing. Real estate lawyers ask for Certificates of Acceptance. Home inspectors flag panels that do not match ESA records. Insurers investigate after fire and water damage claims. “Nobody will find out” holds up until you try to sell, refinance, or file a claim.

Myth 6: “Homeowners can’t do any electrical work themselves.”

Partly wrong. In Ontario you can file a homeowner notification and do work in your own primary residence, as long as you meet OESC compliance and the ESA inspector on site. You cannot pull a homeowner permit for a rental, income property, or your parent’s house. And you still get inspected.

Myth 7: “A certified electrician is the same as a Licensed Electrical Contractor.”

Not in Ontario law. A 309A certified electrician can perform work as an employee of an LEC. Only a Licensed Electrical Contractor with an ECRA/ESA business licence can be hired to do the work and file the notification. Paying an individual electrician on the side means no permit and no inspection.

Myth 8: “Permits slow the job down for no reason.”

Residential inspections are typically scheduled within a few business days and take under an hour on site. The delay is small — the protection is not. And on jobs like a panel upgrade or service upgrade, the utility often will not energize the new service without ESA sign-off anyway.

Myth 9: “I can pull the permit after the drywall goes back up.”

Notifications must be filed before, or within 48 hours of, the work starting. Larger jobs also require a rough-in inspection before the walls close. Trying to backfill a permit after the fact often means opening walls back up for the inspector.

Bottom Line

Ontario’s permit and inspection system is not paperwork for its own sake. It is what makes electrical work insurable, resellable, and legally recognized. Hire an ECRA/ESA Licensed Electrical Contractor, confirm the notification is filed, and keep the Certificate of Acceptance with your records.
