What Is an ESA Inspection?

The Electrical Safety Authority (ESA) is responsible for enforcing the Ontario Electrical Safety Code and ensuring electrical work is completed safely.

An ESA inspection allows a licensed inspector to verify that electrical installations meet current safety requirements before the work is approved.

Quick Answer

Most new electrical installations, service upgrades, EV charger installations, and major renovation projects require an ESA permit and inspection in Ontario.

When Is an ESA Inspection Required?

Many electrical projects require notification to the ESA before work begins. Common examples include:

Electrical panel upgrades
100 amp to 200 amp service upgrades
EV charger installations
Generator installations
Finished basement wiring
New circuits and subpanels
Home additions and major renovations

"Most homeowners never interact directly with the ESA because their licensed electrical contractor handles the permit and inspection process."

Who Obtains the ESA Permit?

In most cases, the licensed electrical contractor performing the work obtains the ESA permit and coordinates inspections as part of the project.

Homeowners performing their own electrical work may also obtain permits directly, but they remain responsible for ensuring the installation complies with Ontario Electrical Safety Code requirements.

What Happens During an ESA Inspection?

The inspector reviews the electrical installation to verify it complies with current code requirements and safety standards.

Depending on the project, inspections may occur before walls are closed, after equipment installation, or upon project completion.

What Happens If Electrical Work Is Not Inspected?

Unpermitted electrical work may create safety concerns, insurance complications, and difficulties during future home sales. In some cases, homeowners may be required to correct deficiencies before obtaining final approval.

How Do You Know If Your Project Needs an ESA Inspection?

The safest approach is to consult a licensed electrical contractor before starting any significant electrical project. An experienced electrician can determine whether a permit is required and handle the inspection process on your behalf.
