Electrical Inspection

Know your obligations under the law!

Planning a renovation? Updating the kitchen or bathroom? Adding new lighting? If your project involves new electrical wiring or devices, or repairing/replacing old ones, you need to know your obligations under Ontario law.

alert Please be advised only an authorized Toronto Hydro employee or a qualified Toronto Hydro contractor working on behalf of Toronto Hydro can disconnect or reconnect services. This includes any disconnection at the meter. Toronto Hydro must be contacted to arrange for any disconnection or reconnection prior to commencement of customer work.

Whether you’re doing the work yourself, or hiring a licenced electrical contractor, in most cases you will need a permit and an electrical inspection to ensure the work complies with the Ontario Electrical Safety Code.

Take these steps to ensure a safe and successful electric project

  • Follow the Ontario Electrical Safety Code
  • Take out a permit
  • Get your project inspected
  • Hire only licenced electrical contractors

The Electrical Safety Authority (ESA) is responsible for conducting electrical inspections in Ontario.

If you’re doing the work yourself, be sure to allow for the appropriate time in your schedule for permits and inspections. Also remember that any electrical work must be visible to the ESA inspector at the time of inspection. So, for example, do not drywall over a wall that has new electrical work.

To learn more about inspection requirements, permits and fees please visit the ESA website.

Hire a licenced contractor

ESA strongly recommends hiring a licenced electrical contractor. This ensures that the company you have hired:

  • is fully insured
  • uses qualified electricians to perform the electrical work
  • will arrange for permits with the ESA
  • can deliver an ESA Certificate of Inspection

ESA has a searchable database to help you locate a licenced electrical contractor near you.

More complex than you think

While you may regularly tackle home improvement projects, it’s important to remember that electrical work can be very complex. Making a mistake can result in deadly fires or a severe shock.

General handymen and other service providers cannot legally do electrical work in homes unless they hold a licence. If you hire a general contractor, confirm that the electrical work will be done by a licenced subcontractor. Licenced electrical contractors are required to display their ESA/ECRA licence number on their work vehicle and on any paperwork such as invoices or estimates. Ask to see it. How to spot an unlicenced contractor.

Disconnecting from Toronto Hydro

There may be times when you need to completely disconnect your service from the Toronto Hydro distribution network.

Disconnections and reconnections can be done only by an authorized Toronto Hydro employee or an authorized Toronto Hydro contractor. You or your electrical contractor cannot perform this service.

For complete details and contact information about applying to disconnect and reconnect your service, please see our Service Disconnections FAQ page.
