Using a Licensed Electrical Contractor

Use the Electrical Safety Authority (ESA) locator to find licensed electrical contractors.


The Electrical Safety Authority (ESA) regulates and promotes electrical safety in Ontario.

As a licensed builder, all electrical work must comply with the Ontario Electrical Safety Code and be performed by a Licensed Electrical Contractor authorized by the Electrical Safety Authority (ESA).

If you are wondering about the Ontario Electrical Safety Code or have other technical questions, the ESA has a comprehensive technical hub to support you and your construction team.
