Preparing for Your Inspection
ESA is responsible for monitoring and enforcing compliance with the Ontario Electrical Safety Code. Inspections are there for the safety of you and your family to help ensure electrical work complies with the Code.
The documents below give a broad overview of what you can expect to be inspected during the different stages of electrical work. They do not constitute the entirety of the Ontario Electrical Safety Code and its application. They do not constitute advice on how to do electrical work and should not be used as a substitute for the services of a qualified licenced electrical contractor. Information may not be applicable to your specific situation.
ESA inspections are limited to the electrical installation, product or device described in the notification. Depending on the nature of the installation, an Inspector may look at all or only some of the above elements. An Inspection does not in any way relieve the applicant from their responsibility to comply with the Ontario Electrical Safety Code in all aspects of their work and the installation.
Note: Under the Ontario Electrical Safety Code, the Electrical Safety Authority determines which installations to inspect. ESA may accept installations and issue connection authorizations without conducting inspection.
