Deviation Requests
When submitting a deviation request, it is important to note there is an associated fee that reflects the time and effort from ESA personnel. This fee is outlined in the ESA Fee Guide.
The ESA Fee Guide can be found here.
For designers, installers or property owners who wish to undertake an electrical installation that deviates from the Ontario Electrical Safety Code (OESC), a formal request is required to be submitted to ESA for review and consideration. The Deviation Request Form must be completed and emailed by the applicant to deviation.request@electricalsafety.on.ca. All further communication for that specific request must be made in response to the related email. Please do not send a new email.
The Deviation Request Form can be downloaded here.
