Doing Electrical Work
Who can do electrical work at my property?
Electrical work is complicated and mistakes can be serious. If you hire someone to do electrical work in your home, by Ontario law, they must be a Licensed Electrical Contractor (see exceptions*). Licensed Electrical Contractors are trained in and understand the safety requirements associated with electrical installations.
General service providers cannot do electrical work in residences unless they hold an electrical contractor’s licence. If you hire a general contractor, confirm that a licensed subcontractor will do the electrical work. A Licensed Electrical Contractor must display their licence number. Ask to see it.

Electrical work can also be done in a home by the homeowner or occupant.

If you choose to do the work yourself, be aware of the responsibilities and risks. Ensure the work is done according to the Ontario Electrical Safety Code and file all required notifications of work to ESA.
