How to Find a Licensed Electrician for Panel Work

Panel upgrades in Ontario must be performed by a Licensed Electrical Contractor (LEC) — the ESA's designation for electrical businesses authorized to pull permits. Individual electricians hold a Certificate of Qualification (309A for construction, 309C for industrial). Both credentials are searchable on the ESA's public registry at esa.on.ca. Never hire an electrician who says a permit isn't required for panel work — it always is. (Serving Markham, Ontario.)
