Why is ESA a separate inspection from my Toronto Building permit?

Electrical safety in Ontario is regulated separately from building permits under the Electricity Act, 1998 and Ontario Regulation 570/05, the Licensing of Electrical Contractors and Master Electricians Regulation, with the Electrical Safety Authority (ESA) as the delegated administrative authority. Every piece of electrical work — new circuits, panel upgrades, knob-and-tube replacement, EV chargers, basement legalizations, hot-tub feeds, even most light-fixture relocations — requires a notification of work filed with ESA by a Licensed Electrical Contractor (LEC) before energization. Toronto Building's permit covers the structure; ESA's notification covers the wiring, and the two reviews run on parallel tracks.

The LEC files the notification online, ESA assigns a permit number, the contractor completes the rough-in to the Ontario Electrical Safety Code (28th edition, based on CSA C22.1 with Ontario amendments), and ESA inspects rough wiring before drywall closes. After devices, panels, and final connections, ESA returns for a final inspection and issues a Certificate of Inspection (formerly called the ESA sticker). Toronto Building will not close the building permit on any scope that included electrical work without that Certificate on file. On panel-upgrade and full-rewire projects, Toronto Hydro's service connection coordination adds another layer — ESA inspects, then issues the Connection Authorization that Toronto Hydro requires before reconnecting the meter.

Timeline is 2 to 6 weeks of inspection scheduling beyond the build itself, longer in peak summer and during major-storm response periods when ESA inspectors are reassigned. Fees are paid by the LEC and passed through — typical residential renovation notifications run CAD 200 to 900 depending on circuit count and panel size. Two homeowner-facing rules: never accept work from an unlicensed electrician (verify the ECRA/ESA licence number on the ESA Contractor Look-Up before signing), and never let a renovation reach drywall without the rough-in inspection sign-off in writing. Working without a notification is a provincial offence and can void homeowners' insurance after a fire.
