Every panel upgrade in Ontario needs a permit. There are no exceptions for “just a small swap,” “same amperage,” or “my brother-in-law is an electrician.” The Ontario Electrical Safety Code and the Electrical Safety Authority both require notification and inspection on any change to a home’s main service panel, and the utility will not reconnect the service after a swap without the ESA’s release. This guide walks GTA homeowners through when a permit is required for a panel upgrade, what the permit covers, and how the process works from filing to reconnection.
Direct answer: any change to your home’s electrical service panel requires an ESA (Electrical Safety Authority) permit in Ontario. Panel replacement, service upgrade from 60/100 to 200 amp, panel relocation, and even a like-for-like brand swap all require a filed notification and an inspection before the utility will reconnect service.
Direct answer: Ontario offers two paths for a residential permit. A homeowner doing the work themselves files an ESA Homeowner Wiring Notification (available online through esasafe.com). A licensed electrical contractor files the same notification under their own contractor number as part of their engagement. Either way, ESA is notified before the work starts and inspects before the utility reconnects.
Homeowners cannot legally hire an unlicensed person to do panel work in Ontario, and they cannot file a Homeowner Wiring Notification on someone else’s behalf. The only two legal paths are DIY-with-your-own-permit or hire-a-licensed-contractor.
Direct answer: some homeowners hear stories of neighbours who “just did the panel swap” without a permit. Those stories usually leave out three details — (1) the neighbour cannot legally sell the home without disclosing the unpermitted work, (2) their insurance policy is voidable, and (3) if the panel is ever inspected during a real estate transaction, the buyer’s condition of purchase almost always requires a new ESA-permitted replacement.
The Electrical Safety Authority lists unpermitted panel work under its residential incident categories in the Ontario Electrical Safety Report. The permit fee is minor compared to the downstream costs of skipping it.
Direct answer: the ESA permit fee for a residential panel upgrade in the GTA is $95-160 depending on scope and whether it is homeowner-filed or contractor-filed. Contractor-filed permits are usually bundled into the total project quote so homeowners do not see it as a line item.
Utility coordination is separate. Toronto Hydro charges no fee for a scheduled residential disconnect; Alectra charges $75-150; Hydro One charges vary by rural area. Contractors typically include utility coordination in their quote.
In our experience filing panel upgrade permits across the GTA, the fastest way to avoid delays is bundling everything the utility might touch into the same permit. If you are already upgrading to 200 amp, consider adding an EV charger, a subpanel for a finished basement, or a whole-home surge protector on the same permit and the same day. The utility disconnects once, the ESA inspects once, and you get all the electrification you were planning within one project. Homeowners who upgrade the panel today and add the EV charger next spring end up scheduling two utility disconnects and paying for two ESA inspections — avoidable with a bit of upfront planning. Our post on whether you need a panel upgrade covers the pre-upgrade decision points.
