Generator installation in Toronto: what to expect
Outages in Toronto come with ice storms and summer thunderstorms. Even a few hours without power matters if your basement relies on a sump pump or someone at home relies on medical equipment.
We size the generator from a load assessment — essential circuits only, or the whole home — install the automatic transfer switch, and coordinate the gas connection with a licensed gas fitter.
Prefer a portable generator? A properly installed inlet and interlock lets you power the panel safely, without dangerous back-feeding into Toronto Hydro's lines.
Local notes: Toronto
Toronto Hydro coordination. Service upgrades in the city need a disconnect and reconnect from Toronto Hydro, and some older overhead drops need upgrading on their side too. We book it and tell you upfront if their work will affect the timeline.
Laneway and garden suites. Toronto now permits laneway and garden suites on many lots. Feeding power to a backyard building usually means a new service or a sub-feed from the main house — a load calculation comes first.
