Panel upgrades in Scarborough: what to expect
Most homes we open up in Scarborough are 1950s–70s bungalows and family homes. Homes of this age commonly have 100 or 125 A services, or a 200 A panel that's simply out of breaker spaces.
Service upgrades in Scarborough need a disconnect and reconnect from Toronto Hydro. We file the ESA notification, book the utility, and on the day swap the panel, re-terminate every circuit and test before Toronto Hydro restores power — usually the same afternoon.
Adding a basement apartment is one of the most common reasons Scarborough homeowners call us about their panel: a second household means a second set of loads, and often a dedicated sub-panel.
Local notes: Scarborough
Basement suites. Many Scarborough bungalows have — or are adding — basement apartments. The electrical has to be designed for two households: separate circuits, interconnected alarms and, often, a sub-panel.
Ageing 1950s–70s wiring. Original wiring in post-war homes is often serviceable but overloaded, with too few circuits for modern kitchens. We add circuits and upgrade services rather than rewiring what doesn't need it.

Questions from Scarborough
How long does a panel upgrade take in Scarborough?
Usually one day on site with four to eight hours without power. Booking the Toronto Hydro disconnect typically takes one to three weeks.
Who handles the Toronto Hydro side?
We do. We book the disconnect and reconnect with Toronto Hydro and file the ESA permit — you don't need to call either.
Do all Scarborough homes need 200 A?
No. If you're only adding an EV charger, load management can often avoid an upgrade. We'll calculate your actual load first.
