Panel upgrades in Oakville: what to expect
Most homes we open up in Oakville are lakeside older homes and large 1980s–2000s homes. Older houses here are often still on 60 or 100 A services — fine when they were built, tight once you add central air, an EV and an induction range.
Service upgrades in Oakville need a disconnect and reconnect from Oakville Hydro. We file the ESA notification, book the utility, and on the day swap the panel, re-terminate every circuit and test before Oakville Hydro restores power — usually the same afternoon.

Questions from Oakville
How long does a panel upgrade take in Oakville?
Usually one day on site with four to eight hours without power. Booking the Oakville Hydro disconnect typically takes one to three weeks.
Who handles the Oakville Hydro side?
We do. We book the disconnect and reconnect with Oakville Hydro and file the ESA permit — you don't need to call either.
Do all Oakville 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.
