Panel upgrades in Newmarket: what to expect
Most homes we open up in Newmarket are 1970s–90s subdivisions around a historic Main Street. 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 Newmarket need a disconnect and reconnect from Newmarket-Tay Power Distribution. We file the ESA notification, book the utility, and on the day swap the panel, re-terminate every circuit and test before Newmarket-Tay Power Distribution restores power — usually the same afternoon.
Adding a basement apartment is one of the most common reasons Newmarket homeowners call us about their panel: a second household means a second set of loads, and often a dedicated sub-panel.
Local notes: Newmarket
Main Street heritage. Older houses and storefronts around Main Street South can have dated wiring and small services.
1980s–90s subdivisions. Homes in Glenway and Armitage are prime for basement finishing and kitchen renovations — often with a panel that's already full.

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