100-amp to 200-amp service upgrades, usually done in one day — ESA permit and utility coordination handled for you.
Planning an EV charger, a hot tub, or a renovation in East Gwillimbury? Most of those projects start at the panel. We upgrade 100-amp services to 200 amps across East Gwillimbury, with permits and inspection handled end to end.
Your panel is the heart of your home's electrical system. When it is undersized, everything you add — a charger, a hot tub, a legal basement suite — fights for the same limited capacity. A 200-amp service ends the fight and quietly raises what your home can do for decades.
Newer subdivisions in East Gwillimbury usually start at 100 or 200 amps, but builder panels fill up fast once a charger, air conditioning and a finished basement land. We calculate the real load and upgrade the service or panel so everything can run at once — no nuisance trips.
We are based in Aurora, a short drive from East Gwillimbury — most quotes go out the same day, and East Gwillimbury jobs get priority scheduling. Every upgrade includes a load calculation before we quote, the ESA notification and inspection, and a clean, labelled, photo-documented finish — the same standard behind our 5.0-star rating across 68 Google reviews.

It depends on your current service size, meter and mast condition, and your local utility's requirements. Most quotes are straightforward once we see photos of your panel and meter base — send them over and we will price the exact job, free, with the load calculation shown. No invented numbers, no surprises on install day.
Most upgrades are completed in a single day. Power is off for part of that day while the service is swapped; we coordinate the disconnect and reconnect with your local utility so the window is as short as possible, and your home is powered back up before we leave.
Yes. A service or panel upgrade requires an ESA electrical notification and an inspection, and the work must be done by a licensed electrical contractor. We arrange the notification, complete the work to the Ontario Electrical Safety Code, coordinate with the utility, and meet the inspector.
Not always — it depends on your home's total load, which is why every charger quote starts with a load calculation. If your East Gwillimbury panel is full or your service is undersized, an upgrade (or charger load management) comes first. See our page on EV charger installation in East Gwillimbury for how the two projects fit together.
In most cases, yes. Fuse panels are at the end of their service life, many insurers require or strongly prefer modern breaker panels, and a fuse box leaves no room for today's loads. A replacement brings you modern breakers, proper grounding and bonding, and breaker space for future projects.
Every job starts with a clear, honest quote. Send the details and photos of your panel or project — we’ll take it from there.
