Service & Panel Upgradesfor Muskoka and the Golden Horseshoe.

Service upgrades are the single most common ask we get. Across Hamilton, Burlington, Dundas, and Ancaster the driver is usually an insurer asking for a Federal Pioneer / Stab-Lok or Sylvania-Zinsco panel replacement, or a homeowner adding an EV charger to a 1970s 100A panel that is already on the edge. Across Muskoka the driver is more often a cottage being converted to four-season use, an upgrade from a 60A or 100A service to support a heat pump or a hot tub, or a new outbuilding needing a sub-panel. The actual work is similar - the planning around utility coordination, ESA scheduling, and load calculation is where contractors with less experience get the timing wrong and homeowners end up without power for a full day longer than they had to be.

A standard 100A-to-200A residential service upgrade is a one-day job when planned properly. The day starts with the utility disconnect (Hydro One, Alectra, Burlington Hydro, Oakville Hydro, or Lakeland depending on the address), the old meter base and service mast come off, the new equipment goes on, the panel inside gets swapped with every branch circuit re-terminated and labelled, the bonding and grounding gets re-done to current code, and the ESA Certificate of Inspection gets scheduled. Power back the same evening in nearly every case. The exceptions are the older properties where the service-entrance conductor itself needs replacement (typically because the original aluminum SE cable has degraded) - those are still one-day jobs but the utility coordination is more involved.

FPE Stab-Lok and Sylvania-Zinsco panel replacements deserve a separate paragraph because they are so common in Ontario and because the insurance angle drives the urgency. Both panel families have documented failure-to-trip records (the FPE issue is the well-known one - the breakers do not always trip on overload, which is the entire point of the breaker existing). Most major Ontario insurers now either refuse coverage or significantly limit it on homes with these panels still in service. Replacement is the only real fix. We pull the ESA permit, swap the panel and the breakers, re-terminate and label every branch circuit, run a continuity check to catch any wires the previous electrician miswired, and close out the ESA inspection. For insurance-clock customers: panel photo to quote inside 48 hours, ESA Certificate of Inspection in your insurer's hands within 10 business days of the swap on a standard like-for-like job. Insurance documentation can be in your hands inside a week.
