How Much Does a Panel Upgrade Cost in Ontario?

Typical cost range

For a straightforward residential upgrade, most homeowners in the GTA see quotes in the $2,500 to $4,500 CAD range. That said, no two panels are identical, and the final number depends heavily on what we find once the panel is opened up.

• ✓ Panel size and amperage, moving from 100A to 200A costs more than a smaller step up, since it usually requires larger breakers and heavier wire.
• ✓ Service upgrade needs, if the utility connection (weatherhead, meter base) also needs upgrading to support the new panel, that adds real cost.
• ✓ Wiring condition, older homes with knob-and-tube or aluminum wiring sometimes need remediation work alongside the panel itself.
• ✓ Accessibility, a panel in a cramped crawlspace or behind finished walls takes longer to access and work around than one in an open basement.

Why we don't quote a flat price sight unseen

Anyone who quotes a panel upgrade without seeing the panel first is guessing. We do a proper on-site assessment, including a load calculation, before giving you a firm number. That quote includes the ESA permit and inspection, so there's no surprise fee added later.
