2026 pricing guide — average costs, what's included, and what affects your quote in Ontario.
Get a Free QuoteUpgrading from a 100 amp to a 200 amp electrical panel in Ontario typically costs between $1,800 and $3,500, with most GTA homeowners paying around $2,500. This upgrade is one of the most common electrical projects in older Toronto-area homes — especially those built before the 1990s that were originally wired for lower electrical demand.
The work requires an ESA permit in Ontario. Kolji Bros. handles the permit application and coordinates the mandatory ESA inspection as part of every upgrade.
Cost to Upgrade from 100 Amp to 200 Amp Panel Costs
Costs vary based on panel location, whether a new meter base is needed, and utility disconnect fees:
| Service Type | Typical Cost (GTA) | Notes |
|---|---|---|
| Panel upgrade only (accessible location) | $1,800 – $2,400 | Standard installation, no relocation |
| Panel upgrade + new meter base | $2,200 – $3,000 | Often required by utility company |
| Panel upgrade + service entrance replacement | $2,500 – $3,500 | Full service upgrade from street |
| ESA permit & inspection | $150 – $300 added | Mandatory in Ontario |
What Affects the Cost of a 100–200 Amp Upgrade?
Several variables influence your final price. Here's what matters most:
Panel Location
Panels in finished basements or tight spaces take longer to access, increasing labour costs.
Existing Service Entrance
If the wires from the street are undersized, they'll need upgrading too — adding $300–$800.
Meter Base Condition
Older meter bases often need replacement to accept 200A service.
Utility Coordination
Toronto Hydro or Alectra must disconnect and reconnect power — scheduling adds time.
ESA Permit
Required for all panel work in Ontario. Typically $150–$300.
GTA Location
Toronto core labour rates run ~10–15% higher than suburban GTA.
