Electrical panel upgrades are now driven by three things: EV chargers, heat pumps, and safety compliance. This thread covers 2026 costs and what Ontario homeowners need to know about permits.
Why GTA Homes Need Upgrades Now
Homes built before 1980 commonly have 60-amp or 100-amp panels. A Level 2 EV charger alone requires 40-50 amps dedicated. Heat pumps add another 30-60 amp load. Knob-and-tube or aluminum branch wiring creates insurance issues and fire risk - many Ontario insurers now require remediation before coverage.
Panel Upgrade Costs 2026
- 100A to 200A: $2,500-$4,500 installed
- 200A to 400A (large home, EV + heat pump): $4,000-$8,000
- Subpanel (garage, addition): $800-$2,000
- ESA permit: $200-$400
- Hydro One/Toronto Hydro service upgrade (if required): $500-$2,000 additional
ESA Permit Process
All panel work in Ontario requires an ESA permit and inspection. Licensed electrical contractor required - no DIY panel work. ESA inspection sign-off triggers meter upgrade from the utility if service size increases.
