How Much Does a Panel Upgrade Cost in Ontario?
If your home still runs on a 60A or 100A fuse panel, you鈥檝e probably wondered what it costs to upgrade 鈥� and why it matters. Here鈥檚 a straightforward breakdown.
What affects the price
- Service size 鈥� moving from 100A to 200A costs less than jumping to 400A for a large home or addition.
- Underground vs. overhead service 鈥� underground connections typically start around $2,200, while overhead connections start around $2,500.
- Panel location and accessibility 鈥� older homes with panels in tricky spots may require more labour.
- Permit and inspection fees 鈥� every legal panel upgrade includes an ESA permit and final inspection, which is factored into your quote.
Signs you may need an upgrade
- Frequent breaker trips or blown fuses
- Flickering lights when appliances turn on
- Planning to add an EV charger, hot tub, or home addition
- Your panel still uses fuses instead of breakers
