How Much Does It Cost to Replace an Electrical Panel in Ontario?

If your home’s electrical panel is old, overloaded, or failing, replacing it is one of the most important investments you can make in your property. But before you call a licensed electrical contractor, you want to know what to budget. In Ontario, electrical panel replacement costs vary based on panel size, service type, and the complexity of your existing wiring — but this guide gives you real numbers so you can plan with confidence.

What Does Electrical Panel Replacement Cost in Ontario?

All prices below include labour, materials, and the required ESA (Electrical Safety Authority) permit. In Ontario, only a licensed electrical contractor is legally permitted to replace an electrical panel and pull the necessary permit.

100-Amp Panel Replacement

Replacing a 100-amp panel in a residential home typically costs $1,200 to $1,400, depending on how many circuits are in the existing panel. Homes with more circuits require more time and materials to transfer and inspect each breaker.

200-Amp Panel Replacement (Same Service Size)

If your home already has 200-amp service and you’re simply replacing the panel box, expect to pay starting from $1,500. This covers the new panel, breakers, labour, and permit.

200-Amp Service Upgrade (Underground Service)

Upgrading your home from 100-amp to 200-amp service with an underground service entrance starts at $1,600. Underground services are generally less complex because the service cable runs underground without the need for overhead weatherhead work or utility pole coordination.

200-Amp Service Upgrade (Overhead Service)

Upgrading to 200-amp service with an overhead service entrance starts at $2,600. Overhead services involve replacing the weatherhead, service entrance cable, and coordinating a utility disconnect with your local hydro company — all of which add time and cost to the project.

What’s Included in the Price?

When you hire a licensed electrical contractor in Ontario for a panel replacement, the quoted price typically covers:

• New electrical panel and breakers
• All required wiring connections and circuit transfers
• ESA permit application and inspection
• Labour by a licensed master electrician or contractor
• All materials to OESC standards

Why Service Type Affects Cost

• Underground service — Line enters through foundation. No roof work or weatherhead. Less labour, lower cost.
• Overhead service — Line enters through weatherhead at roofline. New service entrance cable, weatherhead, and utility disconnect needed. More labour = higher cost.

When Should You Replace Your Electrical Panel?

• Panel is a recalled brand (Federal Pacific, Zinsco)
• Breakers trip frequently or fail to reset
• Adding EV charger, hot tub, or central AC
• Home still has 60- or 100-amp panel
• Insurance company flagging the panel
