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 electrical contractor
• All materials needed to complete the job to Ontario Electrical Safety Code (OESC) standards

There are no hidden material costs or permit surcharges when you get a full-price quote from a reputable contractor.

Why Does Service Type (Underground vs. Overhead) Affect Cost So Much?

The difference between underground and overhead service upgrades comes down to scope of work:

• Underground service — The utility line enters through the foundation. The contractor replaces the meter base and panel without working on the exterior of the roof or upper walls. Less labour, lower cost.
• Overhead service — The line enters through a weatherhead mounted near the roof. Replacing the service requires new service entrance cable running along the exterior of the house, a new weatherhead, and a utility disconnect so Hydro can reconnect your service after the work is done. More labour, materials, and coordination mean a higher price.

What Affects the Final Cost?

Beyond panel size and service type, a few other factors can affect your final quote:

• Number of circuits — More circuits mean more breakers to transfer and more time on the job.
• Panel location — A panel in a finished basement or tight utility room takes longer to access safely.
• Condition of existing wiring — If the inspector finds code violations in your existing wiring during the ESA inspection, corrections will be required before the permit is closed.
• Aluminum wiring — Homes with aluminum branch circuit wiring require special handling at connections, which may add time.

Do I Need a Permit to Replace My Electrical Panel in Ontario?

Yes — always. Under Ontario’s Electrical Safety Code (OESC) and ESA regulations, replacing or upgrading an electrical panel is a regulated activity that requires a permit. The permit triggers an ESA inspection after the work is complete, which protects you as the homeowner and is required for insurance and resale purposes.

Be cautious of any contractor who offers to skip the permit to save money — this is illegal in Ontario and can void your home insurance, create problems when you sell, and leave your family at risk from uninspected electrical work.

When Should You Replace Your Electrical Panel?

You should consider panel replacement or upgrade if:

• Your panel is a recalled brand (Federal Pacific, Zinsco, or older Canadian brands)
• Breakers trip frequently or fail to reset
• You’re adding major appliances (EV charger, hot tub, central AC)
• Your home still has a 60-amp or 100-amp panel and you want to add circuits
• Your insurance company is flagging the panel as a liability
• You’re renovating and need additional capacity
