How Much Does an Electrical Panel Upgrade Cost in Ontario? (2024 Guide)

If your home was built before 1990, there is a good chance your electrical panel is overdue for an upgrade. The average cost of an electrical panel upgrade in Ontario ranges from $2,000 to $4,500 depending on the scope of work.

Here is a quick breakdown of what most homeowners pay:

A 100-amp to 200-amp upgrade typically runs $2,500 to $4,500. A fuse box to breaker panel conversion costs $2,000 to $3,500. A panel replacement (same amperage) is usually $1,800 to $2,800. Adding a subpanel runs $800 to $1,500.

These prices include the ESA permit and inspection, which is required by law in Ontario. Any electrician who skips this step is cutting corners you do not want cut.

Most older homes in Brampton and across the GTA have 100-amp panels. That was plenty when houses had a stove, a few lights, and maybe a window air conditioner. Today, you are running central air, multiple TVs, computers, kitchen appliances, and possibly an EV charger or hot tub.

A 100-amp panel can handle basic household needs. A 200-amp panel gives you the headroom for modern living, including high-draw additions like EV chargers, hot tubs, home workshops, and electric heating.

If you are just replacing an aging panel and your electrical needs have not changed much, 100 amps may be fine. But if you are adding an EV charger, finishing a basement, or planning any major renovation, go with 200 amps. The incremental cost of upgrading to 200 amps during the project is much lower than doing it separately later.

When you get a quote for a panel upgrade, make sure it includes all of these items. If it does not, ask why.

A proper panel upgrade includes removal of the old panel and installation of the new one, the new breaker panel and all circuit breakers, reconnection of all existing circuits, ESA permit application and inspection fee, the ESA certificate of inspection, and cleanup of the work area.

Some panel upgrades end up costing more than expected because of issues discovered during the work. Here are the most common ones.

Your meter base may need replacing. If your utility meter base is old or incompatible with a 200-amp panel, Alectra Utilities may require a new meter base. This adds $500 to $1,200 to the project. Your local utility handles the meter swap, but you pay for the base itself.

Your home may need additional circuits. If your panel is outdated, some circuits may not meet current code. Your electrician might recommend adding dedicated circuits for your kitchen, bathroom, or laundry. Each new circuit adds $200 to $400.

Aluminum wiring or knob-and-tube wiring may need attention. If your home has outdated wiring, the panel upgrade is the right time to address it. Insurance companies often require this work as a condition of coverage.

Yes. A panel upgrade is one of the best investments you can make in your home. Here is why.

Safety comes first. An outdated panel with worn breakers is a fire risk. Modern panels with arc-fault and ground-fault breakers catch problems before they become dangerous.

Your insurance may require it. Many Ontario insurance companies charge higher premiums for homes with outdated panels or fuse boxes. Some refuse coverage entirely. Upgrading can lower your premiums.

Home value increases. A 200-amp panel upgrade is a selling point that home buyers and inspectors look for. It signals that the home's electrical system is modern and safe.

You need it for modern additions. EV chargers, hot tubs, central air, and home offices all require significant electrical capacity. Without a panel upgrade, you cannot safely power these additions.

Get at least two quotes from ESA-licensed electricians. Make sure each quote includes the same scope of work so you are comparing apples to apples.

Ask about bundling. If you need other electrical work (pot lights, wiring updates, EV charger prep), doing it all during the panel upgrade saves money because the electrician is already on site.

Do not choose the cheapest quote if it does not include the ESA permit and inspection. That is a non-negotiable requirement in Ontario. Any electrician who offers to skip the permit is not someone you want working on your home.
