How much does it cost to replace a fuse box with a breaker panel in Toronto?

Converting a fuse box to a modern circuit breaker panel in the GTA typically costs $2,500 to $4,500, depending on whether the service entrance and meter base also need upgrading. This is one of the most common electrical projects in older Toronto neighbourhoods, and it is almost always worth the investment for safety, convenience, and insurance compliance.

Fuse boxes are found in homes built before the mid-1960s, particularly in established Toronto neighbourhoods like the Annex, Cabbagetown, Riverdale, High Park, Leslieville, and the older parts of Scarborough and Etobicoke. Most of these fuse boxes are rated at 60 amps, which was adequate when homes had a few lights, a refrigerator, and maybe a window air conditioner. Today, with central air conditioning, multiple kitchen appliances, home offices, EV chargers, and entertainment systems, 60 amps is dangerously insufficient. The fuse box itself is also a concern because homeowners often install higher-rated fuses to stop them from blowing, which allows wires to carry more current than they are rated for and creates a hidden fire hazard inside the walls.

The conversion process involves removing the old fuse box and installing a new 200 amp breaker panel in its place. In most cases, the service entrance cable running from the meter to the panel also needs replacement because the original cable is only rated for 60 or 100 amps. Your electrician will coordinate with Toronto Hydro for a temporary disconnect, which typically requires five to ten business days' advance notice. The meter base on the exterior of your home may also need replacement if it is the original equipment. A straightforward fuse box to breaker panel swap where the service entrance is already adequate runs $2,500 to $3,000. When the full service entrance, meter base, and panel all need replacement, the cost rises to $3,500 to $4,500.

An ESA permit is mandatory for this work, and the cost of the permit is typically included in your electrician's quote. Many Ontario insurance companies now require fuse box replacement as a condition of coverage, so this upgrade may actually save you money on premiums or prevent policy cancellation. The entire project usually takes one day of on-site work.
