Should I upgrade my panel before a kitchen renovation?

In most cases, yes — a kitchen renovation is one of the best times to assess and likely upgrade your electrical panel, especially if your GTA home has 100 amp service or an older panel with limited space. Modern kitchens are the most electrically demanding rooms in a home, and a renovation is your opportunity to bring everything up to current Ontario Electrical Safety Code requirements.

A modern kitchen requires a surprising number of dedicated circuits. The Ontario Electrical Safety Code mandates at least two 20 amp small appliance circuits for countertop outlets, plus dedicated circuits for the refrigerator, dishwasher, microwave, range hood, and garburator. If you have an electric range, that requires a dedicated 40 or 50 amp circuit with heavy-gauge 8/3 or 6/3 NMD90 wire. A wall oven and separate cooktop each need their own dedicated circuits. Under-cabinet lighting, a kitchen island with outlets, and a built-in coffee station or wine fridge all add circuits. By the time you tally everything, a properly wired modern kitchen can require ten to fifteen circuits — and that is before you account for the rest of the house.

In post-war homes across Scarborough, North York, Etobicoke, and the inner suburbs, the existing panel often has 100 amp service with a mix of 15 and 20 amp circuits. Many of these panels were installed with 20 to 24 circuit spaces, and after decades of additions — a central AC circuit here, a basement circuit there — they are physically full. You cannot add the ten new kitchen circuits you need because there is nowhere to put them. Even if you use tandem breakers where the panel allows them, you may still run out of space or exceed the panel's rated capacity.

The cost calculation usually makes a combined approach the smartest move. A panel upgrade to 200 amps runs $2,000 to $5,000, and the kitchen electrical rough-in will cost $3,000 to $8,000 depending on the number of circuits, the complexity of the wiring runs, and whether walls are open or closed. Doing both at the same time saves money because the electrician is already on site, the walls are already open, and you only need one ESA permit and inspection for the combined scope. Trying to squeeze new kitchen circuits into an already-full panel often leads to problems during inspection, and you may end up paying for a panel upgrade anyway.

Your electrician will perform a load calculation to determine definitively whether an upgrade is needed. If you are planning a kitchen renovation, Toronto Electrical Repair can match you with a licensed electrician who can evaluate your panel capacity and plan the electrical scope alongside your contractor.
