What are the current Ontario Electrical Safety Code requirements for kitchen outlets?

The Ontario Electrical Safety Code requires that all kitchen countertop outlets be GFCI-protected, on dedicated 20-amp circuits, and spaced so that no point along the countertop is more than 900 millimetres from an outlet. These requirements are among the most specific and frequently cited sections of the OESC, and they come up constantly in GTA kitchen renovations.

The GFCI requirement exists because kitchens combine water and electricity — a dangerous combination. Every receptacle within 1.5 metres of a sink must have ground fault circuit interrupter protection. In practice, most electricians in the GTA install GFCI protection on all kitchen countertop circuits, not just those near the sink, because it is safer and avoids any ambiguity during the ESA inspection. GFCI breakers cost $35 to $55 each, or you can use GFCI receptacles ($15 to $25 each) at the first outlet in the circuit to protect all downstream outlets on that run.

The dedicated circuit requirement means your kitchen countertop outlets cannot share circuits with lighting, the dishwasher, the refrigerator, or outlets in other rooms. The OESC requires a minimum of two dedicated 20-amp small appliance circuits serving the kitchen countertop area. These circuits handle the heavy-draw appliances that homeowners use daily — toasters, kettles, coffee makers, stand mixers, air fryers — and having two separate circuits prevents constant breaker trips when multiple appliances run simultaneously. In many older Toronto homes, particularly the post-war bungalows across Scarborough and North York, the kitchen may have only one 15-amp circuit serving all countertop outlets, which is why breakers trip every time you run the toaster and coffee maker at the same time.

Beyond the countertop circuits, kitchens also require dedicated circuits for major appliances: the refrigerator gets its own 15-amp circuit, the dishwasher gets a dedicated 15 or 20-amp circuit, and if you have a built-in microwave, range hood, or garbage disposal, each may need its own circuit depending on the amperage draw. An electric range requires a dedicated 40 or 50-amp circuit with appropriate wire gauge — typically 8/3 NMD90 for 40A or 6/3 for 50A.

The spacing requirement ensures that homeowners are not stretching cords across countertops to reach outlets — a safety hazard that also violates code. The rule is that no point along the countertop wall should be more than 900mm from a receptacle. For island countertops, at least one outlet is required if the island has a long dimension of 600mm or more and a short dimension of 300mm or more.

All new or replaced kitchen outlets must also be tamper-resistant — those are the outlets with the built-in shutters that prevent children from inserting objects. This is a code requirement throughout the home, not just kitchens.

During a kitchen renovation in the GTA, the electrical component typically runs $2,000 to $5,000 depending on how many circuits need to be added or upgraded. The ESA permit for kitchen electrical work ranges from $150 to $300 based on the number of devices. If your kitchen renovation involves bringing the electrical up to current code, find a licensed electrician through Toronto Electrical Repair who can handle the ESA permit and inspection process from start to finish.
