Electric stoves in Canada use either a 3-wire or 4-wire connection. Newer installations require a 4-wire cord (hot, hot, neutral, ground) under the Canadian Electrical Code, while older homes may have a 3-wire outlet (hot, hot, neutral — with neutral doubling as ground). When replacing a stove cord, match the cord type to the outlet at the wall. Do not replace a 4-wire outlet with a 3-wire cord — this removes the dedicated equipment ground and is not code-compliant for new installations.
If the wall outlet is a 3-wire NEMA 10-30 or 10-50 and you want to upgrade to 4-wire, a Licensed Electrical Contractor must run a new cable with a dedicated ground from the panel to the range location. This requires an ESA permit. EZSMART handles range circuit upgrades and appliance outlet installations across Ontario.
