The math is simple, the bill is not
Energy cost = (watts / 1000) × hours per day × days × rate. The trap is that real electricity bills add 30–50 % on top of the energy line for fixed delivery charges, regulatory recovery, debt-retirement charges (Ontario), and sales tax. That makes apples-to-apples appliance comparisons hard unless you isolate the energy line, which is what this calculator does.
Where Canadians pay the most (and least)
Quebec is by far the cheapest at ~8¢/kWh — Hydro-Québec residential block 1 (first 40 kWh/day) is the lowest rate in North America. Manitoba and BC follow at 10–11¢. Most provinces sit at 13–19¢ thanks to the Federal Carbon Pricing pass-through and aging grid investments. Alberta deregulated rates float with natural-gas costs and have spiked above 30¢/kWh in tight-supply months. The Territories run 35–37¢/kWh, partly subsidised by federal transfer payments under the Northern Residents Deduction.
Vampire loads add up
The average Canadian home runs 50–100 W of constant baseload from cable boxes, smart speakers, network gear, gaming consoles in standby, and trickle chargers. At 13¢/ kWh that’s $57–$114/year — bigger than most people realise. Smart power strips that cut entertainment-cluster standby pay for themselves in 12–18 months.
Heat pumps change the math
Modern cold-climate air-source heat pumps run at COP (coefficient of performance) ≈ 2.5 even at −15 °C, meaning 1 kWh of electricity delivers 2.5 kWh of heating. That makes them cheaper to run than electric resistance baseboards (COP = 1.0) and competitive with natural gas everywhere except mid-Alberta. The federal Greener Homes Grant subsidises switching, with provincial top-ups available in BC, NB, NS, NL, PE and YT.
