Buying the heater separately?
Ask your installer whether they supply the part. If you need to buy it, start with your exact vehicle and engine. A factory-installed heater may only need a matching replacement cord.
Only missing the cord?Honest answer: most Toronto drivers don't need a block heater. January mean lows around -7°C are inside the comfortable range for modern engines and synthetic oil.
The exceptions: diesels, vehicles parked outside during polar-vortex weeks, commuters to cottage country, and older vehicles with tired batteries. For those cases a block heater or battery blanket is cheap insurance — and if you're moving to the Prairies, get one installed before you go.
