Yellowknife is the coldest city in Canada — January mean lows near -30°C and stretches below -40°C every winter. Unplugged vehicles simply do not start. Every parking lot has power, every vehicle has a cord, and many run a block heater, oil pan heater, and battery blanket together on a three-way splitter.
Above the 60th parallel, engine pre-heating is a safety system. Locals also fit winter fronts over the grille and leave vehicles idling in deep cold — practices that raise eyebrows down south and save engines up here.
