Heating in Canada will use ~kW, in the summer I'm not using any device in that order of magnitude, including humans (which are what, 100W?). If I remember correctly, the energy use of heating/cooling is related to the square of the temperature difference, so if ACs with a low temperature delta use nearly as much energy as heating does in winter, with its higher delta, it indicates that there may be a lot of waste.
