Electricity cost in Quebec is around USD $0.05/kWh. Combine that with the fact that most alternative heating sources are at a premium (natural gas, propane and oil all cost substantially more in Quebec than they do in, for example, Texas) and the fact that 98% of Electricity is renewable source, that leads to a very heavy proportion of electric heat. It's not uncommon to have residential units exclusively heated by baseboard heaters - the least efficient means as far as energy required per unit of heat - however it's still cheaper to operate on a yearly basis than a natural gas furnace, while costing 20% of that to install/maintain.
