Really depends on where you are. Parts of Ontario and BC you could probably get away with just a heat pump, but lots of places in the prairies you could only use a heat pump for maybe 1/2 of the winter months. It's just too cold the rest of the time, so you'd have to augment with electric or gas anyways. With the amount of flak raised about infrastructure not being able to handle electric vehicles I can't even imagine the chaos if the prairies went electric heat. I'd really like to see strong baseline energy efficiency standards put in provincially for new builds and a lot of investment in retrofit, but with the current political climate in the prairies that's impossible. Promoting anything that doesn't burn both oil and money is anathema.
