They're only two to three times more efficient if they aren't frozen solid. Don't know how it works in Canada, but my mini-split heat pump can't handle a week of 10F let alone -20 C - sure it will put out some heat, but it absolutely needs to be supplemented with my wood stove. And I live in the South. Maybe there's some new high tech heat pumps that cost a fortune and don't freeze over in the insane temps of the great white north? EDIT: hey, folks, how about actually responding instead of downvoting me? If I don't have a clue, please enlighten me. Fuckers.

There absolutely have been new heat pumps hitting the market in the past year or two that are blowing away the previous generation.
