No, Massachusetts, so probably warmer than you, depending on where you are.

Even in Canada, though, I'd look into whether heat pumps with resistive auxillary heat are economical. If it only ever goes below -20⁰F for, say, a week a year, you'd probably still come out on top. And you'd definitely come out on top environmentally if your electricity is mostly green.

And with heat strips, a heat pump unit can continue to provide heating even below -20. Heat strips do make the heat pump more expensive, but I would wager they're less expensive than having a separate furnace.
