that's odd because Ontario and Quebec are colder than most of the US and just these two provinces account for about one million heat pump installs per year since 2020.

Heat pumps can work great in the northern us. However the experience of europe mostly doesn't apply. You need backup heat of some sort to use a heat pump.

No, you don’t.

Cold climate heat pumps work just fine at even -30 C. In fact, many malls and offices in Northern Ontario are switching to heat pumps only because electricity is so cheap. What heat pumps really need in cold climates is reasonable insulation.
