I don't know how you guys in Canada feel, but I have to say I think the heater in the Nox is excellent--quick to heat up and quite powerful. Put on the recirc for a little bit and you're toasty in no time! Wife loves it, especially in comparison to my Mazda 3 (and my Beetles, but that's another story...) Even when the temps are in the mid-teens (°F) we have no problem. Love it!
