I would not suggest steel in any part of Canada. There are more than a handful of quality fiberglass doors that can run similar profile sizes based out of Canada.

If you are totally set on Steel, there Bliss Nor-Am makes some nice stuff.

As WoW alluded to, steel doesn't make out so swell in cold climates as it is steel and the thermal properties are not good, even thermally broken. Also hang on to your hat when you get the pricing as they are 2 to 2.5 times the cost of aluminum.

Thanks so much for the feedback! Very useful!

inline make a nice fiberglass window and they are in canada.

Marvin Modern is supposed to be designed around these contemporary sitelines, but I don't know if they do swing doors. I think they do.
