Well I' m not from Canada, but as close as you can get and still be in the U.S. Dressing in layers can' t be stressed enough, it is essential for cold weather hunting. I use a layer of polypro as my base layer (moisture-wicking), then duofold underwear, then a layer of fleece and finally my outer layer of wool. No synthetic fabrics can match wool for it' s ability to keep you warm even when wet.

You say your main problem is cold feet. My feet stay cold due to circulation problems. I wear a thin pair of moisture wicking socks under thick wool socks, inside of a well-fitting boot with 600 grams or more of thinsulate. Well-fitting means a nice snug fit (try on the boots with thick socks before buying), but not so tight as to restrict circualtion. When the weather drops well below zero, and if I will be stand hunting, I like to use a pair of insoles that include a compartment to hold the Hothands type footwarmers. I bring a few extras along since I hunt all day.

In the past I had two pairs of boots, one for stand hunting and one for tracking and still-hunting. My warmer pair were Lacrosse Icekings (if I remember right) rated to -100 F. My feet never got cold in those, but they were quite awkward and heavy, making it hard to sneak into the woods quietly.
