I hunt from a ground blind in Wisconsin where it gets as cold as both places you describe. Here is what I recommend you look into. Getting clothing that you can layer will allow you to be prepared for anything.
Base wicking layer: A lightweight polyester long john such as the lightweight Wickers Comfortrel longs from Sierra Trading Post or lightweight Duofold Varitherm polypros from Campmor. Do not get them so they fit too tight or too loose, they should contact your skin without feeling too tight or binding anywhere.
Warmth layer: Lightweight or Midweight Merino wool long johns such as Terramar Thermawool or Woolskins, Windsor Wear and Stanfields Superwash Wool. You can go with Smartwool, Filson, Icebreaker or Ibex but it will cost you. Ullfrotte' Original 200 gm/m³ wool longs are available for $30 a piece from Montana Woolen Shop. Again, not too tight when worn over the base layer. If the temperature outside is on the warm side you can use just the lightweight base layer described above, if a little colder just these, if colder yet use the base layer under the warmth layer.
Shirt: Woolrich Alaskan wool or Cabelas Worsterlon II.
Pants: Woolrich Malone, Johnson Adirondack Plaid or Bemidji Lumber Jac wool pants. Get heavy-duty button suspenders. Consider a lightweight waterproof shell pants to wear over them if it rains or there will be wet snow, however I've never needed such wearing heavy wool pants.
One ragg wool sweater for layering over the above; it must not be too tight or bind when worn over the garments under it. $35 from Cabelas or a Ragg Henley from L.L. Bean for $45.
Feathers: A lightweight down vest or jacket for layering over the above. It must fit comfortably over all that is worn under it. Cabelas Lightweight Down Jacket is the best and probably the cheapest. You can mix and match the shirt, ragg sweater and feathers to adjust for conditions.
Outer coat: Anything Goretex with a detachable hood that will fit over everything under it. No more than 200 gram Thinsulate if any insulation.
Hat: Stormy Kromer
Neck Gaiter: Smartwool or fleece.
Socks: Wicking polyester or polypropolene liners under the Wigwam IceSock, Cabelas Wool Boot Sock or Fox River Outdoorsox.
Mittens/Gloves: Cabela's Canadian Stand Hunter Gloves
Boots: Cabela's Polar Cap Pac Boots or something similar; they must not be too tight fitting with your selected socks. When blood circulation to the feet becomes restricted they will become cold no matter how much boot insulation is used. You can consider a regular insulated hunting boot and employ boot blankets when you get to your stand.
Hand, body and foot warmers: The mitts above have a pocket for hand warmers. Body warmers should be placed over your kidneys. Put in a foot warmer insole or toe warmers.
Backpack: Somewhere to stow layers when you are not wearing them, good for your other gear as well.
