In a word: Yes.
I already live in the Great White North, so I think on this on a regular basis.
More fire wood is one thing. Better insulation, more efficient furnace/wood stove would go further I think.
Looking at plants/veggies/herbs that are more cold hardy. And coverings too.
Livestock that is more cold adapt too.
And cold weather gear. We already have most of that, but replacement for old or worn out gear.
