Does it get cold and stay cold up there? It must. -40 sounds pretty brisk.
Most of my winter cycling was in south western Ontario. My biggest issues were because it wouldn't stay cold. When it thaws, then gets cold again there's ice everywhere. It also seemed to cause all of the fluffy snow to turn into a crunchy layer of ice, which is much less comfortable to ride through and fall into.
I used to, but it changing now. My first couple of years it would stay below -30 for a few months. Now it gets up to +10C in the middle of Jan randomly.
I put studs into my tires and actually never slipped on ice once (though I sure have on foot...)
