I've never lived anywhere quite so cold, so I should probably defer to others on the wintertime care issue.

For now, though, the trees will be completely fine outside.
Once it starts to get down below freezing, you probably need to figure out something to do - but even then, the best thing is most likely to mulch them and leave them outside, rather than to bring them in. It's just too dry inside, and trees are unlikely to survive there for long, any time of year.
