I don't live in the north, but I do live in the midwest. We can get below zero temperatures for days or weeks.
In my humble opinion, Papercrete is an ideal material for cold regions. The problems come with the construction process. As spaceman mentioned, working with wet papercrete in the cold can be unpleasant, and difficult. You will want to optimize your construction schedule such that you can work quickly and efficiently during warm weather and get your structure weather tight on the exterior in time for cold weather.
I also wonder about drying times. Papercrete can take a while to dry in colder weather. I have often thought that someone might create a large solar drying "kiln" similar to a wood drying kiln, but built out of plastic. That might extend you building season somewhat, but as the days shorten, so does the amount of solar drying. I'm not positive that the idea would be worth the time and effort, but it's an idea you might want to consider.
Once your structure is completed, papercrete has amazing potential in the frozen north. Just think carefully about your construction process and schedule.
