For what it's worth, here's my $.02 worth.
I don't think that Canadian winter in a Boler
in Halifax is do-able. The trailer is NOT insulated and your severe low temperatures, and heavy snowfall, "Down East," would make your heat bills astronomical. Not to mention the frozen water tank. If you have a toilet model, it will surely freeze up and then where would you go???[pun intended]. Over an extended period, moisture would become a major problem. Even with a heater you would get frost on the walls and inside the compartments. You're feet will always be in the cold zone.
Think very carefully about what you are suggesting. A Boler
is like a hard shelled three seasoned tent and doesn't work well in sub-zero temperatures.
Splitting the cost of an apartment or living in a dorm is better than freezing and not being able to concentrate on your courses..
This is just a Dad's opinion so you're welcome to ignore me, BUT think very, very carefully about it.
Good luck with your year whatever you do.
