I would say there's no harm in trying, but there's a risk of violating something that may or may not be in the Terms of the booster about service address. When you get a Booster, you agree it will be in a specific Service Address as it's used in the event of 911. Hypothetically, you're not supposed to use it anywhere besides where it's intended.
Personally, if you're not going to use 911, I don't see the big deal.
But, seriously, I don't see harm in trying it once to see if it works and if it does, determine if the agreement allows you to use it in two locations or buy a booster somewhere to keep in the cabin.
My bet would be not. They are designed to work only where T-Mobile has a license to operate and that's not Canada.
