Not in Canada, but near Louisville, KY, we stayed at a KOA there one week-end and I talked to the owner of the campground. I was questioning why so many campers had the big 100 or 150 pound propane tanks, and some folks even had 2 of them. She said they were seasonal campers (but they are open all year round), and then she mentioned 3 different construction projects going on in Louisville for several months, and these were several of the construction workers on those jobs. She said they were great people, most lived by themselves, good tenants, and they were good people. They go to work all day, come back at night, crash, get up the next morning and go back to work. The campground was incredibly quiet and very clean and neat! Just very tight and narrow campsites. (but not a bad place to park at all).
So, if you have construction abilities, I'm sure there are construction companies (even in Canada), that require their people to move from place to place every few months. This would be my first area I'd check into if it wre me.
