Although I've never been to Canada, this is some serious advice that has a healthy dash of humor:
Bears. Don't fuck with em.
Its cold. Get used to heavy clothing.
Depending on how close you are to big city/rural areas, you get to experience big 4wd trucks!
And I do believe you can own rifles and shotguns. Have fun!
