I know someone who won a contest for the 777 Tour and to be on the 777 Plane for the whole week.
But he got an issue with the canadian visa, it was the only issue, so the radio gave the ticket to another person.
Canada is not THAT easy to enter, maybe it is for US residents.
From someone who actually knows what they are talking about, you have to have a permit and a passport and all that jazz. My father has been there numerous times for hunting.
