I have to agree with Jon..while there were apparently some US servicemen at the camp they were not involved and did not participate. Several Canadians however were critical to the tunnel, not the least of which was Wally Floody.

Now, I liked the McQueen flic..but really kinda like another US movie about the US capture of Enigma which was a fallacy from start to finish, so much so that it ended up angering Britain so much it was brought up in Parliament.
sad thing is, so little Canadian history is taught in Canadian schools, (only 4 provinces require history classes) that most Canadians know virtually nothing about their history, and what they do know of - history- sadly comes of US movies like the great escape, that enigma movie, Pvt Ryan etc... sigh..
