open mike, I've been Canadian all my life and I've never heard the term CanUK.   "Canuck" yes--a common slang reference to Canadians in general and French Canadians in the northeast US in particular.

We have nothing to do with the UK, citizenship wise, and don't need visas to travel in the States. Garg's off his meds again, not a good prescription when you're a dork to begin with.
