Spotting a Canadian in the wild is a lot like determining if a thing is sports or not, in that there is a two-step approach. It is, however, much simpler to spot a Canadian. The first thing you must do is determine whether the person is holding a hockey stick, wearing ice skates, and attempting to skate on a toilet bowl that has overflown and frozen over. If everything checks out there, and it does here, then we move on to step two: does the person admit they are Canadian?
