I found an old-time square dance competition here: The Vankleek Hill Fiddling Step Dancing and Square Dancing Competition. Here are the rules (PDF document). It’s kind of interesting; the squares dance to the house caller, and need to be able to do one of several traditional squares as well as respond to several different break calls. They also dance to their own caller.

Canada seems big on square dance competitions; I previously wrote about a competition at the University of Guelph. And many of the Northwest Teen Competitions take place in the Vancouver area; according to this page, the competition started in Vancouver.
