There isn't much currently, to be honest. I absolutely adore the Guelph contemporary dance festival. I lived in Guelph for a couple of years so I'm really glad you brought it up.
A contemporary dance artist, choreographer or company would go into a contract with the festival, for example, to present the work. If the work becomes a success—and in Canadian dance that means we get to see maybe five shows in two different cities, we're really talking about small scale here—that means that everything is decided on a contract basis with that presenter. If another presenter wants to purchase it and, let's say, it's going to be performed by different dancers in maybe a slightly different context, there is a very small chance that a royalty could be paid, but really we're only seeing royalties being paid 99% of the time in ballet.
That example in contemporary dance doesn't happen very much.
