It's junior ball - a level below college and not in any way "semi-pro." In Canada, it's considered a tune-up for later play in CIS (university) or NCAA ball (a few kids earn spots on Div 2/div 3 schools from junior.) It is the latter that's important, because if any of the players were re-imbursed, not a single one would qualify for scholarship opportunities, due to the NCAA rules on such things.
