Lawsuits aren't really anything new for the three major junior leagues that make up the Canadian Hockey League (CHL). The Quebec Major Junior, Ontario, and Western Hockey Leagues have seen a few class action suits centred around hazing, assault, and harassment. The latest comes with a twist, though as a lawsuit filed in the United States accuses the CHL of running a cartel.
Players in the CHL leagues are not allowed to play in the AHL until they are 20, as per an agreement with the NHL. If you make an NHL roster from those leagues under the age of 20, you can't be demoted to the AHL, and are instead sent back to your respective CHL league. There are stipends and/or benefits in the QMJHL, OHL, and WHL, but it isn't as much as the AHL, which appears to be the main issue behind the lawsuit.
