Former QMJHL players hold many of the Canadian Hockey League's career and single season offensive records.

Hockey Hall of Fame alumni of the QMJHL include Mario Lemieux, Guy Lafleur, Ray Bourque, Pat LaFontaine, Mike Bossy, Denis Savard, Michel Goulet, Luc Robitaille, and goaltenders Patrick Roy and Martin Brodeur.

The eight teams from the QJHL were the Drummondville Rangers, Quebec Remparts, Saint-Jérôme Alouettes, Shawinigan Bruins, Sherbrooke Castors, Sorel Éperviers, Trois-Rivières Ducs and the Verdun Maple Leafs.

It threatened a lawsuit to force the Montreal Junior Canadiens of the Ontario Hockey Association into the Quebec-based league.

In December 2023, the QMJHL changed its name to the Quebec Maritimes Junior Hockey League and released a new logo.

The change recognized the league's expansion into the Maritime provinces, whose teams had been a part of the QMJHL for almost 30 years.

The Newfoundland and Labrador House of Assembly amended labour laws in 2024, to consider junior players as student-athletes and not employees subject to minimum wage, similarly to other provinces in the league.
