The Montreal Junior League operated in 1931-32 and 1932-33 in and around Montreal. Their champions entered the Quebec Junior Playoffs.
In 1931 the Mount Royal Junior League was forced out of the Mount Royal Arena because of a lack of ice time. The games were played at the open-air rink at Loyola College. The name was then changed to the Montreal Junior League.
In 1933 the league moved back to the Mount Royal Arena and assumed its original name.
