The Metropolitan league was founded in 1954-55 as an outgrowth of the Mount Royal Junior League. It was a Junior B league with restrictions on the number of 18-20 year old players that could play,
After the Quebec Junior Hockey League folded in 1955 the Metropolitan league created a junior A and Junior B division. The Metropolitan Junior A league became, by default, one of the leading junior leagues in Quebec.
It was mainly a feeder league for Ontario Hockey Association junior teams, mostly for the Montreal Junior Canadiens. Many of the Junior Canadiens' stars played in this league, including Yvan Cournoyer, Serge Savard. Jacques Lemaire, and Carol Vadnais.
Sometimes the league champions would play for the Memorial Cup with good success against teams from Ottawa and the Maritimes but no chance against the Ontario teams.
This league existed until 1968-69. In 1969 the Jr.A league merged with the Provincial Junior League to form the Quebec Major Junior Hockey League which would be capable of competing with other junior teams from Ontario and the west.
The Metropolitan Jr.B league continued, and merged with the Montreal Jr.B league in 1971, and operated until 1981, when its remaining teams joined other Jr.B leagues or the CEGEP AAA divisions.
