The league is the result of the 2002 amalgamation of several men's senior elite level baseball teams in the province of Quebec.

There were originally ten teams, five from the Montreal area, four from Quebec City and one from Trois-Rivières.

Other competitive levels of play in Quebec have since followed suit (senior, junior and midget).

In 2008, the league participated in and won the Vintage Base Ball World Series in Massachusetts.
