In 1891, the teams that formerly made up the main circuit for the Montreal Winter Carnival played a season-long stand-alone hockey league that was a successor to the popular winter festival. In fact, the MWC Hockey Tournament was cancelled as the teams decided to focus on their own league play. The Montreal Hockey Club, Montreal Crescents, Montreal Shamrocks, Montreal Victorias, Quebec Hockey Club, and the Ottawa Hockey Club participated in a challenge schedule at the Crystal hockey rink, following the same format found in the predecessor Montreal Winter Carnival.
The fifth season played in 1891 (from January 2 to March 5) saw The Montreal Hockey Club win the Championship.

The AHAC was the first ever organized Ice Hockey league. It was formed by four Montreal-based teams plus a team from Ottawa. Because these five teams all played in the preceding MWC Hockey Tournament, the AHAC is considered to be the direct descendant to the MWC for historical and statistical purposes.
