Teams play a 14-game regular season schedule before league playoffs conclude with the ALL Cup.

Founded by Paul St. John in the summer of 2016, the ALL began with six teams for their first season in the winter of 2017.

Oshawa Outlaws, Paris RiverWolves, Peterborough Timbermen, Six Nations Snipers, St. Catharines Shockwave and Toronto Monarchs were the original six of the ALL.

Expansion in the west happened prior to the 2022 season when a four-team division was announced.

ALL added a women's division in 2018 with three teams (RiverWolves, Shockwave and Snipers) competing in the first season.
