The Canadian Amateur Hockey Association divided Junior A Hockey into two categories, Tier 1 and Tier 2.Tier 1 was limited to only three leagues, the Ontario Major Junior Hockey League, the Quebec Major Junior Hockey League, and the Western Canada Hockey League. The remaining Junior A Leagues fell into Tier 2. Only Tier 1 Leagues were allowed to play for the Memorial Cup, Canada’s Junior A Championship. In time, Tier 1 would become known as Major Junior, and Tier 2 as simply Junior A.
