The Lethbridge Maple Leafs were, at times, a senior, intermediate, and junior team in Lethbridge, Alberta. After winning the Alberta and Western Canada Intermediate championships in 1936-37, the Maple Leafs sought entry into the Alberta Senior League. Turned down, they played in the West Kootenay League for one season before being admitted into the Alberta League. They proceeded to win that league title three out of four seasons. The Leafs disbanded during World War II.
