Known originally as the OHA Memorial Cup, it was donated in 1919 by the Ontario Hockey Association in honour of the soldiers who died fighting for Canada in World War I. From its donation in 1919 until 1971, the Memorial Cup was awarded via a series of playoffs to the junior hockey champion of Canada. The Canadian Amateur Hockey Association moved to the current tournament format in 1972 when it divided Junior A hockey into two tiers, naming the Memorial Cup as the championship of the Major Junior rank. Sixty teams across the CHL's three member leagues are eligible to compete for the Memorial Cup, representing nine provinces and five American states.
