Memorial Cup remains deeply rooted in Manitoba Junior Hockey League (MJHL) history. For fifty-three seasons, 1919-1971, Manitoba Junior Hockey League clubs competed for the opportunity to earn the National title as Memorial Cup champions. The MJHL which began in 1917-18 as the Winnipeg & District Junior Hockey League until 1933, showed great success throughout five decades with a total of 18 appearances and 11 titles earned by member clubs.
In several of the early years the champion of the MJHL (Winnipeg & District Junior Hockey League) would be required by MAHA (Hockey Manitoba) to play a rural challenger for the opportunity to advance to the Western Canada Memorial Cup Playoffs which generally had the champions of Alberta, British Columbia, Manitoba, Saskatchewan, and Thunder Bay. The winner of the Western Canada Memorial Cup Playoffs would advanced to the Memorial Cup Finals in a series against the Eastern Canada champion.
The Manitoba Centennial Trophy was presented to the CAHA (Hockey Canada) by the MAHA (Hockey Manitoba) in 1970-71. At that time, the CAHA reconfigured their junior tiers, creating two separate classifications – Major junior and Junior A. It was determined that the Memorial Cup, which had served as the CAHA’s national championship since 1919, would become the new championship trophy for the CMJHL (CHL) while the Manitoba Centennial Trophy served as the trophy for the champions of the new Junior A division (CJHL).
