THE MANN CUP is awarded annually to the senior "A" men's box lacrosse champions of Canada. The championship is currently a best-of-seven, East vs West series played between the league champions of Major Series Lacrosse in the East, and the Western Lacrosse Association in the West.
The Cup is one of the oldest continually awarded championships in North America, having been donated by Sir Donald Mann, a Canadian railway contractor and entrepreneur, in 1910 to replace the Minto Cup as the senior amateur lacrosse trophy in Canada.
Sir Donald Mann's cup is now in permanent residence at the Canadian Lacrosse Hall of Fame in New Westminster, BC, being made of solid (albeit low-karat) gold, and was appraised by Birks to be valued at CA$60,000 in May 1980, or over CA$222,000 in today's dollars.
Teams have been awarded a replica trophy since 1985, which has a larger and taller base than the original trophy - the replica currently in use is actually the second replica trophy, as the first was destroyed in a bonfire mishap in Peterborough, ON in 2004.
The cup was originally a field lacrosse, challenge cup until 1925, when the then-champion New Westminster Salmonbellies turned the cup over to the Canadian Lacrosse Association (now Lacrosse Canada) and it became part of a national playoff, but still in field lacrosse. The next change would be from field lacrosse to box lacrosse in 1932.
Since the change from a challenge up to a national playoff system in 1926, the Mann Cup championship has only been missed twice - in 2020 and 2021 due to the COVID-19 pandemic.
Alongside the Mann Cup is the Mike Kelley Memorial Trophy awarded to the Most Valuable Player of the competition. Named after Michael Edward Francis "Mike" Kelley, owner and manager of the Hamilton Tigers lacrosse club in the 1930s, and later the President of the Ontario Lacrosse Association and Canadian Lacrosse Association.
