History
Because the Stanley Cup had become a trophy for professional hockey teams, Sir H. Montague Allan in 1908 donated a new trophy to be awarded to Canada's best senior amateur team.
The Allan Cup was formally given to the Victoria Hockey Club (VHC) of Montreal, with the provision that, after being presented to the champion of the VHC”s league, it should become a challenge trophy. The Ottawa Cliffsides won the trophy as league champions in 1908, then lost to Queen's University in the first challenge.
Within a short time, there were so many challenges for the Allan Cup that the trustees appointed by Allan began arranging a series of regional elimination games to determine the challenger.
In December of 1914, the Canadian Hockey Association (CHA) was formed, with affiliated bodies in Quebec, Ontario, Manitoba, Saskatchewan, Alberta, and British Columbia. The trophy then became emblematic of the CHA senior amateur championship. In 1928, the trustees formally gave the Allan Cup to the CHA. Since 1984, the trophy has gone to the winner of Canada's Senior AAA championship.
