The Sir Winston Churchill Bowl was a trophy which was originally donated and managed by McGill University to serve as an annual, often pre-season, invitational football contest between the sister universities of McGill and UBC in aid of the Canadian Paraplegic Association.
The trophy is a sculpture created by R. Tait MacKenzie entitled "The Onslaught".
The Churchill Bowl was retired in 2003 and replaced by the Uteck Bowl.
The Churchill Bowl was originally created for Canadian University football invitational competition in 1953.
Many of the games were regarded as an unofficial national championship of Canada. From 1953 through 1958 the game was a pre-season interconference exhibition. In 1959 and 1960, the Churchill Bowl was switched to a post-season game, pitting the Yates Cup and Hardy Trophy champions against each other in the first attempt in an unofficial national championship. There were eleven unofficial national championship or challenge games played between 1953 and 1964.
Staging games could prove to be difficult at times. In 1961 the Queen's Golden Gaels were the Yates Cup champions scheduled to play the Western Canadian Hardy Cup champion Alberta Golden Bears. However, the Ontario Intercollegiate Football Conference champion McMaster Marauders challenged Queen's to a post-season match which the Gaels were forced to play. With no game scheduled, the McGill Redmen hosted the Jewett Trophy champion St. Francis Xavier X-Men.
In 1963, the Hardy and Yates champions again faced off in the "Golden Bowl" between the Alberta Golden Bears and Queen's Golden Gaels, but McGill chose hold onto to Churchill Bowl and play the Atlantic champion St. FX for a third consecutive year. Alberta's 25-7 victory marked the first major western victory over an eastern team, with McGill also losing to the X-Men in the Churchill. These events spurred an effort to create an official national championship.
When the Vanier Cup was staged as an official national championship in 1965, the trophy was retired. In 1989, the bowl was recommissioned and taken out of storage at McGill was one of the two national semifinal men's football games of Canadian Interuniversity Sport. The winner of the Atlantic Bowl would meet the winner of the Churchill Bowl for the Vanier Cup.
