 The ORFU withdrew from Grey Cup competition after the 1953 season, and the WIFU champion was given an automatic berth in the Grey Cup final.For this reason, 1954 is reckoned as the start of the modern era of Canadian football, in which the Grey Cup has been exclusively contested by professional teams.Since 1965, Canada's top university football teams, competing in what is now U Sports, have competed for the Vanier Cup.
