The CRU experimented with a two-game, total points series to determine the champion in 1940. The Ottawa Rough Riders won both games against Toronto's Balmy Beach, 8–2 and 12–5. The Grey Cup returned to its one-game format the following year. Both the IRFU and WIFU suspended operations in 1942 due to the Second World War. Grey Cup play was expected to be suspended along with the unions; however, the military felt the game and sport would serve as a morale booster and organized teams at bases across the country. For the following three years, Grey Cup competition was limited to military teams, and in the 1942 Grey Cup, the Toronto RCAF Hurricanes defeated the Winnipeg RCAF Bombers 8–5 to become the first non-civilian team to win the national championship. Two years later, the St. Hyacinthe–Donnacona Navy defeated the Hamilton Flying Wildcats, 7–6; no Grey Cup championship since then has featured two eastern teams. The conclusion of the war led to the reformation of civilian teams; the IRFU resumed play in 1945, and the WIFU the following year. A push by the sport's organizers to adopt an increasingly professional attitude dominated the post-war period: poor field conditions, previously accepted as part of the game, resulted in numerous complaints against the CRU following the 1949 and 1950 Grey Cups. Field conditions at Toronto's Varsity Stadium were so poor in 1950 that the game has since gained infamy as the "Mud Bowl". Deep ruts in the field and poor weather in the days leading up to the game resulted in a sloppy field covered in large puddles of water. The game also gained notoriety for the near drowning of Winnipeg's Buddy Tinsley, who was found face down in a large puddle, apparently unconscious. Tinsley later said that he had not lost consciousness, but his leg had gone numb from a hard hit to a preexisting injury. Toronto won the game 13–0, the last time a team has been shut out in a Grey Cup game. The ORFU, the last purely amateur union competing for the Grey Cup, withdrew from Cup competition in 1954. Although the IRFU and WIFU champions had faced each other in the Grey Cup final since 1945, the ORFU's withdrawal left the IRFU and WIFU unchallenged as Canada's top football unions. The Eskimos faced the Montreal Alouettes in three consecutive Grey Cups in the mid-1950s, winning all three.
