Teams were restricted to a maximum of five imports, and only players who had lived in Canada for a full year could compete in the Grey Cup game.[1] When Regina won the West, five of their imports were declared illegal by the Canadian Rugby Union (CRU). Regina offered to drop the players for the Grey Cup, but the CRU would not allow them to play for the cup. Instead, the Grey Cup was a contest between the Sarnia Imperials of the Ontario Rugby Football Union (ORFU) and the Ottawa Rough Riders of the Interprovincial Rugby Football Union (IRFU). Sarnia won their second and last Grey Cup with a powerful line-up that included future Hall of Famers Hugh (Bummer) Stirling and Ormond Beach.[2]
The IRFU and WIFU adopted a two-game point series format for the playoffs. The series was played between first and second place teams.[1]
A white ball was used in games played under floodlights in Western Canada.[1]
Intercollegiate teams stopped competing for the Grey Cup.[1]
The Regina Roughriders fielded two teams; the main, or "big" team in the WIFU, and the "little" Roughriders who played in the last SRFU season.
The Calgary Bronks played a full schedule in the Alberta Rugby Football Union including some games which conflicted with the WIFU schedule. For the open dates, the Bronks fielded the same team that was competing in the WIFU (5 games). For the remaining three games, the Bronks fielded a second team which was referred to as the Calgary Bronks 'B'.
The final game of the regular season saw the Calgary Bronks square off against the University of Alberta Golden Bears. These teams were the two top teams in the ARFU, so it was decided that in addition to being the final regular season game, the game would also determine the ARFU championship.
^Regina spotted five points to start the game as when WIFU organized, "it was agreed by all teams that the points separating the teams in the league standings would be carried into the western playdowns." Regina had a five point differential in points over Calgary in the WIFU standings.
