2012 Manitoba Saskatchewan Senior Playoff

Due to the 2012 Allan Cup being held in Lloydminster, Saskatchewan the 2012 Rathgaber Cup was not needed due to the fact that no team from Quebec was participating in Allan Cup qualifying. Traditionally, the host branch would receive the unused bid and the regional bid would go to the team that would have been the final opponent in qualifying.
