In order to cut down on travel expenses, the WCIAU had split into two conferences in the offseason; the GPAA and Canada West. However, while the champion of both would be invited into the tournament, an arrangement was made where both would play one another in a quarterfinal round that would serve as a de facto championship for Western Canada. The remaining teams were sorted by committee. The Quarterfinal and Semifinal rounds were best of three series and the third place game was discontinued.
