The tournament reverted to a bracket format. Since the OUAA served as tournament host and possessed two entrants, both teams received byes into the semifinal round. The first round was arranged as a regional final with the two western teams and two eastern teams each battling for a spot in the national semifinals.
The regional rounds were played as best of three series while the national semifinals were set as two-game total-goal series. The championship game remained a single elimination match.
The East regionals were held in Winnipeg, Manitoba. The West regionals were held in Gatineau, Quebec.
