The tournament included the five senior league champions. Because host Moncton was also a champion, a wild-card spot was available. As the previous wild-card had gone the GPAC, it continued its eastern procession and was given to the OUAA. The six teams were sorted by a committee prior to the tournament and arranged so that the two GPAC teams would be in opposite groups.In the round-robin groups, the teams that finished with the best record would advance to the championship game. If there was a tie for the best record, the first tie-breaker was goal differential. If there was a tie in goal differential, the teams would play sudden death overtime for the advantage.
