In 1962, the Canadian Intercollegiate Athletic Union announced that it would be holding the first national collegiate tournament in 1963. In response, the Western Canadian Intercollegiate Athletic Union (WCIAU), reformed as the Western Canadian Intercollegiate Athletic Association (WCIAA) and its champion would automatically receive a berth into the University Cup tournament. The move prompted Manitoba to return to the conference, bringing the number of members back up to four. In 1964, British Columbia was forced to withdraw due to high travel expenses, however, the addition of Calgary allowed the league to remain a foursome. Two years later, UBC returned and the league held its first postseason tournament thanks to a tie for first in the standings. Two more additions in 1969 brought the league up to eight members and the conference adopted a playoff tournament as a permanent fixture.
† Alberta and Brandon were both forced to forfeit 4 games for using ineligible players during the season. In the match between the two teams, both squads were awarded a loss.
