1970–71

OHA president Tubby Schmalz was concerned with the level of physical play during the season, and personally interviewed four players to dissuade them from further on-ice misconduct. He submitted recommendations to the 1971 Canadian Amateur Hockey Association general meeting on behalf of the OHA to reduce the curvature of the hockey stick to one half inch for player safety. He also suggest to revert to the rectangular Ice_hockey_rink#Crease, goal crease from the recent change to a semi-circle, since some rinks in his league were used by professional teams who used the old rules for the goal crease. Schmalz wanted to see consistency the application of the rules, and raise the standards for the level of instruction given to players. He instituted Official (ice hockey), referee and Coach (ice hockey), coach clinics in the OHA, prior to it being mandated at the national level. In 1971, he sought to hire a technical director to conduct coaching and refereeing clinics across the province.

Schmalz announced that teams from the OHA and the Quebec Major Junior Hockey League would not play against any team from the Western Hockey League, Western Canada Hockey League (WCHL) for the 1971 Memorial Cup, due to disagreements over travel allowances given to team at the Memorial Cup and the higher number of over-age players allowed on WCHL rosters. He said that plans for an Eastern Canada series for the George Richardson Memorial Trophy would go ahead. As of the OHA playoffs, he reiterated that teams were still unanimous in their decision not to play for the Memorial Cup against WCHL teams. The Peterborough Petes finished first overall in the regular season, winning the Hamilton Spectator Trophy. The St. Catharines Black Hawks won the J. Ross Robertson Cup.
