Ottawa and Montreal met in a two-games, total-goals playoff series for the NHL championship. Ottawa won the first game, 2-0, and Montreal led the second game by the same score until Cy Denneny got a late goal. Despite the 2-1 loss, Ottawa won the series, 3 goals to 2.
In the West, the Pacific Coast Hockey Association began playing six-man instead of seven-man hockey. The PCHA and West Coast Hockey League played an interlocking schedule, but each league kept its own standings.
Both first-place teams, the Vancouver Maroons in the PCHA and the Edmonton Eskimos in the WCHL, won their championship playoffs, setting up a triangular Stanley Cup series.
Ottawa beat Vancouver, 3 games to 1, in a best-of-five series and then swept Edmonton in a best-of-three series. It was the Senators' third Stanley Cup in four years.
