At the November meeting of the league, the NHA decided:
charging a player into the boards is a major foul,
match foul penalized by 10 minutes off and $15 fine.
Pre-season
Along with Montreal Nationals president A. L. Caron, player Art Ross attempted to organize a new hockey league with teams in Ottawa, Montreal, Toronto and Boston. The arena owners in all of the cities turned down the new league and killed the idea. Ross was suspended by the NHA, but by January 7, Mr. Ross was reinstated. He signed with Ottawa.
A record long overtime game was played in Quebec on January 13 between Quebec and the Canadiens. Quebec defeated Montreal 3–2 after 50 minutes and 28 seconds of overtime, on a goal by Jack McDonald. Coach Jack Laviolette had to take over for Georges Vezina after Vezina was penalized.[2]
The Ontarios had to forfeit their February 3 game with the Wanderers after the McNamara brothers took a personal leave to attend their fathers' funeral. Owner Eddie Livingstone of the Ontarios asked for a postponement but the Wanderers refused.[2]
A game on February 17 between Toronto and Ottawa turned into a brawl before Toronto police arrested Art Ross and Roy McGiffen to calm the proceedings.[2]

Playoffs
League championship
Montreal and Ottawa played a two-game total-goals series to determine the league championship. In the first game, Ottawa's Art Ross scored in the first period to give the Senators the lead which they would not relinquish. In the second, Angus Duford scored to push the lead to 2–0 after two periods, and Horace Merrill and Jack Darragh scored to make it 4–0.[4] In the second game, the Wanderers' Donald Smith scored in the second period, but the Senators held the Wanderers off with tight checking to win the series 4–1 on goals.[5]
For the win, Ottawa was awarded the O'Brien Cup. Since the NHA champion of 1914 was the defending champion of the Stanley Cup, Ottawa now took possession and defence of the Stanley Cup as well.[6] The Senators engraved their series win over the Wanderers on the Stanley Cup and travelled to Vancouver for the world championship series against the Vancouver Millionaires.
Exhibition series
The Wanderers, Canadiens and Bulldogs played an exhibition series in New York and Boston. The Ontarios and Torontos played an exhibitions series in Cleveland, Ohio.[7]
As the 1914 Final was held in Toronto, all three games in this series were played at the arena of the PCHA's champion in Vancouver, British Columbia. The Millionaires swept the best-of-five series in three games.
