The playoff format of the previous year where the PCHA champion met the WCHL champion prior to playing the NHL champion was abandoned. Therefore, for this year, the PCHA champions were given the chance to play the NHL champion in a best-of-three series. The Senators then defeated Vancouver 3 games to 1 in the semi-finals.

In the first game, Edmonton was leading 1–0, on a goal by Crutchy Morrison, before Lionel Hitchman scored in the third period to tie the game. Duke Keats of Edmonton was awarded a penalty shot during the game, but failed to score. Cy Denneny scored after two minutes of overtime to win the game for the Senators.

In the second game, the Senators got a first period goal from Harry Broadbent and made it stand to the end of the game, playing six-man defense. The shots were recorded; 21, 14 and 13 for a total of 48 by the Senators, and 25, 18, and 25 for a total of 68 by Edmonton. Several players could not play the whole game, including Eddie Gerard and Georges Boucher. Lionel Hitchman played the game with his broken nose in a plaster. Harry Helman played despite a cut to his face from Frank Nighbor's skates, incurred in practice. Cy Denneny had been cut in the leg by the skate of Vancouver's Smokey Harris. 'Super-sub' King Clancy took a turn in all positions, including goal for Clint Benedict in the third period for two minutes when Benedict was serving a penalty. At the time goalies had to serve their own penalties. This is only time that a player played all six positions in a Stanley Cup Final game.

This year was the first time in NHL history that brothers faced each other in the Stanley Cup final. But not just one set of brothers--two! Cy and Corb Denneny as well as George and Frank Boucher faced off in game one.
