In this season, the Ottawa Hockey Club became more commonly known as the 'Ottawa Senators'.
Taylor, who had been barred from joining the Senators by the Wanderers, became eligible to play for the Senators when the Wanderers dropped their interest in him, but he chose to move out west where he would remain for the rest of his life.
Marty Walsh, who had become a part-time player in the 11–12 season, retired.
Two new players joined the Senators lineup this season, Punch Broadbent and Clint Benedict, who would both play for Ottawa into the 1920s.
[2] Defenceman Horace Merrill, who had previously been a spare for the Senators, joined them full-time this season.
