Canadian Hockey Association (1909–10)

The CHA held the Stanley Cup for its entire eight week existence, as the reigning champion Ottawa Hockey Club was a founding member.

At the regular annual meeting of the Eastern Canada Hockey Association, held at the Windsor Hotel in Montreal on November 25, 1909, three teams from the ECHA (Ottawa, Quebec, and the Montreal Shamrocks) resigned and formed the new Canadian Hockey Association.

The other clubs, most specifically Ottawa, then the Stanley Cup champions, wanted to only play at the Montreal Arena.

The CHA then opened their association to applications from other hockey clubs, rejecting applications from Wanderers which did not commit to the Arena, while accepting two other teams: the All-Montreal, organized by former Wanderers captain Art Ross, and the francophone Montreal Le National.

During the CHA season, Ottawa as Cup champion played one challenge in addition to their regular schedule: Ottawa played a two-game total goals series against Galt HC, champions of the Ontario Professional Hockey League and prevailed with 12–3 and 3–1 victories.

The following Ottawa Hockey Club players and staff were members of the Stanley Cup winning team.
