The CHA was formed by three teams from the Eastern Canada Hockey Association: Ottawa, Quebec, and the Montreal Shamrocks.
The CHA rejected applications from Wanderers and other teams who then formed their own league, the National Hockey Association (NHA).
The backers of the NHA included some very successful businessmen who had much deeper pockets than the CHA owners.
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, Ontario, champions of the Ontario Professional Hockey League and prevailed with 12–3 and 3–1 victories.
During the NHA season Ottawa as Cup champion played a challenge against Edmonton in addition to their regular schedule.
