In 1906, Ottawa defeated OHA champions Queen's University and FAHL champions Smiths Falls in Stanley Cup challenges. However, Ottawa tied the Montreal Wanderers for the ECAHA regular season championship. To decide the ECAHA championship and the Stanley Cup, the Senators played a two-game total goals series against the Wanderers in March 1906 and lost. The 1906 hockey season ended with the Wanderers as the Stanley Cup champions. The Hockey Hall of Fame recognizes both Ottawa and the Wanderers as champions for that year,[67] as does the NHL.[68]
