The Eastern Canada Amateur Hockey Association (ECAHA) was a men's amateur, later professional ice hockey league in Canada that played four seasons. It was founded on December 11, 1905 with six clubs: four from the Canadian Amateur Hockey League and two from the Federal Amateur Hockey League(FAHL), to bring together the top teams of both leagues. It was formed to enhance the revenues of a now popular spectator sport and help it cope in Canada with professionalism in the sport. The league would shed its amateur status for the 1908 season, leading to the split between Canadian amateur ice hockey teams playing for the Allan Cup, and the professionals playing for the Stanley Cup. The league would itself dissolve in 1909 over a dispute between team owners over business issues, and the emergence of the Renfrew Millionaires.
The CAHL held its regular meeting on December 9, 1905. At that meeting it was decided that amalgamation with the FAHL should be attempted. On December 11, it was announced that the amalgamation would form a new league, the ECAHA. The CAHL was discontinued, but the FAHL would continue. The first executive was elected:
- G. P. Murphy, Ottawa (1st vice-president)
- Dr. Cameron, Montreal (2nd vice-president)
- James Strachan, Wanderers ( Secretary-treasurer)
However on December 20, the vice-president titles were abolished and the Secretary-treasurer position was given to William Northey of the Montreal Arena Company.
A silver championship trophy was donated by the Montreal Arena Company. After the Wanderers won it in 1906 through 1908, they were given the trophy permanently, a condition engraved in the silver of the trophy. The trophy is now on permanent display in the Hockey Hall of Fame in Toronto.
From the start, the league allowed teams to openly use professional players. The players who were professionals had to be printed publicly. In 1908, the purely amateur Montreal Victorias and Montreal Hockey Club teams left the league. The league became a professional-only league, leading to several amateurs retiring from their teams. In significance of the change the league was renamed the Eastern Canada Hockey Association.
In November 1909, the league dissolved over the plans of the Wanderers to move to a smaller arena. The three other teams announced that they were leaving the ECHA, creating the Canadian Hockey Association (CHA). The Wanderers, formed a competing league, the National Hockey Association (NHA). The CHA lasted less than two weeks and in January 1910 it merged with the NHA.
