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 the top clubs from two other leagues: four from the Canadian Amateur Hockey League (CAHL) and two from the Federal Amateur Hockey League (FAHL). It was formed to maximize the revenues of a now popular spectator sport and help these amateur teams cope 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.
