instance of hockey players playing publicly for pay occurred in Pittsburgh, Pennsylvania when a 1902 investigation by the Ontario Hockey Association (OHA) revealed that players on Pittsburgh-based teams received payment in 1901 and 1902, leading the OHA to ban any club from Pittsburgh from participating in their association, claiming there was "ample and undeniable proof" that clubs in Pittsburgh were "purely professional, paying straight salaries to their players." The 1903-04 Portage Lakes Hockey Club is regarded as the first team to pay each of the players on the team, while players in prior years in the Western Pennsylvania Hockey League were compensated via a mix of a small monetary payment and jobs in the Pittsburgh community, with the 30 players of the then four-team Western Pennsylvania Hockey League each receiving a weekly salary ranging from $10 () to $20 () per week in January of 1903, depending upon their agreements with James Wallace Conant, which resulted in the Ontario Hockey Association considering each of these teams as a "purely professional team". Beginning with the start of 1904 season the semi-professional Pittsburgh-based teams of the Western Pennsylvania Hockey League consolidated to become Pittsburgh Professionals and joined with the Houghton-Portage Lakes to become two of the original five teams of the International Professional Hockey League, marking the beginning of fully professional hockey in North America. By country Canada Professional leagues emerged from amateur leagues. In 1904, the predominantly U.S.-based International Professional Hockey League (IPHL) hosted the first Canadian professional team, the Canadian Soo. The league hired many amateur players away from Canada, causing the amateur leagues to convert to all-out professionalism or allow professional players in order to compete for the top players. The first Canadian professional league was the Manitoba Professional Hockey League (MPHL), formed in 1905 from member teams of the amateur Manitoba Hockey Association. The Eastern Canada Amateur Hockey Association (ECAHA), formed from prior amateur hockey leagues, emerged in 1906. The ECAHA allowed teams to have professional players from the start, despite its name. In 1907, the Ontario Professional Hockey League was formed. The competition for players increased salaries, a factor in the demise of the IPHL in 1907 and the temporary end of professional hockey in the United States. In 1908, the ECAHA became fully professional, as the ECAHA's amateur teams separated from the league and competed for the new Allan Cup, a new challenge cup instituted for
