The Canadian Professional Hockey League, also known as Canpro, was a minor professional hockey league founded in 1926. After three seasons, it became the International Hockey League in 1929. The name was then given to a new league of IHL farm teams which operated in the 1929-30 season.
The initial meeting to organize a new league was held on June 27, 1926 in Hamilton, Ontario. The governing body for amateur hockey in Ontario, the Ontario Hockey Association, had been cracking down on teams that induced players to move from other areas in violation of the league's residency requirements. In mid-June, the OHA refused to certify over 20 players who had changed residences. Windsor alone had eight players who were denied OHA certification.
In response, and also driven by the recent expansion of professional hockey in North America, seven OHA senior teams met to discuss forming a minor professional league that would be affiliated with the National Hockey League. Brantford and Toronto were at the initial meeting, but had to bow out, and the remaining five teams became the inaugural members of the CPHL: Hamilton, London, Niagara Falls, Stratford and Windsor. Charles King of Windsor was made league president on August 4 and served in that role for all three seasons the CPHL operated.
After the 1927-28 season, all the players on the Hamilton Tigers were purchased by the new Buffalo Bisons (a team based in Fort Erie), and an entirely new team played in Hamilton. Teddy Oke's Kitchener Millionaires moved to Toronto to take the place of the Toronto Ravinas which disbanded in 1928. Oke sold the franchise rights to Kitchener to a new owner, who created the Kitchener Flying Dutchmen. The team included players from the Millionaires that did not move to Toronto.
