Major professional sports leagues in the United States and Canada
The Canadian Football League is the highest level of play in Canadian football. The league was organized in 1956 as a cooperative agreement between two regional leagues, the Big Four (which dated to 1907) and the WIFU (which was founded in 1936), and became independent from Football Canada in 1958. The league now consists of nine teams, all based in Canada. The Grey Cup is awarded annually to the champion every November and is the highest attended sporting event in the nation. The oldest extant teams, the Hamilton Tiger-Cats and the Toronto Argonauts, trace their origins to the late 1860s and early 1870s, which ranks them amongst the oldest professional sports teams of any kind still in existence on the continent. The CFL attempted an expansion into the United States in cities that had no NFL team between 1993 and 1995, though the expansion teams all either folded or relocated to Canadian cities.
United States Football League
There were plans to establish four franchises in Canada prior to the inaugural season, located in Vancouver, Edmonton, Montreal and Southern Ontario (specifically at Ivor Wynne Stadium in Hamilton, Ontario). The proposal was pushed by John F. Bassett, the Canadian who would go on to own the Tampa Bay Bandits USFL team. However, Senator Keith Davey warned that the Canadian government would act to protect the Canadian Football League from competition. The Canadian Football Act had been proposed, but not approved, when Basset had tried to establish the Toronto Northmen in the World Football League in 1974. Such legislation would have banned US football leagues from playing in Canada. In particular, Montreal's CFL team, the Concordes, was on precarious financial ground, having just been established to replace the recently folded Alouettes. This led Bassett to drop the idea.
