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.

In the late 1940s and 1950s, the Canadian Football League (CFL) and the U.S. National Football League (NFL) operated on roughly equal footing financially, with even some U.S.-born star players joining CFL teams. The situation changed along with the rise of the American Football League (AFL) founded in 1959. By the end of the 1960s, revenue from the U.S. television market and absorption of the AFL helped the NFL become much more successful than its Canadian counterpart. By the 1980s, the CFL became virtually unknown outside of Canada. Attempts to promote the CFL included the failed CFL USA experiment in the 1990s. In 2009, a record number of 6.1 million viewers watched the CFL's annual Grey Cup championship game, while 151.6 million viewers watched the NFL's annual Super Bowl championship game that same year.
