The Canadian Football League is a professional sports league in Canada. The CFL is the highest level of competition in Canadian football. The league consists of nine teams, each located in a city in Canada. They are divided into two divisions: four teams in the East Division and five teams in the West Division. As of 2024, it features a 21-week regular season in which each team plays 18 games with three bye weeks. This season traditionally runs from mid-June to early November. Following the regular season, six teams compete in the league's three-week playoffs, which culminate in the Grey Cup championship game in late November. The Grey Cup is one of Canada's largest annual sports and television events. The CFL was officially named on January 19, 1958, upon the merger between the Interprovincial Rugby Football Union or "Big Four" and the Western Interprovincial Football Union.
