The Canadian Football League or CFL is a professional sports league located in Canada. The CFL is the highest level of competition in Canadian football, a form of gridiron football closely related to American football. Its eight teams, which are located in eight cities, are divided into two divisions of four teams each - the East Division and the West Division. The league's 19-week regular season runs from late June to early November; each team plays 18 games with one bye week. Following the regular season, the three teams with the best records in their division (except if the fourth place team in one division has a better record than the third place team in the other division, the team with the better record makes the playoffs and "crosses over" to the other division's playoff) will compete in the league's three-week divisional playoffs, which culminate in the late-November Grey Cup championship, the country's largest annual sports and television event.
