Canadian Football League
The regular season is 21 weeks long, with games beginning in mid-June and finishing by early November. The CFL's nine current teams are divided into two divisions: the East Division with four teams and the West Division, with five teams. Each team plays two games against each of the other eight teams, plus two divisional games with opponents rotating each season. With 18 regular season games being played, each team gets three bye weeks.
Major professional sports leagues in the United States and Canada
MLB, NBA, NFL, and NHL are commonly referred to as the "Big Four." Each of these is the wealthiest professional club competition in its sport worldwide, and along with the English Premier League they make up the top five sports leagues by revenue in the world. In addition, the sports of these four leagues were all developed in their modern forms in North America, and all except American football have become popular internationally. Because the leagues enjoy a significant place in popular culture in the U.S. and Canada, the best players from these leagues often become cultural icons in both countries. Each Big Four league, as well as Major League Soccer and Canadian Football League, averages at least 15,000 fans in attendance per game as of 2018.
