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.

Other notable leagues include Major League Soccer (MLS) and the Canadian Football League (CFL), both of which compare to the other four leagues in certain metrics but not in others. Every major league, including the CFL and MLS, draws 15,000 or more fans in attendance per game on average as of 2015. Therefore, this list includes a ranking by teams in the Big Four (B4), and a separate ranking also including teams in the CFL and MLS, called the Big Six (B6).
