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.
Sports in North America
The men's professional soccer league systems in both the U.S. and Canada instead primarily use the closed, franchise model which primarily always has the same teams playing. Major League Soccer (MLS) represents the highest level, while the second level consists of the North American Soccer League (NASL) and the United Soccer League (USL). Although MLS, NASL, and USL all have teams in both countries, they are only sanctioned by the United States Soccer Federation (USSF), the governing body of soccer in the United States. The Canadian Soccer Association, the governing body in Canada, instead sanctions two third-level all-Canadian leagues at the third level: League1 Ontario and Première Ligue de soccer du Québec. There are no USSF sanctioned leagues at the third level. For women' professional soccer, the National Women's Soccer League is at the top level, and National Women's Soccer League and Women's Premier Soccer League are at the second level. College soccer is played both in the U.S. and Canada, with top players often going on to play professional.
