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.
Canadian soccer league system
By the mid 1960s, there were four major leagues across Canada including the Eastern Canada Professional Soccer League (1961–1967). From west to east, the other major leagues were the Pacific Coast Soccer League (British Columbia), the Western Canada Soccer League (Alberta, Saskatchewan and eventually Manitoba and British Columbia), and the National Soccer League (Ontario/Quebec). In 1968, Canadian soccer turned its attention to the cross-nation North American Soccer League that initially featured professional teams in Vancouver and Toronto. Over the next 15 years, the professional league also featured teams in Calgary, Edmonton, and Montreal.
