 With 18 regular season games being played, each team gets three bye weeks.The most popular featured week in the CFL season is the Labour Day Classic, played over the course of the Labour Day weekend, where the matchups feature the first half of home-and-home series between the traditional geographic rivalries of Toronto–Hamilton (a rivalry which began in 1873), Edmonton–Calgary (see Battle of Alberta), Winnipeg–Saskatchewan, and Ottawa–Montreal.In years that Ottawa or Montreal were not in the league, BC would play against one of these teams.
