Professional football in Canada
Only one professional football league has a permanent presence in Canada: the Canadian Football League (CFL), an organization founded in 1958 to accommodate the ongoing trend of professionalism in the Canadian football ranks since the 1940s. The CFL, like most amateur Canadian football leagues, plays on a larger field using a rulebook with several significant rule differences compared to the game as it is played in the United States. The league is composed of two divisions and nine teams in most of the largest Canadian markets, with at least one team in each province between British Columbia (BC Lions) and Quebec (Montreal Alouettes) inclusive. The only presence in Atlantic Canada is a semi-regular series of games in Moncton (Touchdown Atlantic) and a smattering of earlier preseason contests. The CFL operates a two-week preseason beginning in June, an 18-game season from July to October, and a six-team playoff tournament, culminating in the Grey Cup on the fourth weekend of November.
List of Major League Soccer seasons
Major League Soccer is the premier professional soccer league in the United States and Canada. As of 2016, it consists of 20 teams: 17 in the United States and 3 in Canada. The league has played since 1996. Each year, it plays a league which determines entry into the playoffs. The league is divided into two conferences, the Eastern Conference and Western Conference. In 2000 and 2001, there was also a Central Conference. The team with the overall best regular-season record is awarded the MLS Supporters' Shield, one of three major domestic trophies in North American soccer (the others being the national championships—the Lamar Hunt U.S. Open Cup or the Canadian Championship—and the primary trophy: the MLS Cup league championship). In 2010 and 2011, the league played as a double round robin, with each team playing each other team one home and away—creating a balanced schedule. With a prime number of teams beginning in 2012, the league has moved to an unbalanced schedule weighted towards a team's respective conference.
