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.
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.
