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 Championship
The Canadian Championship is a club soccer competition organized by the Canadian Soccer Association. The championship determines Canada's entry in the annual CONCACAF Champions League. Fully professional Canadian soccer teams play in United States-based leagues. Prior to the creation of the official competition in 2008, there was no domestic competition to determine the best Canadian professional team (as Canada Soccer's Challenge Trophy only crowned the best amateur team). An unofficial Canadian Champion determined in the same manner as 2008–2010, a home-and-away series with the games taken from USL First Division (USL-1) regular season league games, was awarded by the Canadian national teams' supporters group, The Voyageurs. This unofficial Canadian Championship became less legitimate when Toronto was awarded a Major League Soccer (MLS) franchise to start play in 2007 in the USSF Division 1 MLS league above the USSF Division 2 USL-1 league. Toronto's USL-1 team self relegated, while the other two Canadian professional soccer teams did not play meaningful games against the new MLS team in 2007.
