The Canadian soccer league system, also called the Canadian soccer pyramid, is a term used in soccer to describe the structure of the league system in Canada. The governing body of soccer in the country is the Canadian Soccer Association (CSA), which oversees the system and domestic cups (including the Canadian Championship) but does not operate any of its component leagues. In addition, some Canadian teams compete in leagues that are based in the United States. Men League structure The Canadian soccer system consists of several unconnected leagues and it does not have promotion and relegation. Leagues in the Canadian system are classified as either professional, pro-am, or amateur. The Canadian Soccer Association (CSA) is the governing body for the sport in Canada and directly sanctions leagues that operate in more than one province. Leagues operating in a single province receive sanctioning from their provincial soccer association. Professional (division 1) The Canadian Premier League (CPL) is the top division of soccer in Canada. It is the only fully professional, and only fully national league in the system. Founded in 2019, the CPL is composed of eight teams and is sanctioned by the CSA. There are also three Canadian teams which play in Major League Soccer, the division 1 league sanctioned by the United States Soccer Federation, reflecting a longstanding practice of major Canadian sports franchises competing in American leagues. The Canadian clubs in this league are members of the CSA and compete in the Canadian Championship, rather than in the U.S. Open Cup, alongside clubs from the CPL and qualified lower division clubs. The three Canadian MLS clubs also compete in the Leagues Cup, a competition held between MLS and Liga MX division one clubs, as the North American regional competition within CONCACAF. The CPL does not take part in this competition. Pro-am (division 3) Pro-am (or semi-pro) soccer competitions in Canada are regionally-based due to its large geography and dispersed pockets of population. Teams playing in pro-am leagues are permitted to be composed of professional and amateur players. There are three of such leagues in Canada: League1 Ontario (L1O); the Première ligue de soccer du Québec (PLSQ); and League1 British Columbia (L1BC). They are based in the provinces of Ontario, Quebec and British Columbia, respectively, and are sanctioned by their relevant provincial soccer associations. There are 42 sanctioned teams playing in these leagues. These three leagues belong to the
