Canadian football is a form of gridiron football played in Canada in which two teams of 12 players each compete for territorial control of a field of play 110 yards (101 m) long and 65 yards (59 m) wide[1] attempting to advance a pointed prolate spheroid ball into the opposing team's scoring area (end zone). In Canada, the term football usually refers to Canadian football and American football collectively, or either sport specifically, depending on the context. The two sports have shared origins and are closely related but have significant differences. In particular, Canadian football has 12 players on the field per team rather than 11; the field is roughly 10 yards wider, and 10 yards longer between end zones that are themselves 10 yards deeper; and a team has only three downs to gain 10 yards, which results in less offensive rushing than in the American game.
