Differences Between Canadian and American Football
American and Canadian football both descended from rugby and began in Canada as a game played between British soldiers garrisoned in Montreal. The soldiers played a series of games against students at McGill University. McGill played several games against Harvard in 1874 and a tradition was born. Despite their mutual origins, the Canadian and the American game developed differently and now have substantially different rules and regulations.
The biggest difference between Canadian and American football is the size of the playing field. In Canada, football fields are 110 yards long and 65 yards wide. In America football fields are 100 yards long and 53 and 1/3 yards wide. The goal posts in Canadian football are placed at the front, rather than the back of the end zone which is also deeper in Canadian football than American.
Canadian football teams have twelve players as opposed to the eleven on American teams. Because the same number of players is required at the line of scrimmage in both games, this results in an extra backfield player on Canadian teams. This means that the typical Canadian offensive setup has two slot backs instead of a tight end and on defense, two defensive halfbacks and one safety instead of two safeties as is typical in the American game.
