Canadian football

Canadian football is football generally played in Canada and follows much the same general rules as American Football. Compared to American football, the field is slightly longer and wider, 110 by 65 yards (101 by 59 m) rather than 100 by 53 1/3 yards (91 by 49 m), and the endzones are 10 to 15 yards deeper. There are also only 3 downs instead of 4, and the field goal posts are at the front of the endzone instead of the back. There are 12 players per team on the field during play. More than one player may be in motion before the snap of the ball and the rules are less strict about players position relative to the line of scrimmage.
