The rules are essentially the same. It's the make-up of the game that is different.
The Canadian Football field and end zone is larger 110 yd by 65 yd and the end zone is 20 yd by 65 yd. (In comparison the American football field is just 100 yd by 53 1/3 yd and the end zone is just 10 yd deep.)
Canadian Football has 12 players (instead of 11) and they are allowed just three downs to make a first down.
In Canadian Football:
-The defensive line must be at least one yard from the line of scrimmage.
-The goal posts are on the goal line rather than the end line.
-Any player in the offensive backfield can be in motion in any direction before the snap of the ball.
-Their is no fair catch rule on punts, however the kicking team must be at least 5 yards away from the catcher at the time the ball is caught or receive a "no yards" penalty.
Size of the field 100 vs 110 yards
Number of players 11 vs 12
Number of downs 4 vs 3
