Yahoo - Unlike American football, Canadian football holds that once a punt travels more than 10 yards downfield, the kicking team can recover the free ball and regain possession. In this way, Canadian punts are essentially just like American kickoffs. However, Canadian football holds that on scrimmage kicks (i.e., punts and missed field goals), the returning team can respond by immediately punting the ball back to the other team, creating a free-for-all where whichever team gets to the ball first will retain possession.
Look at us! Look at us! We’re Canada and we have stupid weird wacky rules for football! Hey Canada, Grow up.
