 Note that in Canadian football (unlike American football), no scrimmage may start inside either one-yard line.In most cases, the non-penalized team will have the option of "declining" the penalty; in which case the results of the previous play stand as if the penalty had not been called.One notable exception to this rule is if the kicking team on a 3rd down punt play is penalized before the kick occurs; the receiving team may not decline the penalty and take over on downs.
