Penalties never result in a score for the offence. For example, a point-of-foul infraction committed by the defence in their end zone is not ruled a touchdown, but instead advances the ball to the one-yard line with an automatic first down. For a distance penalty, if the yardage is greater than half the distance to the goal line, then the ball is advanced half the distance to the goal line, though only up to the one-yard line (unlike American football, in Canadian football no scrimmage may start inside either one-yard line). If the original penalty yardage would have resulted in a first down or moving the ball past the goal line, a first down is awarded.
In which North American style of football is the line of scrimmage never inside the one-yard line? (If the question is unanswerable, say "unanswerable")
Canadian
