CANADIAN FOULS:

1. Illegal Procedure (Offense) - 3- and 4-point stance players moving/lifting before the snap.
2. Offside (Defense) - crossing LS.
3. Offside (Defense) - making contact with o-line.
4. Offside (Offense) - WR embarassing himself going downfield early and rather far.
5. Time Count (Offense) - taking longer than 20s to snap the ball after the RFP.
6. IE/OC/UR/RP (Either) - if one of these happens before the snap, kill the play, assess the penalty.
