Canadian Football Rules Reference

The game of flag football shall be governed by the playing rules, regulations and definitions as written in this book.
Whenever changes in the playing rules are permitted by league or tournament organizers, these options should be provided in writing to each participating team and official prior to the season or tournament.
The Referee is responsible for the adherence to the rules and regulations by both teams and all officials. The Referee will make the final decision on any on-field situation not covered by the rules and regulations. All officials should strive to maintain a safe environment for the players.
At any time during the game, if a referee feels that continuing to play the game at hand may jeopardize a player's safety, the official may remove that player from the game immediately. An explanation should be included on the game sheet as to the reason why the player was removed. A referee's decision in this matter is final and cannot be challenged by the player affected or his/her teammates. Teams/players wishing to protest an official's decision must do so in writing to the League Executive within 48 hours of the conclusion of the game.
A participant (player or official), suffering from a wound or laceration, where oozing or bleeding occurs, must leave the playing field until appropriate medical treatment is administered. The participant may return to the playing field only after the bleeding has stopped and the affected area or the open wound has been completely and securely covered. The referee must approve the participant's return to the playing field.
If a player or official has any part of his/her uniform or equipment saturated with blood, the uniform must be cleansed or changed immediately. "Saturated" being defined as the amount of blood being sufficient to soak through the garment and onto the skin or such that the blood would easily be transferred to another participant.
