rules to play canoeing

Substitutions can take place at any time during the game. A player may be substituted once they and all their kit have completely left the pitch at their own goal line. The only exception to this rule is when substituting a capsized player who has left their kayak this player may be substituted at the next break in play as long as all their kit has been removed from the pitch.
Play does not stop for a capsized player unless they are causing an obstruction or are in a dangerous position.An illegal substitution is penalised with a yellow card the team play with one less player for the duration of the yellow card.
