The Canadian Premier League is currently trialing the 'daylight' offside rule, a significant change to the traditional offside law. Under this new interpretation, a player is only considered offside if there is clear daylight between them and the second-last defender when the ball is played.
The first goal under this rule was scored by Pacific FC's Alejandro Díaz during a hard-fought 2-2 draw with the Halifax Wanderers. Díaz's goal, which would have been ruled offside under the old interpretation, stood after video review confirmed that there was no gap between him and the defender.
The trial is part of a broader effort to simplify the offside rule and increase attacking play. Further matches will provide more data on the rule's impact.
