The Canadian Premier League (CPL) has become the first professional soccer league to trial the 'daylight offside rule', a change long advocated by FIFA's Arsène Wenger. The rule deems a player onside as long as any part of them remains in line with the second-to-last defender, a shift from the current strict interpretation where attackers cannot be even an inch ahead.
Pacific FC striker Alejandro Díaz scored the first professional goal under the new rule, later learning he had made history. The CPL introduced the trial in April for the 2026 season, with FIFA's support. Commissioner James Johnson believes the change brings clarity and encourages more goals, which fans enjoy.
Supporters like Díaz and former Canadian international Mike Sweeney praise the rule for favouring attackers and reducing controversial fine-margin offside calls. However, defenders and goalkeepers, such as Halifax Wanderers' Thomas Meilleur-Giguère, express concern that it undermines defensive tactics developed over years.
The International Football Association Board remains noncommittal, while FIFA president Gianni Infantino has expressed support. The CPL is also trialling Football Video Support, allowing coaches two video review requests for clear errors in match-changing incidents.
