Canadian Premier League to Trial FIFA Offside Rule in 2026

The Canadian Premier League will become the world's first professional soccer competition to trial a new offside rule starting April 4, 2026, in a pilot program approved by FIFA and the International Football Association Board.

The initiative, known as the daylight principle and promoted by Arsène Wenger, FIFA's chief of global football development, aims to shift the balance toward attackers by eliminating marginal offside decisions. Under the rule, an attacking player will be considered onside if any part of their body that can legally score a goal—excluding hands and arms—remains level with or overlaps the second-last defender. Offside will be called only when there is clear separation, or "daylight," between the attacker and the defender. This approach seeks to reduce controversies over tiny margins, such as a shoulder or toe ahead, which have become common with video assistant referee technology in top-tier matches.

The trial marks a significant step in evaluating potential changes to soccer's laws, with the league serving as FIFA's primary testing ground. Officials will monitor its effects on attacking play, defensive strategies, goal tallies, and overall match flow. Data...
