Football's most debated line in the sand just got redrawn — at least in Canada. The Canadian Premier League opened its 2025 season on Saturday as the first professional league to test FIFA's new "daylight" offside rule, and the sport's governing body is watching closely.
The concept is simple enough: an attacker is only offside if there's visible space — actual daylight — between them and the second-to-last defender. Level with the defender or tucked behind them? Onside. No more millimetre calls. No more freezing the frame on a shoulder blade.
Wenger's pet project finally gets a pitch
Arsène Wenger has been pushing this for years. As FIFA's chief of global football development, he finally has a testing ground — and he called the Canadian experiment "an important pilot." European leagues have so far refused to touch it, which makes the CPL's willingness to adopt the rule either brave or quietly desperate for relevance. Probably both, and that's not a criticism.
Atletico Ottawa head coach Diego Mejia took a measured view: "I see this as an opportunity to grow as a coach. It's going to give me more tools for the future." That's a tactically honest response. The rule shifts the calculus for defenders — if you're going to hold a high line, you'd better make sure you're not just a step ahead but clearly a step ahead. Expect some coaches to drop deeper and absorb pressure rather than gamble on tight margins.
Saturday's first match between reigning champions Ottawa and Forge FC also introduced video assistance to the league for the first time, using FIFA's Football Video Support model — a lighter version of full VAR. The first challenge took over five minutes to resolve and covered two possible offsides, a buildup foul, and a goalkeeper-striker collision that led to a penalty. It was unsuccessful.
Too early to judge, but the bones are there
A later offside check under the daylight rule didn't stop play at all. That's the whole point. Whether it holds up across a full season — and whether attackers start gaming the rule by staying pinned to defenders — is a different question entirely.
Critics aren't wrong to flag that cautious centre-backs could become the unintended winners here, retreating deeper to avoid giving up clear space behind them. That defensive recalibration could flatten attacking odds in a league already not known for high-scoring football.
What Canada has done, whether intentionally or not, is give global football a live laboratory that the Premier League, La Liga, and Serie A aren't willing to be. Wenger called it important. The first five-minute VAR review suggested the growing pains are real.
