McLaren explain the logic behind their intermediate gamble in Canada

It was a gamble that looked like genius for exactly one lap. When Lando Norris and Oscar Piastri lined up for the Canadian Grand Prix on intermediate tyres, the team was chasing a safety advantage in damp conditions. While Audi, Cadillac, and one Williams entry made similar calls, those cars were safely buried in the field, away from the pressure of the front. For McLaren, the decision ultimately caused their race to unravel.

The logic was sound at the moment it was forced. Between the anthem and the five-minute call to fit tyres, the rain intensity and greasy track surface suggested the inters were the only way to survive the opening lap. Norris even used the extra grip to jump into the lead, pulling a two-second gap in one lap. But then the sky cleared, and the track dried rapidly.

Adding to the frustration was the chaotic start procedure, as multiple formation laps—triggered by an issue for the Racing Bulls machine of Arvid Lindblad—drained vital minutes while the track surface transformed. Team Principal Andrea Stella maintains the call was a collective, logical choice at the time, even if hindsight paints a different picture. As Norris noted, it is a tough pill to swallow, but one they have to take on the chin and learn from.
