Pirelli warns a wet Canadian Grand Prix could be "the perfect storm" for F1, posing unprecedented challenges for the new generation of cars. Unlike warm Miami, Montreal's expected low temperatures (11-12C) combined with the Circuit Gilles Villeneuve's long straights and few corners will make it exceptionally difficult to get and maintain temperature in the intermediate tires.

Drivers are concerned; Max Verstappen described it as "driving on ice" if tires are too cold. McLaren's Oscar Piastri added that the new power units dislike inconsistency, and wet conditions make consistency impossible, leaving engineers unsure how they will perform. This weekend could deliver a chaotic, unpredictable race, unlike anything F1 has seen with these current regulations.
