Canada GP FP1 descended into chaos on Friday at Circuit Gilles Villeneuve. Three red flags tore through the session and stripped every team of critical setup data. Kimi Antonelli emerged fastest with a 1:13.402 on soft tyres. Still, the disruption left the entire grid blind heading into Sprint Qualifying. Tyre behaviour and long-run pace remain unknown across the field going into the shootout.
Esteban Ocon triggered the final and most damaging red flag. The Haas driver crashed heavily and returned to the pits with his front wing torn completely off. Fortunately, the wing absorbed the majority of the impact and Ocon walked away uninjured. The stoppage ended meaningful running for the rest of the field. A green-flag restart with under a minute remaining gave teams almost nothing to work with.

Liam Lawson triggered the first stoppage after parking on track with a power steering failure. Alexander Albon then brought out the second red flag after clipping the wall. Consequently, teams lost a large portion of their practice time before the session reached its midpoint. The damage proved especially costly on a Sprint weekend, where FP1 is the only practice session before qualifying.
Meanwhile, mechanical concerns hit several drivers across the session. Max Verstappen reported over the radio that his Red Bull was giving him “weird snaps” on downshifts. Oscar Piastri locked up badly into the final chicane and diverted down the escape road. The incident left him with front tyre flatspots. George Russell also spun at Turn 1 and tapped the wall but returned to the garage without serious damage.
Furthermore, the stewards confirmed a post-session investigation into Lawson following Canada GP FP1. The Racing Bulls driver faces charges over a Clutch Disengagement System failure. The system failed to operate for marshals when his car stopped on track. Safety regulations require the system to function correctly at all times. A time penalty or grid drop is possible once the stewards complete their review.
Crucially, the three red flags erased almost all long-run data across the field. Tyre degradation rates remain a mystery for every team heading into Saturday. Canada GP FP1 ultimately confirmed one thing above all else. Antonelli is the fastest driver on track this weekend. The championship leader carries momentum into Sprint Qualifying, but the session raised more questions than answers for the rest of the grid.
