Kimi Antonelli leads George Russell in the only Formula 1 practice session for the Canadian Grand Prix after a chaotic Free Practice period marked by three red flags. The session is shortened by the interruptions, leaving teams with limited running and fewer opportunities to fully assess car performance under uninterrupted conditions. Antonelli records the fastest time, ahead of his Mercedes team-mate Russell, with Lewis Hamilton also featuring near the front of the order. Coverage of the session highlights Mercedes’ strong pace in the disrupted practice and points to an upgraded car configuration contributing to their performance. While details of the specific timing gaps are not provided in the reports, both sources agree on the top three order—Antonelli first, Russell second, and Hamilton among the leading cars—along with the overall picture of a session heavily affected by interruptions due to red-flag stoppages.
