Three red flags and Mercedes 1-2 in messy Canadian GP practice

Formula 1 championship leader Kimi Antonelli topped the sole practice session at the Canadian Grand Prix on May 22, 2026, leading a Mercedes 1-2 with a time of 1m13.402s, which was 0.142 seconds ahead of teammate George Russell. The session was disrupted by three red flags, with the first caused by Liam Lawson's Racing Bulls car suffering suspected hydraulic issues, limiting him to just five laps. Lewis Hamilton's Ferrari was the fastest non-Mercedes car, finishing over seven tenths of a second behind Antonelli, as Mercedes debuted its first major upgrade of the 2026 season in Montreal.
