Overview
- Tensions between Mercedes teammates boiled over in Montreal where repeated close battles in the Sprint race carried into the Grand Prix and prompted on‑radio warnings from the team.
- Mercedes boss Toto Wolff said the team drew up new guidelines after the Sprint to clarify how the drivers should race one another and warned team orders could follow if they ignored radio instructions.
- Russell retired from the lead with a power‑unit/battery failure, which released Antonelli to win and extend his championship advantage to 43 points over his team‑mate.
- After his retirement Russell angrily threw his headrest onto the track and was noted by FIA stewards; commentators reported a €5,000 fine suspended for 12 months for the incident.
- The result hands Antonelli clear favourite status but raises fresh questions for Mercedes about managing driver freedom, safety and reliability as the team heads to Monaco and the longer European season.
