Hamilton and both Aston Martins under FIA investigation after Canadian GP qualifying

The FIA stewards have a busy evening ahead after Canadian Grand Prix qualifying, with Lewis Hamilton and both Aston Martin drivers among those under investigation.

Hamilton, who was cleared earlier on Saturday for a Sprint race incident with Oscar Piastri, now faces a potential qualifying impede of Alpine's Pierre Gasly at Turn 8 during Q1.

Why it matters:

• Multiple high-profile investigations could lead to grid penalties that reshape Sunday's race order
• Hamilton's second brush with the stewards in one day highlights the fine margins of racing at Circuit Gilles Villeneuve

The details:

• Lewis Hamilton: Under investigation for potentially impeding Pierre Gasly at Turn 8 during Q1
• Fernando Alonso: Being investigated for a potential unsafe release after Franco Colapinto had to brake suddenly to avoid the Aston Martin at pit exit
• Lance Stroll: Faces a double investigation — one for an alleged unsafe release in Q1, and another for potentially impeding Nico Hulkenberg's Audi at Turn 5
• Sergio Perez: Under scrutiny for possible non-compliance with race director's instructions after Alonso took evasive action to avoid the slow-moving Cadillac at the final chicane

What's next:

The stewards will review all incidents this evening. Any penalties could significantly impact the grid for Sunday's Canadian Grand Prix, with Hamilton and the Aston Martin drivers potentially facing grid drops or other sanctions.
