Kimi Raikkonen and Daniel Ricciardo have been give two-place grid penalties for not lining up correctly at the pit exit when Q2 restarted in Montreal.
Canadian Grand Prix qualifying had been red-flagged due to Felipe Massa's crash at Turn 3, and as the session resumed with less than two minutes to go, all 15 remaining drivers queued at the pit exit.
But several chose to spread out rather than sticking in line, and after the sessions the stewards summoned Raikkonen, Ricciardo, Jean-Eric Vergne, Sergio Perez and Pastor Maldonado over the incident.
Only Raikkonen and Ricciardo were penalised for not starting from the designated 'fast lane'.
Raikkonen loses just one place because his penalty was applied before Ricciardo's. He will start from 10th, with the Australian in 11th.
Raikkonen had been investigated over a similar potential transgression in Q3, but was not given any penalty for that instance.
His team-mate Romain Grosjean, who only qualified 19th, is already carrying a 10-place penalty for crashing into Ricciardo in Monaco.
