Hamilton leads Vettel by 14 points in the standings after six races and will be determined not to allow him to cut substantially into that cushion.
Sebastian Vettel won the Canadian Grand Prix on Sunday as Australian Daniel Ricciardo finished fourth in a weird ending to the race. "It's great when you have a session like that".
Vettel managed to place a 1:10.764s on his final run in qualifying to beat Valtteri Bottas and Max Verstappen in the race for pole, with the German saying starting on the front row in Canada is special for the Italian team. The Scuderia are the most successful team at the Circuit Gilles Villeneuve with 11 wins but they had not had a victory here since Schumacher won in 2004.
Stroll, 19, was in is second Canadian GP. Hamilton has won the Canadian race six times, including the previous three. The Briton has won the last three on the track that seems to suit the Mercedes auto with its heavy braking after long straightaways and tight chicanes.
Hamilton, who had engine problems in the race, said: "It could have been a lot worse. I told them I don't think the race is over yet", said Vettel, who confirmed on the counter in his auto and with his team that he was only completing his 69th of the scheduled 70 laps. It was the seventh race on the engine so it's saw its life. He and Ferrari executed their race to perfection, took the lead in the title race and have left Hamilton and Mercedes with much to consider before racing resumes in France in a fortnight.
"I hope they don't go to two engines next year because it's just going to get ridiculous", he said.
He admitted: "We were coming to Montreal expecting our auto to be really strong and we are leaving Montreal seeing that we haven't been where we thought we should be. We need to keep applying the pressure, we didn't this weekend but I'm really going to make sure we come back stronger at the next race".
"With the long straights it's hard to fight for pole position".
"Like every grand prix there's not one person to dedicate it to", said Vettel.
Kimi Raikkonen in the other Ferrari and Monaco victor Daniel Ricciardo are in the third row.
Vettel had no such trouble, leaving the jostling behind him as he steered through the 4.36-kilometer track named for the Ferrari driver and Montreal native who earned his first Formula One victory here 40 years ago.
