Lewis Hamilton led McLaren to a 1-2 finish at the Canadian Grand Prix on the weekend
Hamilton, who's first ever Formula 1 victory was at the Canadian circuit, is now at the top of the drivers' world championship.
Hamilton took the race lead from Red Bull's Mark Webber on the 50th of 70 laps.
McLaren team mate Jenson Button finished 2.2 seconds behind Hamilton, and Ferrari's Fernando Alonso was third.
Alonso was followed by Red Bull's Sebastian Vettel and Webber, Mercedes' Nico Rosberg, Renault's Robert Kubica and Toro Rosso's Sebastien Buemi.
Mercedes' Michael Schumacher finished 11th after starting 13th.
After starting the race on Bridgestone's super-soft compound tyres, Hamilton gave up the lead on the seventh lap to switch to the more durable medium compound. "We felt comfortable with the fact we'd have to stop in the first 10 laps," Hamilton said.
Webber, dropped from second to seventh on the starting grid because of a gearbox change, pitted for the first time on the 14th lap, electing to stay with the medium compound, and had little tread left when he hit the pits again on the 50th circuit.
Hamilton pitted for the final time on the 26th lap, putting on another set of medium-compound tyres. He rejoined the race in fifth place, quickly working his way to the lead.
"I really just tried to maintain the correct balance ... and get through traffic without losing too much time," Hamilton said. "It was very tricky, but we managed to deal with it."
