The McLaren driver Lewis Hamilton timed his final run to perfection to snatch pole position for the Canadian Formula One Grand Prix and halt Red Bull's domination of qualifying this season.
With barely seconds to spare and hardly any fuel left in his car's tank, the Briton roared around the Circuit Gilles Villeneuve in a slick one minute 15.105 seconds to claim his third straight pole in Montreal and shatter Red Bull's hopes of an eighth consecutive pole this year.
Australia's Mark Webber, the championship leader who had started at the front of the grid in the three previous races, had to settle for second place while his German team mate Sebastian Vettel was third.
Spain's Fernando Alonso was fourth for Ferrari with Hamilton's team mate and reigning world champion Jenson Button fifth after just sneaking into the final stage of qualifying with a blistering last lap in the second session.
