Sebastian Vettel snatched pole position at the Canadian Grand Prix for the third year in a row, pipping Lewis Hamilton in a frantic wet qualifying session to end Mercedes’ run at the front of the grid.
The triple world champion kept his cool in the treacherous conditions to safely steer his Red Bull around the Montreal street circuit in a fastest time of one minute 25.425 seconds for his 39th career pole.
In a repeat of last year’s qualifying, the 25-year-old German was joined on the front row of the grid by Britain’s 2008 world champion Hamilton, who was just 0.087 seconds behind.
Finnish rookie Valtteri Bottas was third for Williams, the highest grid placing of his short career and a major boost for a team suffering their worst start to a season with no points in six races so far.
Monaco winner Nico Rosberg, who had taken pole at each of the last three rounds of the championship, will line up fourth for Mercedes.
Red Bull’s Australian Mark Webber and Ferrari’s Fernando Alonso shared the third row while Lotus’s Kimi Raikkonen, second in the championship standings behind Vettel, qualified ninth.
Despite his run of poles in Canada, Vettel has yet to win a Formula One race in North America despite his domination elsewhere but gave himself another great opportunity.
With light rain falling and puddles on parts of the track, none of the drivers were able to drive flat out, struggling just to stay on the slippery Circuit Gilles Villeneuve, one of the most demanding courses in Formula One because of its super-fast long straights and slow, tight corners.
Most drivers, including Vettel, ran off course at some point during the three-stage qualifying session, which was halted in the middle when Ferrari’s Felipe Massa slammed sideways into a barrier.
Felipe Massa also crashed heavily in Monaco practice and the race, qualified 16th.
The day got off to an ominous start when the final practice session was reduced from 60 minutes to 30 after a car crashed into a fence during a support race, forcing maintenance staff to repair the barrer before the F1 cars could run.
Vettel had taken pole in the first two races this season, in Australia and Malaysia, but the Red Bulls had been unable to keep up with Mercedes in the four races since.
A three-time winner in Canada with his previous team McLaren, Hamilton had loomed as the man to beat for pole but the Englishman was unable to get enough heat in his tyres to generate the speed he needed.
McLaren failed to make the final phase of qualifying on Saturday with Jenson Button, a winner in Canada two years ago from last place after a re-start, qualifying 14th and missing the top-10 shootout.
While there was disappointment for McLaren and Ferrari, the struggling Williams team were in high spirits after Bottas weaved his way through the traffic to qualify third.
