The 2011 Canadian Grand Prix (formally the Formula 1 Grand Prix du Canada 2011) was a Formula One motor race held on 12 June 2011 at the Circuit Gilles Villeneuve, in Montreal, Quebec, Canada. It was the seventh race of the 2011 Formula One World Championship and the 48th Canadian Grand Prix. McLaren driver Jenson Button won the 70-lap race starting from seventh position. Sebastian Vettel, who started from pole position, finished second for Red Bull Racing with teammate Mark Webber finishing third.
The race began behind the safety car, and, once it returned to the pit lane, Vettel built a lead over Fernando Alonso. A second safety car deployment caused by the collision of Button and teammate Lewis Hamilton closed the time gaps between cars, but Vettel retained the lead. By lap 26, increasingly heavy rain led to the race's suspension, before it was restarted over two hours later. Button was involved in another collision on lap 37, which led to Alonso's retirement and Button falling to last place. Over the remainder of the race, he moved from twenty-first place to first, passing Webber and Michael Schumacher, who had started fourth and eighth respectively, for second place on lap 65, and Vettel on the final lap.
The victory was Button's first of the season, and put him into second place in the World Drivers' Championship, sixty points behind leader Vettel, who had extended his lead despite finishing second. Webber remained in third, and Hamilton's retirement meant he slipped to fourth. In the World Constructors' Championship Red Bull extended their lead to 65 points from McLaren, with Ferrari a further 85 points behind. At over four hours (including a red flag period) the race set the record as the longest in Formula One history.
Background The 2011 Canadian Grand Prix was the seventh of 19 rounds in the 2011 Formula One World Championship and took place at the Circuit Gilles Villeneuve, Montreal, Quebec on 12 June 2011. The Grand Prix was contested by twelve teams, each of two drivers. The teams, also known as constructors, were Red Bull Racing, McLaren, Ferrari, Mercedes, Renault, Williams, Force India, Sauber, Toro Rosso, Lotus, HRT and Virgin. Tyre supplier Pirelli brought four different tyre types to the race: two dry compounds, the yellow-banded soft "primes" and the red-banded super-soft "options"; and two wet-weather compounds, the intermediate and full wet. The drag reduction system (DRS) had two activation zones for the race; one was on the straight between turns 11 and 13, and the second on the start/finish straight from the final to first corners.
Going into the race, Red Bull driver Sebastian Vettel led the World Drivers' Championship with 143 points, ahead of Lewis Hamilton on 85 points and Mark Webber on 79. Jenson Button was fourth with 76 points while Fernando Alonso was fifth on 69 points. In the World Constructors' Championship Red Bull were leading with 222 points, McLaren and Ferrari were second and third with 161 and 93 points respectively, while Renault with 50 and Mercedes with 40 points contended for fourth place. Red Bull and Sebastian Vettel had so far dominated the championship, winning five out of the six previous races, with Lewis Hamilton winning the . Championship contenders Webber and Button had gained one second-place finish each, and Alonso, Vitaly Petrov and Nick Heidfeld had achieved third place podium finishes.
Prior to the event Virgin Racing announced they would end their partnership with Wirth Research, the company responsible for designing and developing the team's racing cars. In order to cut costs, Wirth Research had designed the cars exclusively using computational fluid dynamics, and unlike their competitors Wirth had not utilised a wind tunnel. The approach was not successful as the team had failed to qualify higher than 20th so far in the season, leading to the partnership's conclusion. Virgin Racing's CEO Andy Webb, who had aims to challenge for a podium position at the inaugural Russian Grand Prix, expressed that ending the partnership would mean "that the team will take greater control of its own destiny". Wirth Research would continue to develop the car until the end of the 2011 season, while Virgin Racing would up their own technical department under the control of former Renault Director of Engineering Pat Symonds.
Several teams made major technical updates to their cars for the Grand Prix. McLaren and Ferrari altered the brake ducts on their cars, improving the cooling to manage the high brake temperatures encountered in Montreal. Ferrari and Mercedes revised their rear suspension layouts, while Red Bull brought a new front wing optimised for lower downforce. Renault and Williams brought new rear wings, which were designed specifically for low-downforce circuits such as Circuit Gilles Villeneuve, where the race was held.
Practice
Three practice sessions were held before the race; two 90-minute sessions on Friday and one lasting an hour on Saturday. Nico Rosberg was the fastest driver in the first practice session, ahead of Alonso and Mercedes driver Michael Schumacher. Vettel caused the session to be suspended after crashing into the circuit's "Wall of Champions" on the last corner, heavily damaging his car. After the morning session Sergio Pérez, who had suffered from concussion after a crash at the previous race, withdrew from the Grand Prix. Although he had passed the FIA's medical examination, Pérez said that "I only want to drive when I'm a hundred per cent well. I need some more time to recover". He was replaced by McLaren's reserve driver Pedro de la Rosa, who had competed for Sauber in . Alonso was fastest in the second session, ahead of Vettel, Massa and Hamilton – although the McLaren driver received a puncture midway through practice. The session was disrupted by incidents as Kamui Kobayashi and Jérôme d'Ambrosio struck the barriers – both accidents requiring a suspension as marshals cleared the track of debris – and Adrian Sutil's Force India broke its suspension in a crash at turn 7. The third session on Saturday morning saw Vettel fastest, ahead of Alonso, Rosberg and Massa. A KERS failure on Webber's RB7 prevented him from participating. A crash by de la Rosa in the final minute brought out a red flag, and the session was prematurely ended due to the limited time remaining.
Qualifying The qualifying session on Saturday afternoon was split into three parts. The first part ran for 20 minutes and eliminated the cars from qualifying that finished the session 18th or lower. During this session, the 107% rule was in effect, which necessitated each driver set a time within 107% of the quickest lap to qualify for the race. The second part of qualifying lasted 15 minutes and eliminated cars that finished in positions 11 to 17. The final part of qualifying determined the positions from first to tenth, and decided pole position.
Vettel achieved his sixth pole position of the season, and his first at the Circuit Gilles Villeneuve, with a time of 1 minute and 13.014 seconds. He was joined on the front row of the grid by Alonso, with teammate Massa in third, giving Ferrari their best qualifying performance of the season. Webber had not been able to use his car's KERS and qualified fourth, four-tenths of a second behind Vettel. Hamilton and Button qualified in fifth and seventh respectively and McLaren blamed the slow pace on too high levels of downforce on the high-speed circuit. The Mercedes drivers qualified in sixth and eighth, and Heidfeld and Petrov completed the top ten. Paul di Resta was in 11th position, ahead of fellow rookie Pastor Maldonado and Kobayashi. Sutil struggled with grip throughout the session and was 14th; following him were Sébastien Buemi, Barrichello and de la Rosa. Jaime Alguersuari qualifying in 18th complained of insufficient grip and brake balance, and at the back of the grid were the Lotus, HRT and Virgin drivers. D'Ambrosio did not qualify after failing to set a time within 107% in the first qualifying session. However the stewards allowed him to race, having considered he was using a new chassis after an accident in Friday practice, where he had set faster lap times.

Race
The track was wet before the race, as rain showers had hit the area throughout the day. The race was due to start at 13:00 local time (UTC−4), and heavy rain was expected to arrive an hour into the race. The air temperature ranged between , with the track temperature between . Standing water on the track, which was causing heavy spray and impairing visibility, meant that the race would start behind the safety car and all cars would use the full wet tyres. Alguersuari would start the race from the pitlane, as he modified his Toro Rosso's set-up to optimise the car for the wet conditions.
The race began behind the safety car, with no formation lap, and despite the slow speed drivers struggled for grip on the wet surface. The safety car came into the pit lane after five laps, and the cars were allowed to overtake. Vettel retained first place withstanding Alonso's attempts to pass, while behind Hamilton and Webber collided at the first corner – dropping the drivers to seventh and fourteenth respectively. Button lost fifth place mid-lap after running wide, losing two places to Schumacher and Hamilton. At the end of the first racing lap, di Resta had moved up to eighth position, followed by Heidfeld and Kobayashi, who made three places off the grid. Vettel extended his lead over the next lap, while the positions behind continued to change. Kobayashi had improved to eighth and Webber recovered to twelfth, while di Resta fell back to thirteenth. Hamilton lost sixth position running wide on a failed overtaking move on Schumacher, and fell behind Button. He attempted an overtake on the pit straight, but the two drivers collided and Hamilton hit the pit wall. The accident caused Hamilton's retirement, which prompted a safety car deployment at the end of lap eight.
