Tyre supplier Pirelli brought four different tyre types to the race: two dry compounds, the soft 'primes' and the super-soft 'options' and two wet-weather compounds, the intermediate and full wet. The teams, also known as constructors, were Red Bull Racing, McLaren, Ferrari, Mercedes, Renault, Williams, Force India, Sauber, Toro Rosso, Lotus, HRT and Virgin. The Grand Prix was contested by twelve teams, each of two drivers. At over four hours (including a red flag period) the race set the record as the longest in Formula One history. In the World Constructors' Championship Red Bull extended their lead to 65 points from McLaren, with Ferrari a further 85 points behind. Webber remained in third, and Hamilton's retirement meant he slipped to fourth. 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. Williams driver Rubens Barrichello finished in 9th place, scoring his final F1 points. 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. Button was involved in another collision on lap 37, which led to Alonso's retirement and Button falling to last place. By lap 26, increasingly heavy rain led to the race's suspension, before it was restarted over two hours later.

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. The race began behind the safety car, and once it returned to the pits Vettel built a lead over Fernando Alonso.

Sebastian Vettel, who started from pole position, finished second in a Red Bull Racing with teammate Mark Webber finishing third.

McLaren driver Jenson Button won the 70-lap race starting from seventh position. It was the seventh race of the 2011 Formula One World Championship and the 48th Canadian Grand Prix. 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.
