2005 Canadian Grand Prix

The 2005 Canadian Grand Prix (officially the Formula 1 Grand Prix du Canada 2005) was a Formula One motor race held on 12 June 2005 at the Circuit Gilles Villeneuve in Montreal, Quebec, Canada. The 70-lap race was the eighth round of the 2005 Formula One season, the 43rd running of the Canadian Grand Prix, and the 37th running as a round of the World Championship. It set a ratings record and was the most watched F1 race in history with 51 million viewers. It was also the first of two consecutive North American rounds.

The race was won by McLaren driver Kimi Räikkönen, taking his third win from four races. The two Ferrari cars completed the podium, with Michael Schumacher in second place and Rubens Barrichello in third. Both Renaults failed to finish the race, but the team maintained their lead in the Constructors' Championship; their driver, Fernando Alonso also kept his lead in the Drivers' Championship, despite the gap between himself and nearest rival Räikkönen closing by ten points.

After the European Grand Prix, Fernando Alonso led the drivers' championship with 32 points ahead of Kimi Räikkönen and Jarno Trulli. In the constructors' championship, Renault led McLaren-Mercedes by 23 points and Toyota by 32 points.

Christian Klien returned to the Red Bull cockpit after being replaced by Vitantonio Liuzzi in the previous four races.

The bottom 6 teams in the 2004 Constructors' Championship were entitled to run a third car in free practice on Friday. These drivers drove on Friday but did not compete in qualifying or the race.

Jordan was banned from running a third car at this race because Franck Montagny had used six sets of tyres instead of four at the previous race. Scott Speed made his debut in practice on Friday. He became the first American driver to compete in a Formula One event since Michael Andretti's 1993 Italian Grand Prix.

After retiring on the last lap of the European Grand Prix, Kimi Räikkönen was the 11th driver on the track in qualifying, and he managed to line up 7th on the grid. Ferrari's Rubens Barrichello suffered a gearbox failure before the start of his qualifying lap, and was forced to abort his run. Jenson Button managed to take pole position, with Michael Schumacher second, and both Renault drivers on the second row.

Barrichello, who would have been last on the grid, decided to start the race from pitlane, putting extra fuel in his car. At race start, both Button and Schumacher got away slowly, and Giancarlo Fisichella and Fernando Alonso took off well to move into first and second by the first corner. The McLarens of Juan Pablo Montoya and Räikkönen were also able to pass Schumacher, moving into 4th and 5th behind Button. Further back in the field, BAR's Takuma Sato made a small mistake, but did not lose a large amount of time. On the second lap, Fisichella was able to widen the gap back to Alonso, while local driver Jacques Villeneuve was forced to pit for a new front wing, leaving him at the back of the field. As the race continued, the Renault's pulled further away from the pack, and Barrichello was constantly moving up the field, up to 15th position by the end of lap 8. Narain Karthikeyan had a spin after a mistake in turn 1, allowing Jordan teammate Tiago Monteiro past.
