# 1984 Canadian Grand Prix

The 1984 Canadian Grand Prix was a Formula One motor race held at Circuit Gilles Villeneuve, Montreal on 17 June 1984. It was the seventh race of the 1984 Formula One World Championship.
The 70-lap race was won by Brazilian Nelson Piquet, driving a Brabham-BMW. Piquet took pole position, led all 70 laps and set the fastest race lap, finishing 2.6 seconds ahead of Austrian Niki Lauda in the McLaren-TAG. Lauda's French teammate, Alain Prost, finished third.
The top six was completed by Elio de Angelis in the Lotus-Renault, René Arnoux in the Ferrari, and Nigel Mansell in the other Lotus-Renault.
After the race, Piquet climbed out of his car and collapsed on the ground, due to a badly burned right foot caused by the extreme heat from his Brabham's new nose-mounted oil cooler which had actually burned a hole in his driving boot. In the next race at Detroit, he had a special tray of ice for easing the blisters on his foot.
