# 1986 Canadian Grand Prix

The 1986 Canadian Grand Prix was a Formula One motor race held at Circuit Gilles Villeneuve, Montreal on 15 June 1986. It was the sixth race of the 1986 Formula One World Championship.
The 69-lap race was won from pole position by Briton Nigel Mansell, driving a Williams-Honda. Frenchman Alain Prost finished second in a McLaren-TAG, with Mansell's Brazilian teammate Nelson Piquet third. Prost took the lead of the Drivers' Championship by two points from Mansell and another Brazilian, Ayrton Senna, who finished fifth in his Lotus-Renault.
This would prove to be the final Canadian Grand Prix held on the circuit in its original configuration with the pits and start/finish straight coming out of the Epingle de Casino Hairpin. After a sponsorship dispute saw the race not held in 1987, a new pit complex was built at the other end of the circuit just before the Epingle de L'ile Hairpin with the circuit also being reprofiled to accommodate a new start/finish straight that would open in time for the 1988 race. The changes to the circuit would result in one less corner (down from 19 to 18), but also added an extra 20 metres of track.
