The Canadian GP included four safety car periods and one of the biggest crashes of Formula One in that era. The race started off with the second all-McLaren front row with Hamilton taking his first pole position followed by Alonso. Alonso made a mistake in turn 1, losing several places while Hamilton was opening a gap between himself and Nick Heidfeld. On lap 22 the first safety car period began after Adrian Sutil hit the concrete wall. The safety car went into the pits on lap 28 but before the lap could be completed Robert Kubica had a massive accident. He had lost his front wing after hitting Jarno Trulli. He then went wide and hit a bump on the grass that launched him into the air and into a violent impact with the retaining barrier at a peak deceleration of 75G. The safety car was once again deployed and went in on lap 35. Hamilton once again opened up a gap to second-placed Heidfeld until lap 50 when Christijan Albers left a lot of debris on the track after a crash forcing the deployment of the safety car. The race restarted on lap 55 and the safety car was deployed again on lap 56 after Vitantonio Liuzzi hit the so-called 'Wall of Champions'. The safety car period was extended after Jarno Trulli hit the tyre barrier at the exit of the pitlane after trying to catch up with the field. On the restart Hamilton led to the finish to claim his maiden win in his sixth race. The next race at Indianapolis saw Hamilton lead from the start until victory after a 300 km/h side by side battle with Alonso for the lead. Ferrari took their first 1–2 finish of the season in France with Kimi Räikkönen winning from polesitter, Felipe Massa.
