Lewis Hamilton had the measure of his rivals in Friday's first practice in Montreal as the McLaren driver set the pace despite using the slower tyres...
With dark threatening clouds overhead, the Lotus drivers got proceedings underway as Kimi Raikkonen posted a 1:20.347, which is almost immediately topped by his team-mate Romain Grosjean. The duo traded blows for several laps before Nico Rosberg put an end to their intra-team tussle.
Lewis Hamilton was the next to lead the way as the McLaren driver posted a 1:16.080 while Kamui Kobayashi and Felipe Massa slotted in behind him.
Hamilton's time seemed to be unbeatable as his rivals tried but just couldn't match it. Sebastian Vettel came the closest, 0.063 down before Practice One was red flagged.
With 38 minutes left on the clock, Heikki Kovalainen sideswiped the wall at Turn 9. The impact, which was on the right side of his Caterham, left a significant amount of debris on the track. The Finn, though, was unhurt.
The session restarted roughly ten minutes later with Rosberg the first into the 1:15s. But his reign was short-lived as Hamilton posted a 1:15.564.
A near miss for Bruno Senna who was almost collected by a Red Bull as the Williams driver just didn't have the pace through the corner as Vettel came storming by. The Brazilian was seen waving his fist with the stewards announcing they will investigate the incident after practice.
The final five minutes saw several drivers swap to the red-ringed super soft Pirelli tyres. However, even though the Red Bull duo made the move neither Sebastian Vettel nor Mark Webber were able to challenge Hamilton with Vettel slotting into second place, 0.118s down.
The session ended with Hamilton first ahead of Vettel, Rosberg and Alonso.
