Reigning Formula 1 champion Lewis Hamilton sent out a message to his Mercedes teammate Nico Rosberg by storming to the top of the timesheet in the first practice session of the Canadian Grand Prix on Friday.
The Brit sped around the track on super soft tyres to clock a time of 1:14.980, while Rosberg, who has a 24-point lead over Hamilton at the top of the driver rankings, was three tenths of a second slower.
Sebastian Vettel was third quickest in the field, while his Ferrari teammate Kimi Raikkonen was fifth, with Red Bull's Max Verstappen clocking the fourth-fastest time.
There were problems for Felipe Massa, though, as his Williams smashed into the barrier at Turn One, completely ruining the rear wing.
