Ferrari's Fernando Alonso set the early pace in Montreal on Friday morning, mixing it up with Michael Schumacher and Lewis Hamilton.Felipe Massa also joined the tussle, while late-starter Vettel only ventured out after half the session was already over.
And, unfortunately for the Red Bull driver, what time he had left was cut short when he locked up into the final corner and slammed his RB7 into the Wall of Champions.
With the session back underway after six minutes, it was Alonso and the two McLaren drivers fighting for the P1 slot before Merc GP's Rosberg put in a late charge to beat them all.
Rosberg finished up with a 1:15.591, 0.548s up on Alonso while Schumacher was third fastest.
Report: Blue skies and sunshine greeted the drivers at the start of Friday morning's practice for the Canadian GP with the track temperature already up to 27'C as Heikki Kovalainen led out the drivers for their installation laps. Problems for Jarno Trulli with as the Team Lotus driver hit a bird on his installation lap. Not a pretty sight on his front wing.
Toro Rosso tester Daniel Ricciardo got proceedings underway with a 1:26.560. His reign was short-lived as Fernando Alonso took the P1 slot with a 1:19.981 and Michael Schumacher slotted into second place. Schumacher went on to overhaul Alonso with a 1:18.821 while Lewis Hamilton claimed third place.
The McLaren driver continued lapping, taking first place by almost half a second ahead of Schumacher. Jaime Alguersuari put his Toro Rosso into third place with Nico Hulkenberg taking fourth ahead of Mark Webber and Nico Rosberg.
Alonso returned to the front with a 1:18.326 before being dropped by Rosberg and also by Webber, who was 0.029s off the P1 time. Hamilton improved to fourth. It was all-change, though, as Felipe Massa hit the front, the first driver into the 1:17s.
Sebastian Vettel finally hit the track for his first timed lap, taking 17th place. The reigning Champ continued lapping, improving to 10th place. Alguersuari was the latest to be caught out at Turn 8, however, it was Vettel who was well and truly caught out.
Out on the soft tyres, the reigning World Champ locked up his right front under braking for the chicane and hit, yip, the Wall of Champions! Vettel escaped unhurt from the accident but the same cannot be said of his car. His RB7 suffered serious damage to the front right.
The session was red flagged for six minutes with the drivers quickly out on track. Massa almost followed Vettel into a wall, although a different wall, the one just after the Turn 3/4 chicane. Paul di Resta almost binned it as well, forcing Trulli to take evasive action. Nick Heidfeld spun his Renault, although that's better than his team-mate Vitaly Petrov who had not even set a time with 20 minutes remaining.
Alonso took over at the front with two purple sector times. Hamilton ran off the track and Button climbed to third place behind the two Ferraris. Rosberg overhauled the Ferraris, a 1:16.002 for the Merc GP driver. Schumacher took third place, 0.983s behind his team-mate. Rosberg, meanwhile, reported to his team that he could feel something burning in the cockpit. That's never good.
Practice One ended with Rosberg in the P1 slot with a 1:15.591. Alonso and Schumacher were second and third ahead of Massa and the two McLarens.
