MONTREAL, Canada - McLaren's Lewis Hamilton returned to the scene of his first Formula 1 victory and set the quickest laps in both Canadian Grand Prix practice sessions. The 2008 world champion, a winner in Montreal in 2007 and 2010 but strangely without a triumph in this most unpredictable of seasons, was fastest in both sessions at an overcast Circuit Gilles Villeneuve. Hamilton set a best time of one minute 15.564 seconds in the morning and improved on that slightly with a 1min15.259s in the second session that concluded just before torrential rain and thunder swept across the city. BEATING FERRARIHamilton is a strong favourite to become the seventh different winner in seven races on June 10 and also has his eyes on McLaren's 150th pole. He said he could have gone faster: "I was out there pushing for quite some time on the option tyre, it was very difficult to put all sectors together. Sometimes I went a little bit quicker in one sector and then lost it in the second. "I think qualifying looks like it could be very close...you've got the Ferraris who are very quick as well and their tyre degradation seems to be better. So I'm keeping an eye out for them," he said. Hamilton was followed by the two Ferraris in the second session, Fernando Alonso lapping 0.054 off Hamilton's pace and team mate Felipe Massa third best and 0.151 slower. Red Bull's double world champion Sebastian Vettel, who was second fastest to Hamilton in the morning was fourth in the afternoon. Vettel’s team mate Mark Webber, winner in Monaco for Red Bull, lapped fifth fastest in the morning but was well back in 12th in the second. DECENT CHANCE McLaren's Jenson Button, the 2011 winner after coming from the back of the field at the restart to pass Vettel on the final lap, completed only 12 laps due to an oil leak and was 10th on the timesheets. He was able to improve on that effort later in the day with the ninth best time. Team principal Martin Whitmarsh said: "Jenson can drive brilliantly here as we saw last year and we've just got to give him a decent chance to do that." Both sessions were delayed by crashes. William’s Bruno Senna brought out the red flag in the afternoon session when he lost control of his car and slammed heavily into the 'Wall of Champions,' a notorious part of the circuit coming out a chicane entering the home straight that has claimed some of F1’s best drivers. Senna said: "I just pushed a bit too hard in the chicane. This is the Wall of Champions for a good reason, everybody seems to have anissue with that wall. "There's a lot of damage to the car but these guys (the mechanics) are going to get it sorted out and we are going to be back on track tomorrow," he said. Williams have brought a revised rear wing to Canada and Senna calmed fears that he might have to use an old type by saying he would have a spare one of the new specification. The morning session was red-flagged for 13 minutes when Heikki Kovalainen hit the wall and wrecked his Caterham, spreading debris across the track. Kovalainen said: "I was carrying a bit too much speed into that corner. I thought I'd got away with it but the rear end snapped away and that was it."
