Friday 6 June at 22:23 : Montreal claimed its first victims as the second 90 minutes of unofficial free practice played out on a dry Friday afternoon.

Robert Kubica scraped gently along the same piece of concrete and survived to be second quickest for the second time on Friday, but Timo Glock had to abandon his bent Toyota when he too made contact with a Circuit Gilles Villeneuve wall.

Marshals struggled to pull Felipe Massa's failed F2008 behind the protective fencing after his Ferrari ground to a halt with an apparent technical problem.

Fernando Alonso had to walk back to the pits when his R28 would not budge following his last of a couple of spins.

Renault teammate Nelson Piquet also had a bad session; dead last, after placing seventeenth in the morning, and then stuck at the pitlane entrance with smoking wheels following a problem in the final chicane.

Honda's Jenson Button will also want to forget his Friday at Montreal; twentieth and slowest in the damp morning, improving to just nineteenth on the dry afternoon tarmac, more than two seconds from the leading pace.

Championship leader and this event's 2007 winner Lewis Hamilton topped the final session and the day, delivering not one but two late laps good enough for P1.
