A very mixed picture emerged from the first day of practice at the Circuit Gilles Villeneuve, where Kimi Raikkonen was in second place on the timesheets and Seb Vettel managed fifth best after losing some time in the garage and then being hampered by a red flag and traffic on his fast runs. The Canadian circuit is notorious for featuring strong track evolution as the weekend progresses, so it is not easy to predict what the future holds.

Sebastian Vettel: "We're not far off, although I am not entirely happy yet and there's still some work to do. In the end I didn't do many laps today and I think we were running a bit late. It is difficult to get to know all the answers, I think we need some more time to get everything together and then we'll see what happens. We tried various things, but there's still something we have to work on. I didn't get into the rhythm, but tried to go through as much of the programme as we could. In the end, we need more time to get a better picture of the situation. Hopefully, putting everything together can help us tomorrow. Now we'll stay focused on the work to do."

Kimi Raikkonen: "This track is not the easiest to get things where you want them. It's not straightforward and we expected that. It's very bumpy, not just with all the bumps, but also with the kerbs to ride over. The combination of low downforce and low grip can make it very difficult. As for the Hypersoft tyres, at least we have a better idea of how they work. They're good on one lap and then last quite a few more. We've been improving during the day and that proves that we're going in the right direction. For sure we have some work ahead of us, but I was a bit happier at the end of the session."
