Ferrari took the quickest lap in today's practice session, but only by a hair as much of the field showed a lot of promise heading into tomorrow's qualifying session.
On-track action at the Circuit Gilles Villeneuve in Montreal has ended for the drivers of Formula One, and the Ferrari of Fernando Alonso ended up on top.
After a soaking wet first practice session, drivers were able to bolt on dry weather tyres and put their cars to the test. With that, Spaniard Alonso topped the charts with a lap of 1:14.818.
"The only certainty is that we must ensure we make the right decisions, because today we saw how getting a clean lap depends a lot on the time you make the decision and what track conditions are like at that moment," said Alonso.

Hamilton commented: "Hopefully it will be dry for qualifying tomorrow and we can have a strong day."
Force India, who has had some success at the Canadian Grand Prix in the fast only had one driver in the top ten, as Adrian Sutil was a little over half a second off the pace to hold on to 8th overall by sessions end.
Qualifying is slated for tomorrow afternoon, and according to Weather Canada, there is a 40 per cent chance of rain.
