Saturday free practice took place in continuing wet weather conditions in Montreal, with the Bridgestone runners demonstrating a clear advantage over their rivals.  Giancarlo Fisichella and Ralph Firman completed their programmes and were fairly satisfied with the pace of their EJ13s.

Gary Anderson said, "All went according to plan this morning, although it's difficult because there are so many different weather conditions as it rains harder or starts to dry, so in a sense we are playing catch-up all the time.  We tried various downforce settings, tyres, fuel levels and set-up configurations and we are reasonably competitive for where we want to be. Now we need to make the right decision for qualifying and tomorrow's race."
