Hirohide Hamashima - Director of Bridgestone Motorsport Tyre Development: "Congratulations to Lewis Hamilton for winning a difficult race. Hamilton had good patience in trying conditions and he showed strong pace on both a wet and dry track.
"We gained data from running with all our weather range of tyres today and each tyre worked well when used in the correct conditions and we are very happy with performance. Of course, drivers were not always on the correct tyre in the changing conditions and this made for an exciting race.
"Because of the weather conditions the track surface never rubbered up enough for the new super soft compound to really be put through its paces, but this should happen in Montreal."
