Montreal:Michael Schumacher continued his domination of the Formula One season on Sunday when he won the Canadian Grand Prix for the third year in a row, and seventh time in the past eleven years. The Ferrari driver finished just ahead of his younger brother Ralf in his Williams-BMW with Rubens Barrichello, also of Ferrari, in third. It was the elder Schumacher's seventh victory in eight races this year and his 77th F1 win. Williams, Toyota disqualified Much later after the race however, Williams and Toyota were disqualified after technical checks on their cars' brake ducts. The disqualification meant that Ralf Schumacher lost his second place and BAR's Briton Jenson Button moved to third -- his sixth podium in the last seven races. Italy's Giancarlo Fisichella for Sauber moved up to fourth place, with McLaren's Kimi Raikkonen and David Coulthard fifth and sixth in a windfall for the struggling team who had scored just five points before Sunday. Start off Ralf Schumacher was the brother who started on pole for Sunday's race in Montreal. Michael was a season-worse sixth place on the grid. But that was to be of little consequence by the end of the race. The Ferrari driver and six-time world champion used a two pit-stop strategy to perfection that put him in the lead for good on the 48th of the 70 laps at Circuit Gilles Villeneuve. The race did not begin well however with Jarno Trulli's Renault slowing on the start. He slipped to the back of the 20-car field and pulled off course with a broken driveshaft. The same problem took out teammate Fernando Alonso later in the race. Also on the start, McLaren's David Coulthard slid sideways and Jaguar's Mark Webber and Sauber's Felipe Massa came together. All were able to continue except Trulli, who had qualified third. Williams say they will not appeal. Brothers duel Both Schumachers were well clear of all the trouble and roared ahead, swapping the lead several times during their pit stops. It was on Ralf's third stop however that Michael in his Ferrari took the lead for good. The elder Schumacher built his advantage to nearly ten seconds at one stage. He was forced to slow in the remaining laps as he attempted to conserve his brakes but still took the checkered flag around ten car lengths ahead of his younger brother. "It just worked out fantastic. The pit stop was great. Engineers, mechanics, everybody just done a superbly job. Car preparation was fantastic although I have to say my team-mate Rubens, he pushed me very hard and I think he got the better deal in his car and his drive this weekend. He was very strong in the second stint in particular but we managed it, we managed it another time and it is fabulous," said Michael. "It was clearly better than expected but still disappointing if you start on pole, and you finish second is not where you wish to be but still from where we came and the problems we had so far, to split up two Ferraris is rather good success," said Ralf.
