Ralf and Button get flying start

Ralf Schumacher and Jenson Button both made a clean start to the Canadian Grand Prix from their front row positions, but there was trouble for David Coulthard and Jarno Trulli.

The German Williams-BMW driver led Button in his BAR by 1.1 seconds after the first lap as the notorious first corner at the Circuit Gilles Villeneuve catered for just the one incident involving Coulthard.
