The 2004 Canadian Grand Prix was a Formula One motor race held on 13 June 2004 at the Circuit Gilles Villeneuve. It was Race 8 of 18 in the 2004 FIA Formula One World Championship.
It was won by Michael Schumacher, with teammate Rubens Barrichello second, making for a 1-2 finish for Scuderia Ferrari.
In the post race inspections, Williams and Toyota were excluded from the race due to illegal brake ducts.
This would be the last time that Scuderia Ferrari won in Canada until 2018 and the last time that more than two cars were disqualified from a race until the 2025 Chinese Grand Prix.
