Lewis Hamilton was promoted to first place at the Circuit Gilles Villeneuve — the British star claiming his fifth win from seven rounds — following Vettel’s five-second punishment for almost crashing into his Mercedes rival.
Backing their driver, Ferrari said they were “disappointed” by the steward’s decision and on Monday morning it was confirmed that they have appealed.
On lap 48, and with Hamilton crawling all over his Ferrari gearbox, Vettel lost control, sliding over the grass at the third bend before re-joining the track.
But Hamilton, who was forced to brake to avoid a collision with the recovering Ferrari driver, accused Vettel of dangerous driving.
Hamilton was jeered on the podium — the strong contingent of Ferrari supporters in North America unhappy with a penalty which denied Vettel his first win since last August’s Belgian Grand Prix and the Scuderia’s first of a disappointing campaign.
