Going into the weekend, Mercedes-AMG's Lewis Hamilton leads the 2018 Drivers' Championship with 110 points.
The timing of Vettel's win could not have been better, coming on the 40th anniversary of the late Gilles Villeneuve's victory for the Italian team in 1978 at his home Grand Prix.

Renault's Nico Hulkenberg took seventh place ahead of Force India's Esteban Ocon. "We didn't apply the pressure this weekend, but I'm really going to make sure I come back strong in the next race".
