Going into the weekend, Mercedes-AMG's Lewis Hamilton leads the 2018 Drivers' Championship with 110 points.
The Mercedes of Valtteri Bottas will also start in the front row.
The Scuderia Ferrari driver secured the Italian team's first pole position around the Circuit Gilles Villeneuve since Michael Schumacher in 2001, with Vettel putting in an incredible lap time in an intense qualifying session.
Stroll and Hartley's coming together saw the safety auto deployed but that was the extent of the drama.

Red Bull, which starts on hyper-softs, will hope to mitigate that degradation in the opening stint, and on Friday appeared to be the only one of the top three teams capable of doing that successfully.
The Spaniard now turns his attentions to the Le Mans 24 Hours race with Toyota next weekend. "So I tried it all but I wasn't sure until the end if it was enough. I think we can do a good job". Even given the new engine Vettel had the pace of the field and managed his one-stop race untroubled to the flag.
