Valtteri Bottas similarly changed compound 20 laps later than teammate Lewis Hamilton and looked like possibly mounting a charge for the win in the final 10 laps, but a mistake trying to lap backmarkers ended any hopes of catching the German.
Hamilton, who had engine problems in the race, said: "It could have been a lot worse".
This left Vettel and Bottas out in front, 24 seconds ahead of Verstappen, but still running on their original ultra-softs. "I dedicate it to the team and to the Canadian (Ferrari) fans".
Although the race ended in slightly weird circumstances, it began with huge drama after Lance Stroll and Brendon Hartley crashed on lap one. "How can I be better?' I am going to keep doing that".
"I was just anxious, I told them on the last lap, so people don't jump on the track, waving flags and celebrating, because we are still going at full pace". I think they peaked a bit early, but majority are men so it might happen. With a new engine upgrade fitted to Vettel's vehicle this weekend, Ferrari was expected to be one of the favourites in Canada but Vettel was not happy with his performance after he was restricted to just 17 laps in second practice due to auto issues at the start of the session. I don't think anyone wants to be cheated of that. "The celebrity was not to blame", FIA race director Charlie Whiting said. Although the result was not affected, Daniel Ricciardo's fastest lap, which the Australian set at the death, did not count and was instead awarded to his Red Bull team-mate Verstappen.
Mercedes came to Montreal intending to introduce a new upgraded engine, but chose to postpone it due to reliability concerns while both Ferrari and Red Bull raced with theirs. "Ferrari have been doing the better job, particularly this month and their whole package has just been a little bit ahead of us".
"Their auto is fantastic and the engine, too".
"We need to review procedures and make sure we have a very simple procedure for every circuit", added Whiting. The two ran side-by-side on the run up to the second chicane, but Stroll broke loose and, upon correcting his FW41 chassis, drifted right into Hartley.
