Putting Ferrari on pole in Montreal for the first time since 2001 with a track record time, Vettel had powered into the lead and was never challenged as he charged home seven seconds clear of Mercedes's Valtteri Bottas.
Celebrities are often given the honour of waving the chequered flag at motor races, which has and have occasionally resulted in unintended flubs.
Winnie Harlow posted on her Instagram account: "WHEN THEY TELL YOU TO WAVE THE FLAG A LAP TOO EARLY!" He had lost two seconds and Vettel, turning the screw, responded with a fastest lap before cruising to a crushing victory.
"We were coming to Montreal expecting our vehicle to be really strong and we're leaving Montreal seeing we haven't been where we thought we should be".
"I'm just so happy that I finished as from the start I was down on power and my engine was saying that it was over temperature and I couldn't get them down", he said.
"We came to Montreal expecting to perform strongly and today's result is a further lesson to us that the historic patterns of performance between the teams are not holding true this year", Wolff warned.
"I am still here to win, I still believe we can win", Hamilton said.
As such Hamilton's lead in the standings became a one-point deficit. "We'd look back in ten races time and say that we actually had a fifth, it wasn't an eighth, it wasn't a DNF, I think I will be grateful for it". "This is a track where we should have maximised points - it is not about damage limitation for us".More news: Legislation would legalize marijuana, expand medical pot in New Jersey

A sideways moment from Stroll pushed Hartley into the wall - and the Toro Rosso rode up the TecPro barriers in spectacular fashion.
The Toro Rosso was launched into the air, wrecking both cars. "There's a long way to go in the season so I am not bothered about the title now, but it's a good side effect for me".
Speaking about the incident, Stroll said: "I was side-by-side with Brendon going into Turn 5, the auto got loose on me and I corrected it, but there was not much room for both of us".
"I was just anxious, I told them also on the last lap, then people don't jump on the track, waving flags and celebrating, because we're still going at full pace". Hartley went to hospital for precautionary tests but the team said he was OK.
The Silver Arrows' struggles on the compound come after they did very little running on the tyre when it first appeared in the end of season test in Abu Dhabi.
A "visorcam" view from Pierre Gasly's auto in Monaco caused a bit of a stir on social media as it offered a new view of a vehicle in action - and in Canada it was Romain Grosjean's turn. I think: 'How can I better them?
"I'm sure the next couple of days it will get more and more painful because ultimately it was a poor weekend, but it could be a lot worse".
