I think we need a little bit of time to understand the full picture but as I said I'm not yet happy with the auto.
"Some of the marshals were already celebrating", he said.
Valtteri Bottas of Mercedes will start beside Vettel on the front row. Max Verstappen was third and the other Red Bull vehicle, driven by Daniel Ricciardo, was fourth. He has a 14-point lead over Vettel and a 38-point edge on Ricciardo.
Hamilton endured engine troubles in Montreal, eventually finishing fifth to lose the championship lead.
"It's 50 for me but after a long stretch that Ferrari didn't win here, I saw the people around and they were super happy".
The victory, Vettel's third of the 2018 Formula 1 season, is his second triumph in Canada, and sees him retake the lead of the driver's world championship over Mercedes' Lewis Hamilton, who finished fourth. Today I think we had a couple of small lock ups, but as you continue to push the setup there are areas that can be affected.
His engine was six races old but Hamilton would have expected better.
"First of all, we could not use our new engine, which is a part of it", he said.
There was joy for both Force India drivers, though, as they both made it to Q3 for the second race running, so Esteban Ocon and Sergio Perez will start either side of ninth-placed Carlos Sainz.
The only other retirement besides Stroll and Hartley was McLaren's Fernando Alonso who reported a loss of power due to an exhaust problem and was forced to garage his auto - a disappointing end to the Spaniard's 300th race.
Although the race ended in slightly freaky circumstances, it began with huge drama after Lance Stroll and Brendon Hartley crashed on lap one.
They should have new pieces for the next race June 24 in Le Castellet in France. Both cars were badly damaged but the drivers escaped uninjured. From the start, all of a sudden I was down on power and my engine was saying it was over-temperature and I couldn't get the temperatures down.
It was also a short day for Stroll, a Montreal native who locked up with Hartley heading into Turn 5 on the first lap.
The likely reason is, at the first race the pink-striped Pirelli was used two weeks ago in Monaco, Red Bull was the only team to really extract a good race pace from it without suffering from too much graining or degradation.
Hamilton suffered with a power unit issue in the opening laps and was forced into an early stop where his team resolved the problem by removing some cooling vents.
It was the 300th F1 race for two-time champion Fernando Alonso of McLaren, good for fourth all-time.
