Hamilton was unusually out of sorts on a track where he has excelled so many times and a series of mistakes left him struggling to keep up with his rivals. We don't know what the other cars are doing, so we can not tell our driver "go right, go left". After leading all three practice sessions, Max Verstappen will start third in his Red Bull, alongside Hamilton.
"There are massive bumps into Turn 10".
"That situation was a bit unlucky - we were all bunched up". So constantly today going into that corner I was struggling to get the auto stopped, be it front locking or rear locking, so it was quite messy.
"I don't think the hypersoft is a good race tyre, so I'm a bit surprised that both of the Red Bulls chose that - but I guess they have their reasons".
When it comes to the twisty stuff, 11 of the 14 corners are taken below 100 miles per hour, which makes it particularly hard on the brakes and tires when the cars are coming from the high-speed straights.
Hamilton will start from behind the front-row in Montreal for the first time in seven years. "And I think if I get a few more, I'll head-butt someone". Toro Rosso were a match for Haas on the long runs on Friday, and Hartley himself pulled out his best qualifying performance since Bahrain to leave himself in striking distance of the points.
Ricciardo will be looking at those updates and also Red Bull's decision before signing a new deal. Ferrari's Sebastian Vettel is second with 96 points and Red Bull Racing's Daniel Ricciardo is third with 72 points.
Lewis Hamilton slipped up in qualifying.
‘First Man’ trailer: Watch Ryan Gosling as Neil Armstrong in biopic
Does the poster remind you of one for Mission: Impossible as it does me? The film lands in theaters on October 12. First Man also stars Corey Stoll as Buzz Aldrin, Pablo Schreiber , Kyle Chandler , and Jason Clarke .
Bottas said: "It was a good day here in Montreal even though it may not look that strong on the time sheets for us".
"We extracted the best we could out of qualifying".
"But it was a combination of things".
"It's hard to judge our single lap pace from today as we haven't run the HyperSoft and some of our closest competition looked to have had less than flawless sessions. You can't get them all and I'll try to recover from it tomorrow".
"I wanted to get a feel [for the hypersoft] and see where we end up", he said after the session.
Sebastian Vettel was pretty happy with his effort to take pole in Montreal - a lap record at Circuit Gilles Villeneuve.
However, Wolff said: "The fact is this is a championship that is going to be won and lost with the tiniest of margins".
"To compensate for this lack of low-speed grip we have to carry more wing which means more drag". We started to drive on the hyper today but was that the decisive factor?
Mercedes found a "quality issue" with their upgraded engine, believed to be a tolerance that would have made the engine unlikely to last the seven races engines need to run this season.
