"Yesterday we were in trouble in practice as I wasn't really happy with the vehicle because we had some problems and I couldn't get the rhythm".
Hamilton is concerned about the fact that Mercedes are the only engine manufacturer who have not brought an upgrade to Canada, where engine power is more important in overall laptime than at many other tracks.
"There was no chance to go slalom around them". I think the highest minimum speed is 140kph, so we knew coming here it would be hard and the characteristics would be a problem.
Charles Leclerc also impressed in P13 for Sauber, the fourth consecutive race the Monegasque has made it two Q2 and he out-paced both McLaren's with Fernando Alonso 14th just ahead of teammate Stoffel Vandoorne.
"It's never happened to me", he told reporters afterward. "There was some electrical stuff going on that hindered us this morning and then this afternoon, so not the best day, but we're OK. It was a bit surprising, there was no way for me to carry on".
"Today I switched on".
"Yesterday, we were in a bit of trouble", Vettel said.
"It was a special feeling pulling out of pit lane - I had a big smile on my face", said Latifi.
Formula One's youngest race victor arrived in Montreal under attack from all corners, after an incident-filled start to the season that has seen the 20-year-old reach the podium once in six races while Ricciardo has recorded a pair of wins. "It has brought me to where I am right now and after the race is not the right time to talk".
However, he wanted to get a feel for the softest tyre before the decisive Q3 session, but had to abandon the lap when he caught a train of four slow cars on the long straight before the final chicane.
Lewis Hamilton slipped up in qualifying. "We improved during the day, but it was not easy and we have had easier days than this!"
It is a welcome return to form for Verstappen, who ahead of the weekend looked agitated in Thursday's press conference, half-joking that he "might headbutt" the next person to ask him about the series of crashes and incidents which have overshadowed his first six races.
"No, we didn't. It was a very smooth session, to be honest".
A year ago he dominated the grand prix, starting from pole and leading every lap on his way to the win, while behind him there was plenty of drama.
"I think we've learned a thing or two from Monaco about the HyperSofts, so hopefully we can make them work".
A rare day in Formula One saw two Canadians on track at once - Williams driverLance Stroll of Montreal and Force India reserve driver Nicholas Latifi of Toronto, who ran only in the first of two 90-minute practice sessions.
