Carlos Sainz in his Torro Rosso was the first vehicle to set a lap time but his time at the top of the time sheets was short lived when Kimi Raikkonen and Sebastian Vettel made up the top two on the supersoft compound tyre while everyone else ran around on the ultrasoft.
After the session, Hamilton was presented with one of Senna's old helmets, a gift from the late Brazilian's family for equalling his record. But it was Senna, Hamilton's favorite driver, who was the target. Speechless. I know that Ayrton was for many of you your favourite driver, and he was the same for me.
"Obviously, we'd like to be further forward, but I believe we maximized the potential today with a good, clean lap", Alonso said. He got in 25 laps.
"I remember coming home from school and putting on video tape of Ayrton so it is really odd to think that now I'm here and I have that many poles".
Hamilton was seventh in Monaco in the last race, his lowest finish this year and his second time missing the podium in six races.
Lewis Hamilton will start Sunday's Canadian Grand Prix on pole position ahead of championship leader Sebastian Vettel.
Vettel was the first vehicle out on track for Q3, but on his first timed lap he locked up going into the hairpin and compromised his run down the straight. Unfortunately for him, none of them were quick enough to beat Hamilton's mighty second attempt. "The guys did an fantastic job". "It's a problem that seems to have hit everybody, but not Ferrari".
Lewis' pole lap of 1:11.459s is the fastest ever lap of the Circuit Gilles Villeneuve.
Hamilton added that the quality of the competition from his fellow drivers was a key part of what drive him to success. "It's good to be heading back to Canada", he said. "Maybe in Monaco they were struggling a bit more in terms of pace but everywhere else, it would be unfair to say one was quicker than the other".
Wehrlein, whose auto was rolled over on its side in Monaco by Jenson Button, qualified in last place while McLaren's Stoffel Vandoorne and Williams's Canadian driver, Lance Stroll, also failed to impress.
But Hamilton wasn't finished, breaking his own record to strengthen his position at the top of the board.
Lewis Hamilton claims he has to produce near faultless performances to hold off Sebastian Vettel in what he calls his "most hard season".
"I'm not so happy with the last run I had", said Vettel. "It's a place I love and I really do love this track".
