After a tough time last time out in Monaco, the Silver Arrows bounced back on Friday in Montreal, topping opening practice and ending the day second and fourth fastest.
Lewis: It should be game on for the rest of the weekend
Lewis hit the ground running in first practice, edging Championship leader Sebastian Vettel by 0.198 seconds to go quickest of all in the morning. Kimi Raikkonen hit back in the afternoon, putting Ferrari fastest on Friday, with Lewis was just 0.215s back.
"It's been a pretty good first day for the tea," said Lewis. "The Ferraris are looking fast here and as the times show, it's super close at the top right now.
"I feel like we are still just a little bit behind the red cars at this early stage of the weekend, but we'll be pushing as hard as we can to close the gap ahead of qualifying on Saturday.
"After a tough weekend in Monaco, the main thing is that our car is already feeling a lot better around Montreal. It should be game on for the rest of the weekend."
Valtteri: It's the next two days that count
Valtteri clocked the third fastest time in the morning, 0.237s shy of Lewis' session-topping time but another two tenths clear of Raikkonen's Ferrari. Valtteri ended up fourth in a super-tight FP2, as 0.375s covered the top four positions.
"After Monaco it was really nice to start this weekend with a positive feeling from the car," said Valtteri. "I think that we are looking quite competitive here, but it's only practice.
"After practice two, it's clear we still have a bit more work to do with the UltraSoft tyre to get more laptime out of those. But the car felt good on the Soft tyres that I tried.
"We'll focus on finding that edge of extra performance from the UltraSoft and fine-tuning the set-up overnight. Otherwise I really enjoyed it and had good fun out there, but it's the next two days that count."
James: We had a trouble-free day
While the conditions weren't ideal out on track on Friday, Silver Arrows Technical Director James Allison is expecting another good battle for the top spots come crunch time on race day.
"We had a trouble-free day with both cars which allowed us to get through our planned practice programme," said James.
"As always on the first day in Canada, conditions were tricky owing to the low grip levels and the circuit seemed particularly dirty today. That factor, plus the number of cars on a short lap, made it difficult to put together consistent and meaningful running.
"Nevertheless, what we have seen so far suggests that we will have another ding-dong battle on our hands, like at the first six races - and it is very hard to predict who will come up with the goods on Sunday."
