Mercedes are now ahead of Ferrari and Red Bull Racing in both the Drivers' and Constructors' championships, but have faced a stiff challenge in all the races thus far. Williams is now bottom of the constructors standings with just four points, all scored by Stroll in Azerbaijan.
If the four times world champion wins again on Sunday he will equal Michael Schumacher's record of seven victories in Montreal.
Mercedes also typically struggle to extract the same level of performance from softer tyres than their rivals and have been more conservative in their approach with just five sets of Hypersoft and five Ultrasoft, compared to eight and three sets respectively for both Ferrari and Red Bull.
"It's one that I've always loved driving on".
Red Bull's Daniel Ricciardo in action during the race.
"It is a very different track to Monaco", he added. "It was waiting, waiting, waiting and eventually we got out". Sauber's Marcus Ericsson also had a spin that left him facing the wrong way on the track, but he straightened out and resumed.
"It is of course Lance's home race, and also where he scored his first Formula 1 points past year in his rookie season, so it holds good memories".
Droves of race fans and drivers will soon be Montreal-bound to enjoy Grand Prix weekend, but one of the most notable auto companies seems to be a little confused about which city they're actually heading to. This season he is the only driver to not have been beaten by his colleague in qualifying sessions.
The racing division of the famous Italian auto company, Ferrari, was ridiculed online Tuesday after it tweeted about this weekend's upcoming Formula One race in Montreal using an image of downtown Toronto.
"I can't wait to get to Canada as it is my favourite race of the year", commented Stroll, who was himself born in Montreal.
"Following Lewis's pit stop, we believed that we had the scenarios of both the safety vehicle and the virtual safety auto covered, so that Sebastian could not pit and come out ahead of Lewis on track".
