The Grove-based outfit’s drivers both failed to qualify in the top 10 for the Monaco Grand Prix and only Felipe Massa made it to the chequered flag, finishing in seventh place.
Bottas was on course to score points when a power-unit problem forced him stop his smoking car at the Mirabeau hairpin and retire on lap 55, ending his run of consecutive top 10 results.
Red Bull had the second fastest car last time out, but the Finn is expecting Williams to be stronger at the Circuit Gilles Villeneuve this weekend.
“I think we can still fight [Red Bull],” Bottas told Autosport. “It’s not easy – they are really improving, [but] Monaco was probably their strongest place of the season.
“On paper, Monaco was one of the more difficult tracks for us. We just need to keep working on the updates. In theory Canada should be one of the good ones for us [with] long straights.
“We know in Canada it can be cold and sometimes people struggle with getting front tyres up to temperature, so we really need to take some action. We know the issue, so we are now looking to solve it.”
Earlier in the week, Rob Smedley – head of vehicle performance – said Williams should be more competitive at the Montreal track due to the straight-line speed of the FW36: “Our car is aerodynamically efficient which is vital on the long straights in Canada so we feel we are in good shape.”
