Like Mercedes, both Red Bull and Ferrari are expected to use new engines, but Red Bull technical boss Adrian Newey downplayed expectations, notably because Monaco victor Daniel Ricciardo faces grid penalties for other technical power-unit changes.
However, a "quality issue" forced the team to abandon its debut until the French Grand Prix later this month, despite this, Bottas believes it won't hinder Mercedes' performance. Naturally it's degraded, you lose horsepower over races.
Montreal is the seventh of 21 rounds this season and the circuit's long straights and its power-sensitive nature means it is often a target for engine upgrades.
The Mercedes driver is the most successful driver of the current generation around the Circuit Gilles Villeneuve with six wins to his name, just one shy of the record held by Michael Schumacher.
Scorching the Circuit Gilles Villeneuve with the fastest times of the day will have that effect on a driver.
The Scuderia could also face a reduced threat from Red Bull as their vehicle is likely to be less suited on the long straights, though will be strong in the many heavy braking zones.
"It's a great track and a real test for the driver and the vehicle". "There's 21 circuits and it's impossible to be ideal on every single one".
"I've always enjoyed racing in Montreal".
"I've never driven the circuit in Montreal so I'm looking forward to driving there", said the Russian.
The new DRS zone for the Canadian Grand Prix will be between turn 7 and 8 and F1 executives hope that it will liven up the racing action. It will be tough to repeat his ninth place finish with the Williams team struggling to get the auto up to pace this season.
The race takes place Sunday in Montreal.
"It is a unique track, the walls are close, there's not a lot of room for error", said Stroll. "Those are the points we have now and we have to deal with it as a team".
