The last couple of races haven't gone according to plan for Sauber, but the Hinwil squad are hoping for an upswing in their fortunes in Canada.
Having picked up 19 points between them in the first three races, Felipe Nasr and Marcus Ericsson found life a lot more difficult in the next three grands prix as they scored only two points.
The team had a particularly difficult weekend in Monaco as both drivers failed to make it into Q2, but there was some good news as Nasr battled his way to P9.
Head of track engineering Giampaolo Dall'Ara says their C34 should be better suited to Circuit Gilles Villeneuve.
"Although we managed to score two points at Monaco, the last two races have been rather difficult for the Sauber F1 team," he said. "Our main target for the Canadian grand prix is to turn this around.
"The nature of the Montreal circuit is remarkably different and we expect it to fit the C34 better: straight-line speed, braking and generally low-speed cornering performance dominate for lap time.
"Depending on the weather, at times rainy, the track allows to alter the aerodynamic configuration of the car trading off downforce for drag reduction. We will have again the soft and supersoft tyres. It will be important to place our drivers further up the grid, and from there target to score more points."
Ericsson, who will make his second visit to Montreal following his debut with Caterham last year, is also confident of a strong performance.
"Montreal is one of the tracks that should suit our car better mainly because of the long straights," he said. "As we do have a high top speed, it could be positive for us.
"Besides the engine power, braking stability as well as a good change of direction will be important. The many long straights also make overtaking easier on this track. Due to the track characteristics, I think our performance should be stronger in Montreal."
