Racing Point haven’t scored points since both Perez and teammate Lance Stroll both got in the top ten in Baku in April.
Despite this poor run of form, the team still fifth in the constructors’ standings, but have four teams breathing down their necks, so points in Canada are badly needed.
Perez said: “We’ve had a tough couple of races in Spain and Monaco, but I feel more positive about our chances in Canada.
“I can see how much effort is going on behind the scenes to bring performance to the car and I believe we are moving in a good direction. Montreal is a very unique track all about straights and high-speed chicanes, which I think will suit our car.
“The Montreal circuit has always been good to me. I had a podium there in 2012 and I really love the event. It’s not just Canadian fans because I always meet lots of Mexicans who have come to watch the race. I always smile when I see a Mexican flag in the stands."
