The GP2 star will also be in action in Austin later in the season.
"FP1 in Montreal will be my first drive of the year in the 2014 F1 car," said Rossi. "But after the amount of laps I’ve done in the sim with CT05 I’m already pretty familiar with how it’ll be inside the cockpit.
"Obviously it’s not quite the same as actually being out on track, but I have a lot of F1 mileage under my belt with the various FP1s and test days I’ve completed and having driven in FP1 in Canada last year I know I can go straight to work and help the team complete its plan for the session.
"The chances for young drivers like me to be in current-season cars on track are very limited, and obviously every lap counts over a race weekend but the fact the team sees that I can add value from the work I do in the car, and they can keep helping me to learn, shows great support and how committed they are to developing young talent. Now I’m focused on Friday morning.
"The weather should hopefully be dry so if that stays true we should have a full session run and be out as the green lights come on – if it rains then so be it, I’ll still be focused 100% on the job the team asks me to do."
The first session on Friday in the slowest car in the field will prove that if he ever wants a career driving a street sweeper, he'll be a shoe-in. As the track is dusty and not rubbered in, it's the primary session for the cars to clean the track. Rossi is very talented, but we are afraid his reputation will be forever tarnished driving for a backmarker as a track dust remover.
