Resident of Beaurepaire, Roy Pelletier opened in 1954 Roy’s Rexall Drugstore at 454 Beaconsfield Boulevard (now occupied by Galerie d’art Chase). In 1961, he was one of the businessmen to erect a Commercial Building at 438-448 Beaconsfield Boulevard.

Paul Pelletier, Roy’s father, formerly a welder, along with wife Mary Strathdee (died 1965) lived in the apartment above their son’s pharmacy at 450 Beaconsfield Blvd from 1953 to 1981. He was a fixture in Beaurepaire Village and would greet people as they entered the store. He would swap recipes with the ladies and swap fishing stories with the men shopping there and could often be heard playing his Hammond organ in the apartment upstairs.
In 1985, when the Dominion store closed at 485 Beaconsfield Boulevard across the street, Roy Pelletier moved his drugstore there under Pharmacie Jean Coutu banner.

His son David Pelletier is the Beaconsfield City Councillor for District 1 (2013- ).
