In 1970–71, Red Wings general manager Sid Abel wanted to get rid of coach Ned Harkness and was overruled by team owner Bruce Norris. Once Harkness took over as general manager, he got rid of players he deemed a threat to him. On January 13, 1971, Mahovlich was traded to the Montreal Canadiens for Mickey Redmond, Guy Charron and Bill Collins. He was reunited with his brother, who had become a star player himself with the Canadiens. Mahovlich spent three-and-a-half seasons in Montreal, playing on the Stanley Cup-winning teams of 1971 and 1973. During the 1971–72 season, Mahovlich scored a career-high 96 points, which he nearly matched the following season with 93 points.
