The son of former NHL winger Claude Larose, Guy was a diminutive centre who played parts of six seasons with four different organizations. His strength was scoring goals and standing his ground in front of the net.
Born in Hull, Quebec, Larose played junior with the Guelph Platers and Ottawa 67's. He was claimed 224th overall by the Buffalo Sabres at the 1985 Entry Draft but never came to terms with the club. He signed as a free agent with the Winnipeg Jets and became a scoring star with the Moncton Hawks of the AHL.
Larose played only ten games in Winnipeg before he was traded to the New York Rangers where he was strictly used as a farmhand. In December 1991 he was dealt to the Toronto Maple Leafs where he was a popular sparkplug during the club's improvement in the second half of the schedule. Larose was only a part-time NHLer after this with brief stops in Calgary and Boston. He was a regular in the AHL and IHL then spent the 1997-98 with the ECR Revier Lowen club of Germany. Larose returned to North America and suited up with the Chicago Wolves of the "I".
