In junior hockey in Sorel and Montreal, as well as in the American Hockey League when he first turned pro, Mondou was an offensive star. Buried behind the likes of Guy Lafleur, Steve Shutt and Jacques Lemaire, Mondou became more of an all-round player with the Habs. He injected youth and life into the Habs dynasty, as well as four seasons with at least 29 goals. But he was better known as a support player who could add offense. He was versatile in that he could play either center or wing with equal ease. He excelled as a penalty killer, and, because of his skating ability, was often called upon to shut down the other team's top lines.
Unfortunately for Mondou his career came to a scary end at the age of 29. An errant high stick belonging to Hartford's Ulf Samuelsson clipped Mondou in the left eye. The incident happened as Mondou was scoring the game winning goal in overtime. Sadly it would the last goal Mondou would ever score, as he was forced to retire because of the injury.
In 548 regular season games Pierre Mondou scored 194 goals, 262 assists and 456 points while totalling 179 penalty minutes. He added another 17 goals and 45 points in 69 playoff games.
Mondou later served as a long time scout for the Canadiens.
