The Toronto native was chosen 56th overall by the Pittsburgh Penguins in the 1972 Amateur Draft after two strong years with the OHA's Peterborough Petes. He played nine games in the NHL during the 1972-73 season but saw most of his ice time in the AHL with the Hershey Bears.
Lalonde scored 27 points in 1973-74 playing on an efficient line with Bernie Lukowich and Wayne Bianchin. He saw less ice time to start the next season then was traded to the Washington Capitals for Lew Morrison. The hard-working forward played parts of five seasons with Caps when they were one of the worst outfits in league history. In 1976-77, Lalonde scored 12 goals and was only -20 while teamed with wingers Craig Patrick and Bill Collins. He played nearly two years in the minors then one season with the Salzburg club of Austria before retiring in 1981.
