While with the Montreal Junior Canadiens in 1943-44, Gerry Plamondon led the QJHL in goals scored, netting 21 markers in 15 games. His road to the top looked promising.
He took his first major step by turning pro with the Pittsburgh Hornets of the AHL in 1944-45. His stay with the club lasted only four games, however, before he joined the Valleyfield Braves of the QSHL. There, Plamondon looked like a serious prospect with a hot stick. By year two with the club, he led the league in goals scored, potting 40 in 39 games.
But the great obstacle in Plamondon's career became quite apparent when he picked up a few games here and there for the Montreal Canadiens. Although a deft scorer in the minors, he was unable to conjure the same success in the majors. Between 1945 and 1950, he appeared in a total of 86 regular season and playoff contests while sporting a Habs' sweater. Between stints at the Forum, he continued to carry a hot scoring hand with the Montreal Royals of the QSHL.
In 1950-51, Plamondon played one final match with the Habs and then returned to the minors for good, skating for a variety of clubs including the Matane Red Rockets, Chicoutimi Sagueneens, Cornwall Chevies, and Pembroke Lumber Kings where he retired at the close of the 1957-58 campaign.
