Leblanc was selected by the Canadiens in the first round (No. 18) of the 2009 draft. In 50 games with Montreal, the right-shooting Quebec native has five goals and five assists. He spent much of this season with the Canadiens' American Hockey League affiliate in Hamilton, where he scored 10 goals and 18 points in 62 games.
"After three seasons with the Canadiens organization, we felt that moving forward the best option for Louis and our organization was to give him the opportunity to pursue his career with another team," Canadiens general manager Marc Bergevin said. "Throughout his entire stay with our organization, Louis showed great professionalism and a constant desire to improve. We thank him for his contribution and wish him success for the continuation of his career."
