Mailloux was loaned to AHL Laval on Sunday.
Montreal announced that Mailloux will represent the Rocket at the AHL All-Star Classic in Palm Desert, California on Monday. The Canadiens visit the Sharks on Tuesday, so Mailloux will presumably link back up with the team then. The 21-year-old has provided a goal and two assists across five appearances with the big club in 2024-25.
