Hamelin put up decent results through the 2012 season despite several nagging injuries and carried that success into the World Championships. There he won a silver medal in the 500 m trailing teammate Jean who won the gold. He went on to win the bronze in the 1,000 m after being pushed by a Chinese skater. Hamelin was injured in the fall and did not compete in the men's relay final, but still won gold for his earlier participation in the semi's.
