The 2004-05 season was truly has been a tale of two seasons for Duchesne, who began with the anemic Victoriaville Tigres. He struggled mightily playing behind Josh Tordjman, and it became obvious that he needed a change of scenery. The Halifax Mooseheads took a chance on the netminder, the son of former NHLer Gaetan Duchesne, at the deadline, to provide insurance for San Jose Sharks prospect Jason Churchill, should he falter. Falter Churchill did, and Duchesne seized his opportunity. Duchesne tore off a remarkable streak of nearly 15 decisions without suffering a loss, and did not lose until the second round of the playoffs.
2005-06: Duchesne has struggled some while leading a much more inexperienced Halifax team. He enjoyed a strong first half of the season, going 17-14 with a 3.10 GAA and .900 save percentage. He went just 8-15 with a 4.03 GAA and .892 save percentage over the second half, however, his numbers suffering as the team’s overall level of play dropped.
2006-07: Duchesne was the last of the Flyers’ prospects to be eliminated from postseason play last season, when his Val-D’or Foreurs were swept in the QMJHL finals by the Lewiston MAINEiacs. The Silver Springs, MD native enjoyed a spectacular postseason run, but all of that was trivialized due to personal tragedy. His father, former NHL forward Gaetan Duchesne, passed away suddenly at the age of 44 on April 16, prior to the Foreurs’ semifinal series against the Cape Breton Screaming Eagles.
The 6’1, 210 lb. netminder began the 2006-07 campaign, his fourth in the QMJHL (third as a starter) with the Halifax Mooseheads. He was traded to Val-d’Or during the Christmas trade period, and finished the regular season ranked 10th in the circuit with a 3.33 GAA and eighth in save percentage with a .897 mark.
2007-08: Duchesne went 1-0-0 with the Philadelphia Phantoms (AHL) before being sent to the Dayton Bombers (ECHL). With Dayton, he went 13-13-0 with a 2.97 goals against average and a .903 save percentage.
2008-09: Assigned to new ECHL affiliate Mississippi.
