He scored 22 goals with 26 assists in 41 games. L’Intrepide finished fourth in the CCM Division. Dunn scored 1 goal with 8 assists and had 2 penalty minutes in four playoff games.

Dunn played in three of four playoff games in the first round series with Rimouski; scoring 1 goal with 5 penalty minutes.
2012-13: Dunn provided both scoring and toughness for Val’d-Or in his second season. He was the Foreurs’ fourth-leading scorer with 25 goals and 27 assists in 53 games, missing most of January, and shared the top plus/minus for the Foreurs (+21) with Anthony Mantha. Dunn’s 98 penalty minutes were third-most on the team. Val-d’Or finished fourth in the West with 35 wins (the most since 2006-07) and reached the second round in the playoffs. Dunn had 3 assists and was -1 with 19 penalty minutes in 10 playoff games. In June, he was obtained by his hometown Gatineau Olympiques in a QMJHL draft day trade. Dunn was ranked 73rd amongst North American skaters in the Central Scouting final rankings and was selected by Ottawa in the fifth round (138th overall) in the 2013 NHL Draft.
2013-14: Dunn made his professional debut with Senators’ AHL affiliate Binghamton in an April 19th game against Norfolk following his junior season with Gatineau. He had no points nor penalties in his only AHL game. Obtained by Gatineau from Val-d’Or in a QMJHL trade in June 2013, he was the third-leading scorer for the Olympiques despite missing 18 games. Dunn scored 31 goals with 20 assists in 50 regular season games and was +10 with 156 penalty minutes. Gatineau finished fourth in the West Division and reached the second round in the playoffs. Dunn scored 3 goals with 6 assists and was +2 with 26 penalty minutes in nine playoff games.
2014-15: Dunn signed a three-year entry-level contract with Ottawa in August 2014 before returning to the QMJHL for a fourth season. He had a tumultuous season with the eventual QMJHL champion Rimouski Oceanic. Obtained by Rimouski from Gatineau in an off-season trade, Dunn skated in 46 games with the Oceanic, skating in his last game on March 4th before being released prior to the playoffs. Dunn scored 19 goals with 13 assists and was +13 with a team-leading 153 penalty minutes. The Oceanic finished first in the East Division and defeated second-place Quebec in the QMJHL finals to reach the Memorial Cup.
Dunn is a pest on the ice and makes his mark by getting under the skin of his opponents. He has only average size but that doesn't stop him from finishing his checks and battling hard against the wall. Perhaps even more frustrating for the opposition is that he has some scoring ability to go with his aggressive play. His scoring is often the product of his hard-nosed play rather than dynamic scoring talent but it doesn't matter how pretty a goal is on the scoreboard. His hard edge is the strength of his game but has also gotten him in trouble at times when he's crossed the line.
Dunn will skate for the Ottawa Senators entry in the Canadiens 2015 Rookie Tournament — looking to get his career back on track in 2015-16 after ending his junior season with Rimouski on a sour note. He is an antagonistic forward with some offensive skill and could be a Daniel Carcillo-type at the NHL level one day.
