2009-10: Hudon played for the Saint-Eustache Vikings midget AAA team in Quebec. In 40 games he scored 23 goals with 24 assists and had 32 penalty minutes. He was selected by Chicoutimi in the first round (sixth overall) of the 2010 QMJHL Entry Draft.
2010-11: Hudon was named to the QMJHL All-Rookie team and received the Michel Bergeron Trophy as the Offensive Rookie of the Year in his first season with Chicoutimi. He also competed in two international tournaments – representing Quebec in the 2011 U17 World Hockey Challenge and skating for Canada at the 2011 U18 World Junior Championship. Hudon was the second-leading scorer for the Sagueneens with 23 goals and 37 assists and was plus-26 with 42 penalty minutes in 63 games. Chicoutimi finished fourth in the East Division and was swept by Drummondville in a first round playoff series. In four playoff games Hudon had 3 assists and was minus-four with 4 penalty minutes. At the WHC, he was second among all scorers with 5 goals and 6 assists in six games. Quebec advanced to the bronze medal game.

2011-12: Hudon again finished second to Guillaume Asselin in scoring in his second season with Chicoutimi and was a big part of the Sagueneens' strong playoff run. He scored 25 goals with 41 assists and was plus-28 with 50 penalty minutes in 59 games as the Sagueneens slipped to fifth in the East. In the playoffs, Chicoutimi defeated Acadie-Bathurst and Shawinigan in two tight series and were the only team to defeat Memorial Cup-bound Saint John in a playoff game; taking the Sea Dogs to overtime in the last three games. Hudon scored 6 goals with 5 assists and was plus-five with 16 penalty minutes in 18 playoff games. He was ranked 95th amongst North American skaters in Central Scouting's final rankings prior to the 2012 NHL Draft.
Hudon is mainly known for his offensive skills but can also play defensively as seen by his solid plus/minus differential over the last two years at the junior level. The talented winger is blessed with superior hockey sense, a great vision and quick hands which allow him to control the play in the offensive zone and create scoring opportunities for him and his line-mates. The 18-year-old has shown a maturity beyond his age by providing leadership, character and a strong work ethic for his Chicoutimi teammates. The smallish forward will need to add more muscle mass to withstand the physical play along the boards while working on his skating edge control and his four step acceleration.
Hudon will be returning for his third season in the QJMHL with the Chicoutimi Saguenéens and has a good possibility of playing for Team Canada at the 2013 World Junior Championship.
