2009-10: Jaedon Descheneau played for the Leduc Oil Kings bantam AAA team in Alberta. He was selected by Kootenay in the third round (62nd overall) of the 2010 WHL Bantam Draft.
2010-11: Descheneau averaged a point-per-game skating for the Leduc Oil Kings midget AAA team and competed for Team Alberta in the 2010 U16 Canada Winter Games. He scored 15 goals with 20 assists and 40 penalty minutes in 31 regular season games and scored 7 goals with 10 assists and 2 penalty minutes in 17 playoff games for the Oil Kings. Descheneau scored 2 goals with 2 assists and had 22 penalty minutes in five games as Team Alberta captured a bronze medal.
2011-12: Descheneau played in 54 of 72 regular season games for Kootenay in his first WHL season and represented Canada Pacific in the 2012 U17 World Hockey Challenge. He scored 3 goals with 11 assists and was -7 with 24 penalty minutes as the Ice finished fourth in the Central Division.

2012-13: Descheneau was the second-leading scorer for Kootenay in his second season with the Ice behind 2014 draft-eligible center Sam Reinhart. He scored 30 goals with 48 assists and was plus-9 with 22 penalty minutes in 69 regular season games. Kootenay finished fifth in the Central Division and lost to Edmonton in a first round playoff series. Descheneau had 1 assist and was minus-6 with 2 penalty minutes in five playoff games.
2015-16: Descheneau returned to Kootenay for an overage season — skating in two games with the Ice before suffering a shoulder injury in October that required season-ending surgery. He had 1 assist and was -1 with five penalty minutes in two games with the Ice.
Descheneau is an undersized sniper who put up big numbers in junior hockey skating with forwards like Sam Reinhart (BUF), Luke Philp and Tim Bozon (MON) in Kootenay. A bit of a late bloomer, he will be hindered by his size at the pro level but if he can add strength and develop his physical game he could be an interesting player to follow.
Descheneau missed all but two games in 2015-16, suffering a shoulder injury while skating for the Kootenay Ice as a 20-year-old. Drafted in 2014 in his second year of eligibility after putting up big numbers with the Ice, has yet to sign an entry-level contract and his professional future is uncertain at this point. Descheneau would be an unrestricted free agent if not signed to an entry-level deal by the Blues. His scoring ability and collection of offensive skills is intriguing but his lack of stature will be an obstacle in pro hockey.
