2009-10: Loic Leduc appeared in two midget major games – seeing limited ice time for Cheateauguay Patriotes – and played the bulk of the season for Patriotes in Midget Espoir in Beauharnois. He was selected by Cape Breton in the second round (23rd overall) of the 2010 QMJHL Entry Draft.
2010-11: Leduc skated in 36 games for Cape Breton in his first QMJHL season. He scored 1 goal with 3 assists and was minus-14 with 27 penalty minutes. The Screaming Eagles reached the playoffs despite finishing last in the Maritimes Division and winning just 18 games. Leduc skated in 2 of 4 games in Cape Breton’s first round series with eventual champion Saint John and was minus-two with no points or penalty minutes.
2011-12: Leduc played in 65 of 68 games for Cape Breton in his second season. He was minus-3 with 2 goals and 8 assists and was third on the Screaming Eagles with 99 penalty minutes. Cape Breton finished fifth in the six-team Maritimes Division and once again ran into Memorial Cup-bound Saint John in the first round. In four playoff games Leduc was minus-nine with 1 assist and 4 penalty minutes. Leduc was ranked 209th amongst North American skaters in Central Scouting’s final rankings and was selected by the Islanders in the fourth round (103rd overall) of the 2012 NHL Draft.
2012-13: Leduc played in 38 games for Cape Breton in his third QMJHL season; suffering a season-ending “lower body” injury at the end of December. Playing on a Screaming Eagles team that had the league’s worst record, he had 2 assists and was minus-30 with 50 penalty minutes.
2013-14: Leduc attended training camp with the Islanders before returning to Cape Breton for his fourth QMJHL season and was acquired by Rimouski in exchange for a 2014 second round draft pick at the end of December. In 37 games with Cape Breton he scored 3 goals with 5 assists and was plus-6 with 58 penalty minutes. Leduc skated in 26 regular season games for Rimouski and scored 3 goals with 4 assists; finishing plus-7 with 44 penalty minutes. The Oceanic finished second in the East Division and reached the second round in the playoffs; losing 8-7 in overtime to Blainville-Boisbriand in the decisive seventh game of their series. Leduc had 2 assists and was plus-9 with 27 penalty minutes in 11 playoff games. He signed a three-year entry-level contract with the Islanders in April 2014.
2014-15: Leduc skated in the ECHL in his first pro season — making his pro debut and skating in 44 games for the Stockton Thunder before finishing the year with the Colorado Eagles. He scored 3 goals with 2 assists and was -11 with 85 penalty minutes playing for the last-place Thunder. Leduc was re-called by the AHL’s Bridgeport Sound Tigers in March but did not play in any games and was assigned to the Eagles to finish the year. Leduc scored 1 goal with 1 assist and was -3 with 10 penalty minutes in 11 regular season games with Colorado. The Eagles finished third in the Pacific Division and lost to Ontario in a seven-game first-round playoff series. Leduc was -1 with no points and 2 penalty minutes in four playoff games.
Leduc is a towering blueliner who uses his frame to his advantage. Surprisingly mobile for such a large player, he is at his best when focusing on a simple, no nonsense, defense-first game. Leduc showed tenacity and determination in working his way back from his season-ending injury in 2012-13 and was a physical force for Rimouski in his final QMJHL season. He is capable of playing plenty of minutes in a shutdown role.
Leduc continues to work to crack the lineup for the AHL's Bridgeport Sound Tigers in 2015-16 but has struggled to find ice time. He has also spent time with the Missouri Mavericks in the ECHL. Leduc's size makes him an imposing presence but with a deep group of prospects in the Islanders' pipeline he faces long odds to one day reach the NHL.
