2010-11: Alexis Pepin appeared in his first midget AAA game as a 15-year-old — playing most of the seasons with the Predateurs du St. Laurent bantam team — and attended the initial NHLPA All-Canadians Mentorship Camp in August. He had no points with 8 penalty minutes in his only game with College Charles-Lemoyne.
2011-12: Pepin led College-Charles Lemoyne in goals and points in his first season in midget AAA hockey. He scored 22 goals with 18 assists in 38 games and was third on the Riverains with 93 penalty minutes. Pepin was the second player taken in the 2012 QMJHL Entry Draft after Sherbrooke selected Donald Audette — being chosen in the first round by Prince Edward Island.
2012-13: Pepin played in the Quebec Major Junior Hockey league as a 16-year-old and represented Canada Quebec in the 2013 U17 World Hockey Challenge. In 64 regular season games with Prince Edward Island he scored 18 goals with 12 assists and was minus-9 with 78 penalty minutes. The Rocket finished third in the Maritimes Division; falling to Val d’Or in six games in a first round series. Pepin scored 1 goal with 1 assist and was minus-2 with 4 penalty minutes in six playoff games. In six games for Canada Quebec at the WHC he scored 3 goals with 4 assists and 18 penalty minutes.
2013-14: Pepin played for Canada’s gold medal U18 team at the 2013 Ivan Hlinka Memorial tournament in August before returning to Charlottetown for his second junior season. After a slow start he was traded to Gatineau in January 2014. Pepin scored 8 goals with 9 assists and was minus-8 with 58 penalty minutes in 37 games with the re-christened Islanders before the trade. In 23 regular season games with Gatineau he scored 9 goals with 8 assists and was plus-7 with 11 penalty minutes. The Olympiques finished fourth in the West Division and advanced to the second round in the playoffs. Pepin scored 4 goals with 1 assist and was plus-4 with 4 penalty minutes in eight playoff games. He had no points nor penalty minutes in five games at the Ivan Hlinka Tournament. Canada defeated the USA, 4-0, in the gold medal game. Pepin was ranked 110th amongst North American skaters in the Central Scouting final rankings and was invited to the NHL Scouting Combine in May. He was selected by Colorado in the fourth round (114th overall) in the 2014 NHL Draft.
2014-15: Pepin began the year with Gatineau and was once again involved in a mid-season trade; going to Val-d’Or in January in exchange for defenseman Gabriel Bilodeau and two draft picks. In 24 games with the Olympiques he scored 10 goals with 4 assists and was -6 with 20 penalty minutes, scoring 6 of his 10 goals on the power play. He skated in 23 regular season games for Val-d’Or and scored 8 goals with 5 assists, finishing +2 with 36 penalty minutes. Pepin scored one of the biggest goals of the season for the Foreurs, netting the game-winner in overtime of Game 7 of the second-round series against Baie-Comeau. Val-d’Or was swept by Rimouski in the QMJHL semifinals. Pepin finished with 4 goals and 4 assists and was +3 with 37 penalty minutes in 17 playoff games.
Pepin has all of the tools but has yet to produce at the level of which his skill set suggests he is capable. With the requisite size, skating ability, and technical skills that suggest he should dominate at the junior level, some have questioned his work ethic and consistency.
Pepin is now in his fourth QMJHL season and first full season with the Val-d'Or Foreurs in 2015-16. Drafted in 2014, he must be signed by the Avalanche by June or would re-enter the 2016 NHL Draft. Pepin's combination of size and goal scoring are intriguing and he has put up decent numbers and shown some toughness for a Val-d'Or squad that is dominating the QMJHL. Whether that is enough to earn him an entry-level contract is still uncertain. The Colorado organization has several forward prospects and it is equally likely that Pepin begins his pro career on an AHL deal somewhere or returns to the QMJHL for an overage season in 2016-17.
