2009-10: Marc-Olivier Roy played 42 games for the Saint-Eustache Vikings in his first season in Quebec midget AAA hockey. He scored 9 goals with 14 assists and had 6 penalty minutes. In six playoff games he scored 1 goal with 4 assists and had 2 penalty minutes. Roy was selected by the Montreal Juniors in the third round (49th overall) of the 2010 QMJHL Entry Draft.
2010-11: Roy played three QMJHL games with Montreal and was the second-leading scorer for Saint-Eustache in his second season with the Vikings. He had 1 assist and was -1 with the Juniors. Roy scored 22 goals with 25 assists in 38 games for the Vikings – with his 47 points trailing only Anthony DeLuca (53). Saint-Eustache reached the provincial semifinals and Roy was third amongst all scorers in the playoffs with 11 goals and 14 assists in 10 games.
2011-12: Roy skated in 63 games for the re-located and re-named Blainville-Boisbriand Armada in his first full QMJHL season. He scored 17 goals with 22 assists and was +26 with 29 penalty minutes. The Armada finished first in the West Division and reached the second round in the playoffs. Roy scored 6 goals with 8 assists and was +11 with 14 penalty minutes in 11 playoff games.
2012-13: Roy was the Armada’s third-leading scorer in his second season as Blainville-Boisbriand again finished first in the West Division. He scored 29 goals with 38 assists and was +12 with 68 penalty minutes in 65 games. The Armada reached the playoff semifinals and Roy scored 6 goals with 13 assists, finishing +4 with 10 penalty minutes, in 15 playoff games. He was ranked 54th amongst North American skaters in the Central Scouting final rankings and was selected by Edmonton in the second round (56th overall) in the 2013 NHL Draft.
2013-14: Roy was plagued by injuries and inconsistency in his third QMJHL season with Blainville-Boisbriand. An elbow injury suffered in the pre-season while with the Oilers kept him out of the lineup until November 1st and he later missed nearly six weeks after suffering a concussion. In 39 regular season games with the Armada he scored 14 goals with 21 assists and was +6 with 39 penalty minutes. Blainville-Boisbriand finished second to Memorial Cup-bound Val-d’Or in the West Division and reached the QMJHL semifinals; falling to Baie-Comeau, 2-1, in a decisive seventh game. Roy scored 4 goals with 8 assists and was an even plus/minus with 14 penalty minutes in 20 playoff games. In May 2014 he was acquired by the Quebec Remparts from the Armada in exchange for two draft picks in a QMJHL trade.
Roy has the ideal height of an NHL center with a high level of natural skill and talent but will need added strength and bulk to compete at the NHL level. He is willing to dig deep into tough areas of the ice when it comes to creating scoring chances but that doesn’t always translate to 100 percent effort on every shift. He will need to continue to hone his two-way game and responsibility in his own end to have success at the pro level. Roy’s main strength is his skating ability, as he can power through traffic in the neutral zone quite easily. His quick skating and desire to dig deep into the corners sometimes work to his detriment however, as he is sometimes caught out of position in his own end. He has a decent shot which makes him valuable on the power play.
Roy attended training camp with the Oilers before being returned to the QMJHL for an overage season in 2014-15. In his first season with the Quebec Remparts after three seasons with Blainville-Boisbriand, he has yet to sign an entry level contract with Edmonton and would re-enter the NHL Draft if not signed by June 2015. Roy's offensive skills and physical tools suggest he could provide scoring to a team in need of offense. Whether he can develop the consistency necessary to play at the NHL level is uncertain at this time.
