2009-10: Ryan Culkin skated for the Lac Saint-Louis Lions midget AAA team in Quebec. In 19 regular season games he scored 4 goals with 2 assists and 10 penalty minutes and in 21 playoff games had 1 goal with 1 assist. Culkin was selected by the Quebec Remparts in the seventh round (122nd overall) of the 2010 QMJHL Entry Draft.
2010-11: Culkin played 40 games for Quebec in his first QMJHL season. The Remparts finished with the third-best record during the regular season and Culkin chipped in with 6 goals and 5 assists and was plus-one with 12 assists. Quebec reached the playoff semifinals and Culkin's role steadily increased. He skated in all 18 playoff games and was plus-seven with 5 assists and 4 penalty minutes.
2011-12: Culkin appeared in 60 games for the Remparts in his second season. He scored 6 goals with 19 assists and was plus-nine with 28 penalty minutes. Quebec reached the second round after finishing third in the East Division during the season. In 10 playoff games Culkin had 7 assists and was plus-nine with 8 penalty minutes. He was invited to the NHL Draft Combine and ranked 66th amongst North American skaters in Central Scouting's final rankings prior to the 2012 NHL Draft.
A hard-working two-way blue liner, Culkin has steadily improved during his time in the QMJHL. A strong skater with a low panic threshold, these skills serve him well at both ends of the ice. Sometimes guilty of trying to do too much on the ice, he has good size and has become more confident moving the puck as well as carrying it on the rush.
Culkin will play his third season in the QJMHL with Quebec Remparts where the 5th rounder will be expected to play big minutes and on both specialty teams. The puck moving defender needs to bring more offense from the backend and play with more physicality each game. He should have a few years of development at the junior level to improve his overall game.
