He was selected by the Montreal Juniors in the third round (42nd overall) of the 2011 QMJHL Entry Draft.
2011-12: Clapperton played in his first QMJHL season for the re-named and re-located Blainville-Boisbriand Armada (formerly Montreal Juniors).

Clapperton scored 3 goals with 6 assists and was +6 with 8 penalty minutes in 11 playoff games. He was ranked 199th amongst North American skaters in Central Scouting's final rankings but was not selected in the 2012 NHL Draft.
2012-13: Clapperton attended the Philadelphia Flyers summer prospect camp before returning to Blainville-Boisbriand for his second season. Clapperton was the second-leading scorer for the Armada, which won the West Division for the second straight season and reached the QMJHL semifinals. Skating in 67 of 68 regular season games, Clapperton scored a team-leading 34 goals with 43 assists and was +17 with 71 penalty minutes. In 15 playoff games he scored 6 goals with 14 assists and was +1 with 20 penalty minutes. Not among the 210 players in Central Scouting's final rankings, he was selected by Florida in the fifth round (122nd overall) in the 2013 NHL Draft.
Clapperton is a goal-scoring winger who relies on good hockey sense and hard work to generate opportunities. He is smaller than most NHL players, and lacks substantial footspeed, but he has the kind of determination to score that coaches and scouts like to see.
Clapperton will play another season for the Armada in the QMJHL. His future potential will be limited by his size and lack of quickness, but he could easily become a scoring-line forward in the AHL.
