2009-10: Kurtis MacDermid played minor midget hockey with the Grey-Bruce Highlanders in Central Ontario. MacDermid was selected by the Owen Sound Attack in the seventh round (139th overall) of the 2010 OHL Priority Draft.
2010-11: MacDermid skated for the Owen Sound Grays in the GOJHL. He was the leading scorer among defensemen for the Grays; finishing with 6 goals and 16 assists with 124 penalty minutes while playing all 51 games. The Grays finished last in the Midwestern Conference; winning just four games.
2011-12: MacDermid made his OHL debut; appearing in nine games due to a bout with mononucleosis, a season-ending injury in January and the presence of several veteran defensemen in the Owen Sound lineup. He had 2 assists and was an even plus/minus with 7 penalty minutes. He also returned to the Grays, skating in 20 games, and had 3 goals with 6 assists and 80 penalty minutes. The Greys missed the GOJHL playoffs; finishing last in the Midwestern Conference. MacDermid attended the Kings' prospect camp in July after passing through the 2012 NHL Draft without being selected and signed a three-year entry-level contract with the Kings in September, 2012.
2012-13: MacDermid skated in 65 games for Owen Sound in his first full season in the OHL. He scored 1 goal with 7 assists and was +7; finishing second on the Attack with 110 penalty minutes. Owen Sound finished second to OHL champion London in the Midwest Division and reached the second round in the playoffs. MacDermid had 3 assists and was +3 with 11 penalty minutes in 12 playoff games.
MacDermid is a no nonsense, physically-punishing defenseman. Despite being 6’1 and 170 pounds, he likes to take the body and drop the gloves in defense of his teammates and to get the energy going. He has limited to no offensive upside and relies primarily on his average defensive game and physicality.
MacDermid will return to the Owen Sound Attack for his third year with the team.
