2010-11:John Gilmour left his native Montreal to play prep school hockey at Gilmour Academy in Ohio. He had 44 points in 62 games for Gilmour Academy, which captured the Mid-America District title and advanced to USA Hockey's U18 National tournament. In four games at the national championships he had 2 assists and 2 penalty minutes. The Lancers lost to the Colorado Thunderbirds, 2-0, in the quarterfinals.
2011-12: Gilmour played for the USHL's Cedar Rapids RoughRiders and in February committed to playing college hockey at Providence in 2012-13. In 58 games he had an even plus/minus and scored 10 goals with 14 assists and 14 penalty minutes. The RoughRiders finished fifth in the Eastern Conference. In two playoff games Gilmour had 1 assist and was -3.
2012-13: Gilmour made the jump from the USHL to college hockey, skating in 38 games for Providence as a freshman. He scored 4 goals with 9 assists and was +3 with 35 penalty minutes. Providence was fifth in Hockey East, finishing with a winning record for the first time since 2003-04, and won a first round playoff series against New Hampshire. In his third year of draft eligibility, Gilmour was not among the 210 North American skaters in Central Scouting's final rankings. He was selected by Calgary in the seventh round (198th overall) of the 2013 NHL Draft.
Gilmour is a solid defender despite his 5’11 and 175-pound frame. He is a strong, fast skater and possesses a strong shot from the point. Gilmour also has an offensive side to his game and saw time on the power play unit for the Providence Friars. The Montreal native has the hockey IQ and composure to become an effective blueliner.
Gilmour enters his sophomore season with the Providence Friars as 2013-14 begins. His maturity as a player continues to grow and another year in the Friars system to develop will help further his play as a defender. Gilmour will be expected to increase his presence on the ice, defensively and offensively, considering he has the talent and skill set to do so. In three games this season he has three points already. Gilmour will have a few more years as a collegiate player to develop his game for the next level.
