Dougie Hamilton

Amateur

Hamilton attended Crestwood Preparatory College for grade 9 and Governor Simcoe Secondary School for grades 10–12. He played minor midget for the St. Catharines Falcons of the OMHA's South Central AAA League and was selected by his hometown Niagara IceDogs in the second round, 27th overall, of the 2009 OHL Priority Selection.

Hamilton played for the Icedogs for three-and-a-half seasons. During his time, he was teammates with future NHL players such as Ryan Strome, Andrew Shaw and Brett Ritchie. Hamilton was also teammates with his older brother Freddie, who was a fifth-round selection of the San Jose Sharks during the 2010 NHL Entry Draft.

Hamilton was ranked fourth by the NHL Central Scouting Bureau for North American skaters for the 2011 NHL Entry Draft. Hamilton was drafted ninth overall by the Boston Bruins.

On December 8, 2011, Hamilton signed a three-year, entry-level contract with the Bruins.

Boston Bruins

Hamilton began the 2012-13 season with the Icedogs. However, he was recalled by the Bruins to play for the club during the NHL's lockout shortened season. On January 19, 2013, Hamilton made his NHL debut for the Bruins in a 3–1 victory against the New York Rangers, and two games later, on January 23, Hamilton scored his first NHL point for an assist in an overtime loss against the Rangers in Madison Square Garden. On February 15, Hamilton scored his first career NHL goal against Ryan Miller of the Buffalo Sabres. Hamilton made his Stanley Cup playoff debut on May 3, replacing defenceman Andrew Ference, who was serving a one-game suspension for his illegal hit on Toronto Maple Leafs forward Mikhail Grabovski. On April 25, Hamilton was named the 44th Annual NESN 7th Player recipient, an award given to the Bruin who most exceeded all expectations that season, as voted by the team's fans.

Calgary Flames

On June 26, 2015, during the 2015 NHL Entry Draft, as an impending restricted free agent on July 1 and with the Bruins facing salary cap constraints, Hamilton was traded to the Calgary Flames in exchange for a first-round draft pick (Zachary Senyshyn) and two second-round picks (Jakob Forsbacka-Karlsson) and (Jérémy Lauzon), all in the 2015 Draft. Four days later, on June 30, Hamilton signed a six-year, $34.5 million contract with the Flames worth $5.75 million annually. On October 5, the Flames acquired older brother Freddie from the Colorado Avalanche in exchange for a conditional 2016 seventh-round pick in the 2016 NHL Entry Draft, reuniting the two.

International play

Hamilton participated at the 2012 World Junior Ice Hockey Championships held in Canada and won the bronze medal. Hamilton played for the team the following tournament, where Canada finished fourth.
