McGregor was born in Forest, Ontario on March 11, 1994, to parents Dean and Trudy.[2] Growing up in Forest, Ontario, he started playing ice hockey when he was three years old and advanced to able-bodied AAA hockey, breaking his leg in a game in 2009 which ultimately led to a diagnosis of spindle cell sarcoma, a form of bone cancer.[1][3] As a result, in January 2010 McGregor underwent eight months of chemotherapy and the amputation of his left leg above the knee.[2]
Career
Upon concluding treatment, McGregor was encouraged to try out sledge hockey by his former coaches.[4] He started playing with a standing amputee team but soon switched to sledge hockey.[2][1] McGregor began playing sledge hockey in 2011 and made the Canadian men's national para ice hockey team in 2012.[5] In his international debut at the age of 18, he recorded a goal and two assists to help Team Canada win a silver medal at the 2012 World Sledge Hockey Challenge.[6] The following year, McGregor became the youngest member of Team Canada to win a gold medal at the 2013 IPC Ice Sledge Hockey World Championships.[7]
As a result of his success, McGregor was the second-youngest player named to Team Canada’s sledge hockey team for the 2014 Winter Paralympics,[5] where he won a bronze medal.[8] Following this, he collected 11 goals and 10 assists in six games during the 2015 International Ice Sledge Hockey Tournament to win a gold medal.[9][10]
