Secord played his junior hockey with three different teams--the Westford Raiders of the MTHL and the OHL's Hamilton Fincups and St. Catharines Fincups. He was also part of Canada's silver medal team at the World Junior Championships in 1977. The Boston Bruins selected Secord as their first choice in the 1978 Amateur Draft and was 16th overall and began playing for them the next season.
After spending two and a half-mediocre seasons with the Bruins he was traded to the Chicago Blackhawks where his career took off. His first full season with the Hawks saw Secord collect a career high in goals, assists and points while being named to the All-Star Game. Adding to his scoring touch, he racked up 303 penalty minutes on his way to becoming a feared player in the NHL. The next season, 1982-83, saw Secord top his goal and point production from the previous year with 56 goals and 86 points in 80 games while appearing in his second straight All-Star Game.
After spending seven seasons with the Blackhawks, Secord was traded to the Toronto Maple Leafs where he enjoyed a fresh start. This lasted only a season and a half, however, and he was dealt to the Philadelphia Flyers as they made a run for the Cup. In the off-season, Secord rejoined the Blackhawks after signing as a free agent for one last year with in the NHL.
Secord retired in 1990, only to come back and play with the IHL's Chicago Wolves in 1994. He played for two seasons before hanging up his skates for good.
When Secord was a teenager, he fought forest fires in Northern Ontario and fell in love with flying. During breaks from hockey, Secord took flying lessons and racked up flying time to eventually become a commercial pilot after finishing his hockey career.
