The Hockey Hall of Fame and the Western Hockey League's Vancouver Giants on Monday confirmed that Quinn died on Sunday night at Vancouver General Hospital after a long illness.
Quinn was a co-owner of the Giants and the Hall of Fame's chairman of the board as well as a longtime member of its selection committee.
"We are deeply saddened by the passing of Pat Quinn”, said Jim Gregory, vice-chairman of the Hockey Hall of Fame, in a statement. "Pat is one of hockey's most respected individuals whose lifetime involvement as a player, coach and executive has made an indelible mark on the game, and our thoughts and prayers are with [Quinn's wife] Sandra and all of Pat's family and friends at this extremely difficult time."
Quinn, who was born in Hamilton, Ont., played nine seasons as a defenceman in the NHL. He scored only 18 goals but was recognized for his toughness and size.
Quinn was an NHL head coach for 20 seasons with five different teams, most recently the Edmonton Oilers in the 2009-10 season. He also served stints behind the bench with Philadelphia, Los Angeles, Vancouver and Toronto.
He was also the head coach of the Canadian men's team that won Olympic gold in 2002 in Salt Lake City.
