Morrison left the NHL in 1955 and became referee-in-chief of the Western Hockey League, while also working games as a referee.
In 1986, Morrison became the NHL's vice-president of project development, assigned to the Hockey Hall of Fame where he was made president.
He served in that role until 1991 when he became chairman of the Hall, while his NHL vice-president title was dropped in 1992.
Morrison led the Hall of Fame through its relocation from the grounds of Exhibition Place to its present site in downtown Toronto, and retired in 1998.
Morrison's son, Perry, was one of 84 workers to die aboard the oil-drilling rig Ocean Ranger when it sank with no survivors off the coast of Newfoundland in 1982.
