On October 12, 1989, during half time of an exhibition match between the AFL teams Melbourne Demons and Geelong Football Club in Toronto, footy jumpers were presented to the team captain of the Mustangs.
Two days later the Mustangs were defeated by the Panthers 65 to 48, winning the inaugural Conacher Cup.
In 1999, the Brampton Wolverines disbanded due to a shortage of players, with the remaining players joining the Mississauga Mustangs.
In 2004, the team was renamed the Demons, and adopted the identity of the Melbourne Demons AFL club.
In 2007, the club relocated to High Park and changed their name.
