The Ontario Australian Football League is the largest Australian rules football league in North America. It is currently composed of teams from the Greater Toronto Area and Southwestern Ontario, who play off for the Conacher Cup (named after Lionel Conacher, the greatest all-round athlete in Canadian sports history), presently awarded to the winner of the annual OAFL Grand Final.
The league began as the Canadian Australian Football Association in May 1989. Two teams were formed that year - the Mississauga Mustangs and the Toronto Panthers.
