The Sanair superspeedway is a strange short tri-oval which briefly held a round of the Champ Car World Series at the behest of the Molson brewery. The dragstrip dates back to 1970 with a 1.243-mile road course added two years later. A smooth new 0.826-mile speedway was built in 1983 although the inaugural Champ Car race in 1984 was marred by the severe injured Rick Mears sustained to his legs. It was far too tight for such powerful open wheel cars and Molson switched its sponsorship from Sanair to a new race in Toronto. The dragstrip is now used more often, and snowmobile races are held in the winter.
