Riverside International Speedway is a 1/3 mile, high banked, asphalt short track located in James River, Nova Scotia, Canada, about ten kilometers southwest of the town of Antigonish.

Riverside is the only stock car racing facility in Canada east of Quebec to be sanctioned by NASCAR, hosting the NASCAR Canadian Tire Series annually since its inception in 2007; and with its NASCAR affiliation reaching back into the early 80s when it hosted the NASCAR Busch East Series, Riverside’s NASCAR roots reach back further than any other active track in the country.
