Canadian Tire Motorsport Park (formerly Mosport Park and Mosport International Raceway) is a multi-track motorsport venue located north of Bowmanville, in Ontario, Canada, east of Toronto. The facility features a , 10-turn road course; a advance driver and race driver training facility with a skid pad (Driver Development Centre) and a kart track (Mosport Karting Centre Inc., previously "Mosport Kartways"). The name "Mosport", a portmanteau of Motor Sport, came from the enterprise formed to build the track. History The circuit was the second purpose-built road race course in Canada after Westwood Motorsport Park in Coquitlam, British Columbia, succeeding Edenvale (Stayner, Ontario), Port Albert, Ontario's Green Acres (ex-British Commonwealth Air Training Plan), and Nanticoke, Ontario's Harewood Acres (ex-British Commonwealth Air Training Plan Number One Bombing and Gunnery School), all airport circuits, as Ontario racing venues. The track was designed and built in the late 1950s. The first race to be held on the track was a local event organized by the Oakville Light Car Club in June 1961. Shortly thereafter, on June 25, the venue held its first major race, the Player's 200, a sports car race bringing drivers from the world over to rural Ontario. Stirling Moss won the two-heat event in a Lotus 19. Second was Joakim Bonnier with Olivier Gendebien third. The proposed hairpin was expanded into two discrete corners, to be of greater challenge to the drivers and more interesting for the spectators, at his suggestion, and is named Moss Corner in his honour. This is a source of lingering confusion as many people call the track Mossport. Unlike many historic motorsport venues, Mosport's track layout has remained mostly unchanged from its original form. For 2001, the entire circuit was repaved to meet FIA specifications, and is now wide. Drivers were consulted to ensure the character of the "old" track was kept; almost all the "racing lines" have been maintained. Mosport achieved acclaim through a series of international sports car races under the title "Canadian Grand Prix" normally reserved for Formula 1 races. Many events were wildly popular, breaking Canadian sports attendance records with each successive race. The success of these races led Mosport to be seen as a key component in the founding of the Can Am Series. The CanAm first visited the track in its inaugural season in 1966, and Mosport hosted at least one event in every year of the series' history, except 1968.
