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. 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 42 feet (12.8 m) 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 in 1966, and Mosport hosted at least one event in every year of the series’ history, except 1968. In 1967, Canada’s centennial year, Mosport hosted Formula One, USAC, and a 500cc Motorcycle Grand Prix. F1’s Grand Prix of Canada remained at the track until 1977, until it was moved to Montreal. Mosport has hosted a wide variety of series throughout its history.

Due to significant scheduling demands on the original grand prix circuit, the original academy course was reconstructed and lengthened to a full racing course in the fall of 2013. The new track features two configuration options; a 2.2-kilometre (1.4 mi) intermediate course, a 2.9-kilometre (1.8 mi) advanced course, as well as a skid pad, a pit lane, and a multi-storey event centre with classrooms and other facilities.
