Track map and layout
Better known to generations of Canadian racers by its original name Mosport, Canadian Tire Motorsport Park's Grand Prix Circuit is a fast, undulating natural-terrain road course cut through rolling farmland east of Toronto. The lap climbs and dives through blind crests and off-camber sweepers, with the uphill run to Turn 2 and the plunging drop into the Moss Corners among the most respected sections in Canadian motorsport. The circuit's flowing, high-speed character rewards commitment and has changed comparatively little since the 1960s, which is part of why it remains a favourite among drivers across IMSA, NASCAR Canada and club racing. Beyond the Grand Prix Circuit, the property also houses the shorter Driver Development Track used for lapping days and driver training, and a separate karting complex.

History of Canadian Tire Motorsport Park
From farmland to Mosport
The circuit opened in June 1961 as Mosport Park, carved from rolling farmland northeast of Toronto near Bowmanville. Its natural, undulating terrain and minimal reshaping set it apart from many purpose-built tracks of the era, and it quickly became one of the toughest and most respected road courses in North America among drivers of the day.
F1, Can-Am and the Mosport era
Mosport hosted the Formula 1 Canadian Grand Prix on several occasions through the 1960s and 1970s, sharing the race with Circuit Mont-Tremblant before the event settled permanently in Montreal. The track was also a mainstay of the Can-Am sports car series for most of its run between 1966 and 1986, and hosted World Superbike races in the early 1990s, cementing its reputation as one of Canada's premier road racing venues.
Renaming and the modern IMSA era
The facility was renamed Mosport International Raceway in 1997 and again to Canadian Tire Motorsport Park in 2012 after the retailer took a sponsorship and naming stake, though many longtime fans still call it Mosport. The track was resurfaced to FIA specifications in 2001 and has continued to attract top-level competition, becoming a regular stop on the IMSA WeatherTech SportsCar Championship and NASCAR Canada Series calendars. Today the property combines the historic Grand Prix Circuit with a separate Driver Development Track and karting complex, giving both professional series and everyday track-day drivers a place to lap one of Canada's oldest and most storied circuits.
