Mosport Park

Mosport Park, officially named Canadian Tire Motorsport Park (CTMP), stands as one of North America's most respected racing facilities. The circuit opened in 1961 near Bowmanville, Ontario, Canada, and became Canada's first purpose-built permanent road racing facility. The name "Mosport" combines the words "Motor Sport" into a single term. The track was constructed for approximately $500,000 and quickly earned recognition as a challenging natural-terrain road course. The original layout remains largely intact after more than 60 years of operation, preserving its reputation as a driver's circuit that demands skill and precision.

Technical Specifications and Layout

The Grand Prix Circuit measures 3.957 kilometers (2.459 miles) in length and features 10 high-speed corners. Cars run clockwise around the track. The circuit includes a dramatic elevation change of 52 meters, which creates blind crests, off-camber entries, and challenging transitions. The track was widened to 12 meters (40 feet) and completely repaved between 2000 and 2001. Engineers consulted carefully during this renovation to maintain the original racing lines and character. The natural terrain makes momentum critical, and drivers pay a high price for mistakes.

Signature Corners and Features

Moss Corner (Turns 2/5A and 5B) represents the circuit's most famous feature. Sir Stirling Moss suggested redesigning this section from a single-radius corner into a two-part complex. The corner now features a technical downhill entry followed by a tight exit. This design rewards both precision and courage. Turn 2 also carries the name Clayton Corner, while Turn 3 is called Quebec Corner. The Turn 4 and 5 complex presents a fast downhill sweep into a tight double-apex that tests commitment and car control. The Andretti Straightaway provides a long, fast section where cars reach maximum speed before heavy braking into Turn 8. This straight includes slight turns as the track rises in elevation. The lap concludes with the Turn 8-10 sequence, a rapid, flowing set of corners that demands smooth, high-speed transitions. Turn 10 is known as White's Corner.

Racing History and Major Events

Stirling Moss won the first major international race at Mosport, the Player's 200, in June 1961, driving a Lotus 19. The circuit hosted the first true World Championship Canadian Grand Prix in 1967, which Jack Brabham won. Formula 1 continued to race at Mosport until 1977, alternating with Circuit Mont-Tremblant before the Grand Prix moved permanently to Montreal. Gilles Villeneuve made his Ferrari Grand Prix debut at Mosport in 1977. The circuit hosted more Can-Am Challenge Series races than any other track. Mosport has welcomed the World Sportscar Championship, American Le Mans Series, and currently hosts the IMSA SportsCar Championship (Chevrolet Grand Prix). NASCAR Truck Series events (Chevrolet Silverado 250) and NASCAR Canada Series races have run at the facility. The track has also hosted USAC IndyCar races, Formula 5000, Grand Prix motorcycle racing, Trans-Am Series, and Canadian National Superbike Championship events. Mosport is one of only two tracks to have hosted Formula 1, IndyCar, FIA World Endurance Championship, and Can-Am races—Watkins Glen International is the other.

Modern Development and Facilities

Don Panoz acquired Mosport in 1998 and initiated major renovations, including an extended pit lane, new pit exit, enlarged run-off areas, and complete track repaving. In 2011, a consortium including Canadian racer Ron Fellows, Alan Boughton, and Carlo Fidani purchased the facility. The track was officially renamed Canadian Tire Motorsport Park in 2012. Today, CTMP operates as a multi-track venue with a Driver Development Centre (2.9 km training facility with skid pad), the Mosport Karting Centre (1.5 km kart track), and a half-mile paved oval that opened in 1989. Many successful Canadian racing drivers began their careers at Mosport, inspiring the saying: "If you can go fast at Mosport, you can go fast anywhere."
