CTMP's 2025 major event schedule closes out with a bang on August 29-31, as two of our more popular series share top billing on the last big summer long weekend - the NASCAR Canada Series and the Trans Am Series presented by Pirelli.

The NASCAR Canada Series always delivers excitement as Canada's best stock car drivers battle hard on the legendary Grand Prix circuit for valuable championship points in Sunday's feature, the WeatherTech 200.

The Trans Am Series features North American heart-pounding muscle cars like Camaros, Corvettes, Challengers and Mustangs.

The race lineup includes the Nissan Sentra Cup and the Emzone Radical Cup Canada presented by Michelin.

Founded in 1967, the Grand Prix de Trois-Rivières is the largest motor racing event to be held on a street circuit in America.

Often nicknamed "America's Little Monaco," it presents a thrilling racing program year after year. Recognized throughout the world, the Grand Prix de Trois-Rivières has carved out a prominent place in the racing industry, notably by serving as a springboard for several great Formula 1 drivers over the past 35 years.
