The Canadian Grand Prix (known in French as the Grand Prix du Canada) is an auto race held in Canada since 1961. It has been part of the Formula One World Championship since 1967. It was first staged at Mosport Park in Bowmanville, Ontario as a sports car event before it alternated between Mosport and Circuit Mont-Tremblant, Quebec after Formula One took over the event. After 1971 safety concerns led to the Grand Prix moving permanently to Mosport. In 1978 the Canadian Grand Prix moved to its current home on Île Notre-Dame in Montreal.

In 2005, the Canadian Grand Prix was the most watched Formula One GP in the world. The race was also the third most watched sporting event on the planet, behind the first place Super Bowl XXXIX and the UEFA Champions League Final.
The early Canadian Grand Prix was one of the premier events of the new Canadian Sports Car Championship, a series which had been created alongside the Canadian Grand Prix at Mosport in 1961. Several international sports car as well as Formula One drivers participated in the event. For the first five years, the event would be won by drivers with either prior Formula One experience, or would enter the championship after winning the Canadian Grand Prix. In 1966 the Canadian-American Challenge Cup ran the event, with American Mark Donohue winning. Formula One took over the following year, although the CSCC and Can-Am series continued to compete at Mosport in their own events.

The first winner in Montreal was Quebec native Gilles Villeneuve who died in 1982 on the final qualifying lap for the Belgian Grand Prix. A few weeks after his death, the race course in Montreal was named Circuit Gilles Villeneuve after him. Gilles Villeneuve was one of the first inducted into the Canadian Motorsport Hall of Fame, and the only Canadian winner at the Circuit Gilles Villeneuve.
