The Canadian Grand Prix (known in French as the Grand Prix du Canada), is an annual auto race held in Canada starting in 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 ?le Notre-Dame in Montreal.

In 2005, the Canadian Grand Prix was the most watched Formula One GP in the world.
