The Canadian Grand Prix () is an annual motor racing event held 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 alternating 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, after similar safety concerns with Mosport, the Canadian Grand Prix moved to its current home at Circuit Gilles Villeneuve on Notre Dame Island in Montreal. In 2005, the Canadian Grand Prix was the most watched Formula One Grand Prix in the world. The race was also the third most watched sporting event worldwide, behind the first place Super Bowl XXXIX and that year’s UEFA Champions League Final. The 2020 and 2021 events were cancelled due to the COVID-19 pandemic. After the cancellation of 2021 Canadian Grand Prix, the contract was extended to 2031. History 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 Park near Toronto in 1961. Mosport Park (which is still in its original layout configuration) was a spectacular and challenging circuit which had many ups and downs; the circuit was popular with drivers. 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. Formula One Mosport Park and Mont-Tremblant The event was run as part of the Formula One world championship first in 1967; Mosport Park was selected as the venue for the event. The Ontario circuit alternated with the Circuit Mont-Tremblant in Quebec, where the Canadian Grand Prix was held in 1968 and 1970. Mont-Tremblant, located hours northwest of Montreal, was much like Mosport Park in that it was a spectacular circuit which had significant elevation change and was very challenging. The first championship race was held between the German and Italian rounds on
