The 1979 Canadian Grand Prix was a Formula One race held on 30 September 1979 at Montreal. During practice Niki Lauda announced his retirement from Formula One. Ricardo Zunino replaced him for the race. The organizers would not let the Alfa Romeo team compete unless they pre-qualified. They refused to do so but a compromise was reached where one of their drivers would be allowed to take part in practice. The other, Bruno Giacomelli, was not allowed to enter the race. The race turned into a close duel between Alan Jones and Gilles Villeneuve that continued the entire race.
