The 1979 Canadian Grand Prix was a Formula One motor race held on 30 September 1979 at the Circuit Île Notre-Dame, Montreal.
During practice Niki Lauda announced his retirement from Formula One.
The organizers would not let the Alfa Romeo factory 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.
As of 2024, Regazzoni's podium remains the last for a Swiss driver in Formula One.
