Sunday 27th September 1981
Jacques Laffite won the Canadian Grand Prix driving for Ligier. It would prove to be Ligier’s last race win for fifteen years, until the 1996 Monaco Grand Prix. Williams clinched the 1981 Constructors’ Championship with one race left, as the two points scored by the Brabham team were not sufficient to allow them to catch Williams in the final race. This was also the last time the Canadian Grand Prix was held at the near-end of the season.
