De 1981 Canadian Grand Prix werd gewonnnen door Jacques Laffite van Ligier. Ondanks pole positie getrained te hebben in Canada, kon Nelson Piquet dit niet omzetten in een overwinning.
De race in Canada was ronde 14 van 15 van het 1981 seizoen.
The 1981 Canadian Grand Prix was a Formula One motor race held on 27 September 1981, at Montreal. Jacques Laffite won the race 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.
