1981 Canadian Grand Prix

Prior to the race, Alan Jones announced that he was retiring from the sport after clinching the title the previous year. Rumors were also spreading around in paddock that Niki Lauda had tested for McLaren at Donington Park and that he was planning a comeback.

Nelson Piquet clinched pole with a time of 1:29.221, with rival Carlos Reutemann alongside him on the front row. The top ten were completed by: Jones, Prost, Mansell, Rebaque, de Angelis, Arnoux, Watson and Laffite respectively.

The race start was marred with bad weather. Immediately after the start, Jones took the lead after a minor collision with Reutemann which left Reutemann behind. Toward the middle of the pack, Arnoux and Pironi had a collision with resulted in Arnoux spinning out of the race. On lap 7, Jones spun and Piquet had to take evasive action, resulting in both drivers dropping down the pecking order. Prost took the lead with Laffite, who had climbed from tenth, second. Prost's lead did not last long, as Laffite overtook him on lap 13, and kept the lead to the end of the race.

Villeneuve had a minor accident that damaged his front wing. The wing flew up only to be stuck up in the air, blocking Villeneuve's race-line vision. With his forward vision impaired, he used his peripheral vision to navigate using the yellow track markers as reference. After racing this way for minutes he used vibration on the ribbed curbing, to the point it flew off the car. This way he managed to keep control until the end of the race, without a front wing and under the rain.[3]

Prost was eventually overtaken by Villeneuve and Watson, before retiring with an accident on lap 48. Watson was able to catch and pass Villeneuve a few laps later and the two finished second and third respectively, with Villeneuve clinching his third and last podium of the year on home soil. Bruno Giacomelli of Alfa Romeo, who had started fifteenth, came home fourth, with pole-man Piquet coming in behind him.
