Sunday 19th September 1971
Jackie Stewart underlined his credentials with victory in a Canadian Grand Prix to record his sixth win of a season in which he had the drivers’ championship done and dusted by August. The race had to be stopped after 64 of the scheduled 80 laps because track marshals were unable to see each other through the rain and mist. The day was overshadowed by the death of 37-year-old local driver Wayne Kelly in a Formula Ford race earlier on, the accident causing a delay to the start of the grand prix. And in England, Peter Hawtin died when he crashed his Cooper in a race at Oulton Park.
