Sunday 30th September 1979
Alan Jones in a Williams recorded his fourth win in five races at the Canadian Grand Prix, successfully fighting off a determined challenge from Gilles Villenenuve in a Ferrari. Jones said afterwards his strategy was to let Villenenuve set the pace and then challenge “if everything felt OK with my car”. On the 44th lap Jones outbraked Villeneuve at a hairpin and was never headed. Only ten of the 24 starters completed a race in which Ricardo Zunino made an unexpected debut after Niki Lauda had suddenly retired on the Friday.
