Because of the smaller fuel tanks of the F5000 cars, the race was run in two heats of 32 laps, and the final result decided by a points system. Jackie Stewart qualified on pole for Heat 1 and finished runner-up behind Mario Andretti. Chris Amon set fastest lap. Andretti and Stewart again finished first and second in Heat 2 and Pedro Rodriguez set fastest lap, quicker than Amon's time in Heat 1. Mario Andretti was declared the winner; with Stewart in second place and Denny Hulme third. Mark Donohue was the best-placed F5000 finisher in Heat 1, and Ron Grable best in Heat 2. Grable was also the best-placed F5000 driver on aggregate.

Hopes for a regular fixture rapidly faded due to financial problems; the Questor Grand Prix remained a one-off event and the Ontario Motor Speedway was never again host to Formula One cars.
