The three H16 BRMs of Stewart, Spence and Irwin were together on the grid in ninth, tenth and eleventh place for the Canadian Grand Prix, and at the start all three cars gained places, the weight of the engine perhaps providing added traction in the wet conditions. Irwin climbed as high as seventh before falling back and ultimately spinning off after 18 laps. Spence again got the car to the finish and after running in eighth for much of the race a spate of late problems for others lifted him to fifth place, three laps down but two places ahead of Bruce McLaren, who had impressed running second in a car powered by the BRM V12 that would replace the H16 for 1968.
