The 1974 Canadian Grand Prix was a Formula One motor race held at Mosport Park on 22 September 1974.

It was race 14 of 15 in both the 1974 World Championship of Drivers and the 1974 International Cup for Formula One Manufacturers.

[4] Niki Lauda was on course for victory, until running over debris on lap 67, causing his Ferrari to spin into barriers, having led the whole race until that point.

Jacques Laffite was also forced out due to picking up a puncture, possibly caused by the same debris on the circuit.

Emerson Fittipaldi grabbed the advantage, and led for the rest of the race.
