The 1978 Canadian Grand Prix was a Formula One motor race held on 8 October 1978 at Montreal. This was the 16th and final race of the 1978 World Championship of F1 Drivers and the International Cup for F1 Constructors. It was Ferrari driver Gilles Villeneuve's and a Canadian driver's first victory in Formula One.
Report
Background
The Canadian Grand Prix had moved from the Mosport Park circuit near Toronto to the newly built Circuit Île Notre-Dame in Montreal. The event had moved because of track safety and organization problems with the hilly and scenic Mosport Park track. This circuit, made up entirely of public roads was located on a man-made island in the middle of the St. Lawrence Seaway which was the location of Expo '67 and rowing at the 1976 Summer Olympics.
Before the race, in pre-race interviews Mario Andretti noted that he thought that the circuit has been designed in favour of Gilles Villeneuve, a comment that was picked up by local press. Andretti responded to the comments on race day morning, stating that he is "not critical of the race organizers", but instead "critical of our own FOCA officials who were sent over here to approve the track".
Both championships were already sewn up (in favour of Andretti and Lotus), so this, the final round, was a dead rubber in the 1978 title chase. Before the race, Brabham announced that rising star Brazilian driver Nelson Piquet, who had raced earlier in the season with Ensign and BS Fabrications, would be joining them in a third car, alongside regular drivers Niki Lauda and John Watson. The only other change was that Riccardo Patrese returned to the Arrows cockpit after missing the previous race.
Practice and qualifying
Poor weather and rain on Friday morning meant that the first practice session began 20 minutes later than scheduled.
