There was a 4-week gap between the Monaco and Canadian Grands Prix as the Belgian Grand Prix at Spa-Francorchamps was postponed until September, after the newly-laid track surface, to help deal with wet weather, melted due to the hot weather conditions. The Canadian Grand Prix at the Circuit Gilles Villeneuve in Montreal produced a Ferrari 1–2, with Alboreto winning ahead of Johansson, and Prost finishing third. It was Ferrari's first 1–2 since the 1983 Dutch Grand Prix and their last until the 1987 Australian Grand Prix.
