After the Second World War the Pontiac brand continued to be very popular, and the product line was further harmonized with the Canadian Chevrolet products. In the late 1940s and early 1950s the US market embraced eight-cylinder engines and US Pontiacs equipped with the straight-eight engine were popular, but in Canada the straight-six continued to be the popular offering. Beginning in 1953 the model lineup consisted of the base "Pathfinder", mid-range "Pathfinder Deluxe", and top-of-the-line "Laurentian". The chassis was shared with the Chevrolet, and interiors were a combination of Chevy and Pontiac parts.
