Like all Canadian Pontiacs built from 1955 to 1970, Laurentians used full-size Chevrolet chassis, drive trains, and other parts, but using a body shell similar in style to, but not interechangeable with, the U.S. Catalina. For example, a 1964 Pontiac Laurentian looks like a Catalina, but has more in common with the Chevrolet Bel Air. Through at least 1967, however, the Laurentian wore the three "stars" normally associated with the Pontiac Star Chief/Executive series, even though other exterior trim pieces were similar to the Catalina.
