Acadian
The Acadian was Canada's equivalent of the U.S. Chevy II & Chevelle and was produced so Canadian Pontiac-Buick dealers would have a compact car to sell.
A Beaumont was a trim level of the Acadian line from 1962 to 1965.
The Acadian from 1962 to 1969 was based on the Chevrolet Chevy II /Nova. In 1964 and 1965, the Acadian-Beaumont was based on the Chevelle A-body platform. In 1966 the Acadian was Chevy II/Nova-based and the Beaumont was Chevelle-based.
The Beaumont became its own brand in 1966 without the Acadian name. The Beaumont featured minor styling changes from the U.S. Chevelle with a Pontiac-style grille. The interior and instrument panel was from the U.S. Pontiac Tempest/LeMans/GTO series. The drivetrain was all Chevelle with the exception of the 396/375hp engine that was not available. The Beaumont line was discontinued after 1969.
The Canso Sport Deluxe was similar to the Chevy II Super Sport. The 1966 Canso was the only year the RPO L79 engine was available.
The Sport Deluxe (SD) is the equivalent of the Malibu SS and SS396 where applicable.
