 When the mid-sized Chevrolet Chevelle was introduced in 1964 it was sold in Canada as the Acadian Beaumont ('Beaumont' was formerly the top-level trim of Chevy II-based Acadian), and in 1966 Beaumont became its own marque.The Beaumont-badged Chevelles were in production in Canada until 1969.Even after the 1965 Autopact (and Canada–United States Free Trade Agreement that replaced it in 1988) the practice of building Pontiac-badged Chevrolets for sale at Canadian dealers continued until the brand was discontinued in 2010.
