An Architectural Products Division was formed in April 1959. Its purpose was to provide design, engineering and manufacturing service for the construction industry. Its main product was its curtain wall.

Le Cartier Curtain Walls: In curtain wall construction the outer surface of the building consists of panels, approximately 1.2 m high by 1.4 m wide (4 ft. x 4.5 ft.), made of aluminum, steel and glass. Hung on the basic steel and concrete structure like a curtain, the panels transfer wind and weather loads to the structure. Canadair built and installed a curtain wall panel measuring 4.3 x 6.1 m (14 x 20 ft.) in the wall of a building at Plant 4 and alternately used the blast of a J85 jetengine and a Rolls-Royce Merlin piston engine, combined with a water spray, to test the panel's ability to withstand hurricane-force winds and extreme heat.
Canadair-manufactured curtain walls were used in a number of Montreal buildings including CIL House (later called Maison Royal Trust)(CL-92); Westmount Square; "Le Cartier" apartment building; the Montreal headquarters of the Quebec Provincial Police, and the grandstand at Blue Bonnets race track. Some 4,000 panels were used in the construction of the 34-storey CIL House. Other contracts included a facade for the Aeroquay at Toronto's Malton Airport (CL-94); a load-bearing structural steel wall for the Laval (Quebec) City Hall, and a number of components for Montreal's Place Victoria Stock Exchange Tower.
Airport Control Towers: In 1965, the division was renamed Canarch and design work began on two types of air traffic control tower cabs - the glassed-in portion of an airport control tower. Thirty-two C-1 (CL-231) cabs and six larger C-2 (CL-233) cabs were supplied to the U.S. FAA which erected them in such major airports as Chicago O'Hare, Oklahoma City, San Diego, Jacksonville and West Palm Beach.
Canadair also supplied small transportable tower cabs (CL-232) to Canada's Department of Transport for temporary airport air traffic control and to the U.S. Navy for missile-firing range control.
