Ford Model T track
Built for the Ford Motor Company of Canada in 1914, the roof of 672 Dupont St. was once a place to burn rubber in Model Ts. Each floor of the building, from the first-floor showroom to the fifth-level paint shop, was designed specifically for housing, assembling and showcasing the cars. Two freight elevators delivered them to the reinforced roof for testing. The building still stands, but the elevators are bricked up, so no cars have been racing around the roof of late.
