The cancelled expressways in Toronto were a planned series of expressways in Toronto, Ontario, Canada that were only partially built or cancelled due to public opposition. The system of expressways was intended to spur or handle growth in the suburbs of Toronto, but were opposed by citizens within the City of Toronto proper, citing the demolition of homes and park lands, air pollution, noise and the high cost of construction. The Spadina Expressway, planned since the 1940s, was cancelled in 1971 after being only partially constructed. After the Spadina cancellation, other expressway plans, intended to create a `ring` around the central core, were abandoned.
