The Spadina Expressway was a proposed north-south freeway in Toronto, Ontario, Canada. It was only partially built before being cancelled in 1971 due to public opposition. It was proposed in the mid-1960s as part of a network of freeways for Metropolitan Toronto. Its cancellation prompted the cancellation of the rest of the network. The completed section is known today as Allen Road.
