User:Geo Swan/Lower Don River flood control

Toronto, Ontario has a large parcel of brownfields that requires flood control of the Lower Don River before it can be redeveloped. Shortly after the turn of the 20th century the Don River was canalized from the Bloor Street Aqueduct south to its mouth. A marsh, known as Ashbridge's Bay, was filled in, and used for industrial purposes.

The banks of the canalized portion of the river are concrete, providing no wildlife habitat.
