BF43 study area map

Study Area 43 is located mainly in Ward 15, Don Valley West & Ward 16, Don Valley East.  It is roughly bounded by Highway 401 in the north and Wynford Drive in the south, and between Yonge Street and Don Mills Road. The Study Area is serviced by a separate storm and sanitary sewer system and has a natural watercourse Wilket Creek that flows through the study area from north to south.

In July 2019, a public event was held at Banbury Community Centre to review, discuss and provide public feedback on the recommended solutions to reduce the risk of future area flooding and improving stormwater runoff quality in the study area.

What is a Class Environmental Assessment?

Ontario’s Environmental Assessment (EA) program promotes good environmental planning by determining and managing the potential effects of a project prior to implementation.

The EA program ensures that public concerns are heard. EA balances economic, social, cultural and natural environmental needs so that projects benefit Ontario.

This study is being carried out according to the Municipal Class Environmental Assessment process. This is an approved approach to satisfying requirements of the Environmental Assessment Act specifically tailored to municipal infrastructure. The process includes identifying the problem or opportunity to be addressed, developing and evaluating a range of alternative solutions, providing opportunities for public input and identifying a preferred solution.
