Study Area 43 is located mainly in the wards of Don Valley West & Don Valley East.  It is roughly bounded by Highway 401 to the north and Wynford Drive to 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.

The City held a public event in July 2019 at Banbury Community Centre to showcase the recommended solutions in the study area and allow the public to provide feedback.

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.
