One of the pilot areas is proposed to be located within the Mandatory Downspout Disconnection zone bounded by Norfolk St. to the North, Dougall Ave/Howard Avenue to the East and the Herb Gray Parkway to the West and South. It is anticipated that the program will be ready to begin in the Spring of 2021.

While mandatory downspout disconnection has many benefits, some of the negatives include:

Once there are sufficient results to indicate the effectiveness of the Mandatory Downspout Disconnection Pilot program, the results will be communicated to Council.
