Dixie-Dundas Flood Mitigation Project


• The lands south of Little Etobicoke Creek surrounding Dixie Road, referred to as “Dixie-Dundas” for this project, are subject to flooding as a result of spilling from the creek during high flow conditions. This urban area consists of a variety of commercial, industrial, residential, and park land uses.
• The study area of the Schedule ‘C’ Municipal Class Environmental Assessment (EA) has been expanded downstream to the Canadian Pacific (CP) railway crossing. This expanded study area includes the Dundas Street East crossing.
• Recent hydraulic modelling indicated that expansion of the study area to include the Dundas Street East crossing and downstream areas is required to seek flood mitigation solutions for the Dixie-Dundas area.



• The City of Mississauga has an interest to protect flood-vulnerable residences and businesses as well as to intensify Dixie-Dundas to fulfill the vision of growth expressed in the Dundas Connects Master Plan.

• Alternative conceptual solutions for the expanded study area are currently being developed. The alternative solutions for the initial study area are presented on the project website below.
• In consultation with the public and agencies, the EA will evaluate these alternative solutions to identify preferred alternatives for both the initial and expanded study area. The preferred alternatives will then be advanced to preliminary design.
• The preferred solution will mitigate the risks of flooding, to the extent possible, to people, property, and infrastructure.
• At the end of the EA, a report documenting the process will be available for public review.

• Consultation is an essential part of the EA process. We want to ensure that anyone with an interest in the study has the opportunity to provide input as the study proceeds.
• Online public engagement is a part of the project to allow local residents and interested members of the public an opportunity to review project information and provide input for the study area.
• As the study progresses, a project bulletin presenting the alternative solutions for the expanded study area will be made available through the project website. Notification will be provided when this project bulletin is available for review and input.
