In progress Environmental assessment

Cooksville Creek Erosion Control Project south of Lakeshore Road

The City of Mississauga is undertaking a Municipal Class Environmental Assessment (Class EA) Study for erosion control and restoration of Cooksville Creek south of Lakeshore Road.

This section of Cooksville Creek has been impacted by recent storm events and high lake levels and is in need of rehabilitation to address existing erosion issues.  Rehabilitation plans will also need to consider impacts to the adjacent City trail through Helen Molasy Memorial Park that sits above the east bank of the creek, as well as the neighbouring properties which have experienced ongoing drainage issues.

Project objectives

The main goal of this project is to develop a restoration design to mitigate the existing erosion problems for this section of Cooksville Creek, and provide long-term stability to the creek corridor, while also protecting or enhancing the existing environmental resources within the study area.

The City will also be looking to develop related restoration plans for the Helen Molasy Trail and berm that sits atop the eastern creek bank, as well as developing solutions to reduce or eliminate drainage problems along the neighbouring properties.


  • Provide long-term erosion protection along the creek banks
  • Increased safety and protection for nearby infrastructure and property
  • Improvements to the environmental health of the creek while enhancing aquatic habitat and vegetation
  • Opportunities for planting of native species, and enhanced wildlife habitat where possible
