Sawmill Creek Erosion Control – Folkway Drive to Erin Mills Parkway

The City of Mississauga is undertaking a Schedule B Class Environmental Assessment Study for erosion control and restoration of Sawmill Creek from Folkway Drive to Erin Mills Parkway.

Project overview

Sawmill Creek flows through Greenlands Park between Folkway Drive and Erin Mills Parkway and features several pedestrian bridges over the creek that connects the Sawmill Valley Trail.

Currently, the creek is channelized with many banks and grade control structures composed of stone-filled gabion baskets that were installed 40 to 50 years ago over the 1.1 km length through the park.

The gabion baskets are no longer functioning as intended and are resulting in the erosion of channel banks and woody debris blockages that are posing a significant risk to the adjacent trail, sanitary sewer infrastructure and environment.

The City has identified this reach of Sawmill Creek as a high priority site in need of rehabilitation.

The main goal of this project is to mitigate the existing erosion problems and ensure long-term stability of the creek using natural design techniques, where feasible, while also protecting or enhancing the existing natural environment within the study area.


  • Improves the stability and environmental health of the watercourse
  • Maintains or improves the hydraulic capacity of the creek, and protects nearby trails and infrastructure
  • Enhances aquatic habitat and riparian vegetation
  • Opportunities for planting of native species, and enhanced wildlife habitat where feasible
