In progress Environmental assessment

Carolyn Creek Erosion Control

The City of Mississauga is undertaking a Schedule B Class Environmental Assessment Study for erosion control and restoration of Carolyn Creek along Barbertown Road.

Project overview

Carolyn Creek originates in the residential area at Terry Fox Way and Blueheron Boulevard before being conveyed through the study area alongside Barbertown Road and discharging into the Credit River on the east bank.

Carolyn Creek Erosion Control Study Area

The creek currently consists of an engineered channel with bank and grade control structures composed of stone-filled gabion baskets that were installed 30 to 40 years ago over the 200 metre length of creek.

The gabion baskets are no longer functioning as intended and are resulting in the erosion of channel banks that are posing a risk to adjacent infrastructure, property and the environment.

Through the City’s ongoing erosion monitoring program, this section of Carolyn Creek has been identified as requiring rehabilitation.


The main goal of this project is to mitigate the existing erosion problems and ensure 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 infrastructure and property
  • Enhances aquatic habitat and riparian vegetation
  • Opportunities for planting of native species, and enhanced wildlife habitat where feasible

Online Public Information Centre

Consultation is an important part of the Municipal Class Environmental Assessment (MCEA) process and we want to hear from you. A Public Information Centre (PIC) presents information related to the study and allows an opportunity for residents and stakeholders to provide input. The PIC for this project was conducted online.

Through the MCEA process, the project team developed and evaluated alternative solutions for Carolyn Creek. A preliminary recommended solution was identified for public review and comment. PIC materials and a comment form were made available in spring 2022. We appreciate the input from all those who provided submissions during the consultation period.
