In progress Environmental assessment

Credit River Erosion Control from Dundas Street West to Highway 403

The City's undertaking a Schedule B Class Environmental Assessment Study for erosion control and restoration of the Credit River and Culham Trail from Dundas Street West to Highway 403.


The Credit River originates in the headwaters of the Niagara Escarpment near Orangeville and Caledon, and empties into Lake Ontario in Mississauga. The Credit River is approximately 90 kilometres long with a watershed that encompasses 1,000 square kilometres.

Credit River Erosion Control study area

The study area consists primarily of a natural river with segments providing protection for the adjacent Culham Trail by means of armourstone banks, rock vane features and gabion baskets. These erosion protection measures were originally constructed approximately 20 to 30 years ago with repairs completed over the years for certain areas.

This section of the Credit River and Culham Trail are in need of rehabilitation to remediate existing river erosion, risk to property and infrastructure and improve safety. Some of the impacts include segments of failed river bank protection, washouts and damage to the trail, valley wall erosion and ice control.


The main goal of this project is to develop a restoration design for the Credit River which mitigates existing erosion problems and provides long-term stability to the river corridor.


  • Provides long-term erosion protection along the river banks
  • Opportunities to enhance trail infrastructure while mitigating flooding and wash outs
  • Improvements to ice control and storage
  • Increases safety and protects nearby infrastructure and property
  • Improves the environmental health of the river while enhancing aquatic habitat and vegetation
  • Opportunities for planting of native species, and enhanced wildlife habitat where feasible

Public engagement

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.

Through the MCEA process, the project team has developed and evaluated alternative solutions for the project. A preliminary recommended solution has been identified for public review and comment. PIC materials and a comment form are available below. Please provide your input and/or submit your comment form by July 14, 2023.

If you have questions or comments, require further information, or would like to be added to the study mailing list to receive future notifications, please contact: Anthony DiGiandomenico at
