The City of Toronto has initiated a study to identify sewer and watermain infrastructure in Yellow Creek that is at risk of erosion from high flows due to storms and snow melt runoff. This study will follow the Municipal Class Environmental Assessment Master Plan process.
As you walk through Yellow Creek, we ask you to share photos at two public monitoring locations. Your photos will help us track erosion and flow changes that may impact sewer and watermain infrastructure in Yellow Creek.
Please see the Notice of Commencement. To receive project updates and receive notification for the first public meeting, register your email address with yellowcreek@toronto.ca
Two public monitoring locations in Yellow Creek will be tracked during this study. We invite residents to help us track the changes at these locations by sharing your photos with us.
Your photos may be used by the study team to inform the study to better understand the conditions in Yellow Creek.
There are two ways to submit your photos:
We are monitoring the impacts of high flows at this location and the erosion which is occurring on the east bank of the creek. If the concrete area is submerged, take photos from the trail boardwalk under the bridge on the west side of the creek.
We are monitoring the impacts of high flows upstream and downstream of the pedestrian bridge.
Information will be collected in accordance with the Municipal Freedom of Information and Protection of Privacy Act. With the exception of personal information, all comments will become part of the public record. Questions about the collection of personal information may be addressed to the contact person.

Notice of Commencement (January 5, 2021)
Notice of Site Work (April 8, 2020)
During storm events, rain water or snow melt runoff enters underground pipes via drains and catchbasins on streets and in parks and is discharged from storm sewer outfalls into the watercourses that flow to Lake Ontario. At times these flows can be high, resulting in erosion damage. High flows from past storms have caused substantial erosion damage to sewers and watermains located in and near the City’s ravines and watercourses. This erosion damage can include:
This study will investigate an analyse the stream processes and current conditions impacting the storm sewer and watermain infrastructure within the ravine and undertake forecasting work to help predict future scenarios and/or impacts. Solutions can then be developed to help mitigate or prevent those future scenarios and ensure local storm sewers and watermains in Yellow Creek can continue to operate and service residents and businesses.
The Municipal Class Environmental Assessment is an approved planning process under the Ontario Environmental Assessment Act. This study will carry out the following key steps:
Public participation is an important part of this study. There are two key opportunities for public input and feedback in the study schedule:
In addition, at the last stage of this study, a final report will be produced for a 30 day period of public review and comment. We welcome your feedback at public events, by phone, mail or email. To receive project updates, register your email address with yellowcreek@toronto.ca
A Master Plan is a long range plan that examines the needs within a geographic area and provides a framework and vision to implement recommended improvements.
The study will follow the Municipal Class Environmental Assessment study process, an approved planning process under the Ontario Environmental Assessment Act, which includes providing opportunities for public input at key stages. A study report will be prepared at the end of the process.
The study will not examine trail conditions or recommend improvements to trails, forestry or ravine amenities. The City will undertake separate efforts in the future to address these features.
