The City of Toronto is undertaking a Municipal Class Environmental Assessment (EA) Study to explore opportunities to improve reliability of an aging sanitary forcemain that serves the Warren Park Sewage Pumping Station (SPS). A forcemain is a pressurized sewer pipe that transports wastewater from a lower to a higher elevation. The existing forcemain is located in Warren Park in the city of Toronto.

Study Commencement and Virtual Public Meeting #1

The Warren Park Forcemain Replacement study is following Schedule “B” of the Municipal Class Environmental Assessment (MCEA) process. The public is invited to provide input to help identify ways of reducing impacts on surrounding users, and to support the process of selecting the preferred solution. There will be two virtual Public Meetings held for this project.

A Virtual Public Meeting was held on the evening of April 28, 2022. This was an opportunity to learn more about the project, provide feedback and ask questions. A copy of the presentation materials are provided at the link below for your review and comment. Please provide any comments you may have on the presentation materials by May 12, 2022 to

The City of Toronto initiated the forcemain replacement project to build redundancy into the City’s wastewater collection system and improve aging infrastructure.

The proposed work includes the replacement of the existing forcemain with two new forcemains. The existing forcemain is approximately 550 m in length and is located along the east side of the Humber River near Baby Point Crescent, to the Warren Park SPS on Pasadena Gardens. The new forcemains are being installed to improve aging infrastructure and ensure reliability of the system. The work also includes modifications to the existing Warren Park SPS to accommodate the additional forcemain.

A variety of alternative alignments and construction methods will be considered and evaluated as part of this study.

The majority of the proposed alignment is located within the existing forcemain easement adjacent to the Humber River Recreational Trail.

Study Process

This Study follows Schedule “B” of Ontario’s Municipal Class Environmental Assessment (EA) process which promotes good environmental planning by determining and managing the potential effects of a project prior to implementation.  The EA process includes identifying the problem or opportunity to be addressed, developing and evaluating a range of alternative solutions, providing opportunities for public input, and identifying a preferred solution.

Public Consultation

Two virtual Public Meetings are planned for this study. Please refer to the News & Updates tab to review project materials and event notifications.

1. When is construction for the Warren Park Forcemain Replacement Project proposed to occur and for how long?

Construction is currently planned to begin in late 2023 or early 2024 and will last approximately five to six months. Before construction can begin, the Environmental Assessment study and the detail design must first be completed (targeting completion in mid-2023). The construction period will likely be shorter in comparison to some other projects in the area because of the open-cut replacement method that will be used.

2. Will alternative pedestrian and cyclist routes be provided during construction? Will access to Magwood Park be maintained from Pasadena Gardens and St. Mark’s Road?

Signed detour routes for pedestrians and cyclists will be provided on local roads during construction. The exact location of detour routes and the anticipated impacts to the park will be determined as part of the next phase of the environmental assessment study.

The intent of the project is to maintain access to the park at all times during the project; however, some access points may be unavailable at times during construction.

3. Is a forcemain anticipated to be constructed north of the existing pumping station, in addition to what is being proposed in this project?

The existing forcemain will be replaced with two twin forcemains south of the pumping station. No additional forcemain is needed north of the pumping station as part of this project.

4. What other construction projects are ongoing in the area? What is their status and when will they be complete?

In addition to the Warren Park Forcemain Replacement project, there are three other construction projects ongoing in the area. The following provides additional information about these projects.

Forcemain Replacement Group 1 Project – Baby Point Sewage Pumping Station

  • Progress: Minor restoration work remaining. Please see the Construction Notice issued in April 2021.
  • Completion Target: Work to be completed spring 2022.

Pumping Station Upgrades – Group 6 Project

  • Progress: Work is ongoing across all of the Sewage Pumping Station sites included in this project. Site trailers located in Magwood Park will remain until the entire project is complete by the end of 2024. The area will be restored to the original condition.
    • Warren Park Sewage Pumping Station: Work ongoing. Construction notices were distributed to homes in immediate area by Contractor.
    • Baby Point Sewage Pumping Station (Etienne Brulé Park): Work anticipated to start spring 2022 (potential to be delayed to spring 2023). Construction activity may take up space in Etienne Brulé Park parking lot.
  • Completion Target: Upgrades to all Sewage Pumping Station sites to be completed by the end of 2024.
    • Warren Park Sewage Pumping Station: Work to be completed late fall 2022.
    • Baby Point Sewage Pumping Station (Etienne Brulé Park): Construction to take 8 to 10 months.

Basement Flooding Project

  • Progress: Work ongoing. Site trailer at entrance of Etienne Brulé Park and fenced-off laydown area in Etienne Brulé Park parking lot to remain until work complete. Please see the Construction Notice issued in August 2021.
  • Completion Target: Work to be completed fall 2022.

5. When will the next virtual public meeting be held?

A second Virtual Public Meeting will be held to present the preferred solution for the forcemain twinning, including anticipated impacts and measures to mitigate impacts. Determining the preferred solution requires completion of the Stage 3 Archaeological Assessment, which is tentatively planned for the summer of 2022.  Findings from the archaeological assessment may impact the preferred solution for the forcemain alignment. As such, the next virtual public meeting is tentatively scheduled for the fall of 2022.
