York Region Sewage Works Project Update

The Regional Municipalities of York and Durham are working together to carry out the York Region Sewage Works Project, a long-term wastewater infrastructure project across the Towns of East Gwillimbury, Newmarket, Aurora, Ajax and the Cities of Markham, Richmond Hill, and Pickering.

As required by the Supporting Growth and Housing in York and Durham Regions Act, 2022, the York Region Sewage Works Project will improve the existing York Durham Sewage System, by adding new or expanded wastewater sewers, pumping stations and enhancements to the Duffin Creek Water Pollution Control Plant on the shore of Lake Ontario in the City of Pickering. Durham Region supports proposed work in the City of Pickering as part of the project. 

The Act requires York Region and Durham Region to prepare a Project Report outlining infrastructure components, costs, impacts to the environment and Aboriginal and treaty rights, and how those impacts will be mitigated. On November 6, 2023, the York Region Sewage Works Project Report was posted on both York Region and Durham Region’s websites for review and comment. 

Comments received were considered by York Region and Durham Region and the Ministry of the Environment, Conservation and Parks. The revised Project Report was submitted to the Ministry for approval on March 15, 2024, in accordance with the Act. 

Following Ministry review, the Minister of the Environment, Conservation and Parks issued a letter on April 22, 2024, expressing satisfaction with the Project Report and Indigenous Communities and Interested Persons Consultation Reports. Per the letter, the project has been allowed to advance to implementation subject to continuing ongoing dialogue with the Ministry and engagement with impacted and interested Indigenous communities, along with project progress reporting. 

The final Project Report is publicly available at york.ca/SewageProject
