Notice of Public Information Centre – Master Plan
2025 Water and Wastewater Master Plan for the Lake-Based System
How is this Study being Undertaken?
Background
Peel Region is completing the 2025 Water and Wastewater Master Plan for Lake-Based Systems (where Lake Ontario is the source of drinking water and the discharge point for treated wastewater). The 2025 Lake-Based Master Plan will provide an update to the previous 2020 Water and Wastewater Master Plan. The study area includes the City of Mississauga, the City of Brampton and parts of the Town of Caledon as shown in Fig.1.
Process
The study will be carried out in accordance with the Municipal Class Environment Assessment (MCEA) master planning process and will involve Phase 1 and Phase 2 of the MCEA process.
The objective of the Master Plan study are to:
- Determine a preferred lake-based water and wastewater servicing strategy to address current servicing needs and accelerated growth driven by the Province’s Bill 23.
- Align with the latest Council approved population and employment forecasts to 2051.
- Assess potential growth post-2051 to inform long-term infrastructure planning.
Provide the business case for the need, timing and costs associated with servicing and infrastructure.
How Can I Participate in this Study?
Your Input is Important
Consultation and engagement with interested stakeholders, Indigenous Communities, and right holders is a key component of this Master Plan Study. One Public Information Centre (PIC) will be held to share the study process, its findings, outline the water and wastewater servicing strategies and present the preferred solution. The PIC will also provide an opportunity for participants to offer feedback to the project team.
The PIC will take place in person within each municipality, with information presented on display boards and staff available to answer questions and discuss next steps. Details for the PIC are provided below.
Information will also be available on the project website starting December 2, 2025.
