Notice of study commencement – March 19, 2026

Project background

Peel Region continues to grow, and new infrastructure is needed to ensure residents and businesses in Caledon have reliable access to clean drinking water now and in the future. To support this, Peel Region is undertaking a planning study for new water infrastructure in the Bolton area., the Bolton Zone 7 Water Elevated Storage and Transmission Mains Schedule ‘C’ Municipal Class Environmental Assessment (MCEA).

This study will examine the need for two new water towers for storage and the large underground water pipes that connect them to the existing system. This planning work is being completed through a MCEA which is a provincially regulated process that helps identify the best solution while considering the environment, technical requirements, costs, and community input.

The study forms part of Peel’s Flow South Caledon Program, a new program-based approach that groups multiple water and wastewater projects within a broader geographic area to efficiently support growth in southern Caledon. It builds on previous planning work completed under the Bolton Water and Wastewater Capacity Improvements Schedule ‘C’ study, and incorporates updated growth forecasts to the year 2051, developed with local municipalities, and considers new provincial housing targets introduced through Bill 23.

As part of this study, Peel Region will confirm how future water service should be provided in Bolton, including areas that will rely on new water pressure zones – specifically Pressure Zones 7B and 7E. Pressure zones are a standard water system planning tool used to manage water pressure across different elevations and neighbourhoods, and they do not affect drinking water quality. The study area is shown in Figure 1.

Municipal Class EA process

This study will follow the 2024 process for a Schedule ‘C’ MCEA project, which includes:

• Meaningful Indigenous Community engagement.
• Public and interested stakeholder consultation and engagement.
• Identification of projects that may be exempt from the MCEA process (as per the recent 2024 amendment) through the Archaeological Screening Process (ASP).
• Development, evaluation, and selection of two elevated tank locations, including water route options, impact assessment and mitigation measures.
• Development, evaluation, and selection of the preferred water construction methodology, including shaft locations.

Your input is important

Three (3) Public Information Centers (PICs) will be held at key points during the study to present findings from the MCEA study and provide opportunities to give feedback to the project team. The first PIC is anticipated in late spring 2026 to present the identified problems or opportunities, the existing conditions and constraints, and an overview of the study process. The second PIC will present alternative solutions, evaluation findings, and the preliminary preferred tank locations with water servicing strategies. The third and final PIC will present the preliminary preferred design concept for the preferred tank locations and overall water strategy.

Once the study is complete, the MCEA Report which documents the full study process will be available for public review and comments.
