Welcome to the West Main Street Area Infrastructure Improvements - Phase 2 project page. This page will provide residents, homeowners, business owners, and visitors with an overview of the construction work, additional resources, and the opportunity to connect with the project team.

Scope of work

This project is taking place on West Main Street between Prince Charles Drive and the west limits of the Main Street bridge, as well as Denistoun Street (north of West Main Street), and includes the following work:

• City’s replacement of the watermain and sanitary sewers, including laterals and services with new cleanouts and curb boxes at the property line on both West Main Street and Denistoun Street (north of West Main Street) and installation of a new Regional sanitary trunk sewer on West Main Street.
• Road reconstruction with new road granular base, base and top asphalt, and curbs and sidewalks on both West Main Street and Denistoun Street (north of West Main Street only), including new Regional storm sewers, signalization, illumination, and streetscaping on West Main Street.

Traffic disruptions

Some lanes will need to close while crews install underground utilities. At times, entire blocks may be closed to allow for this work. If a driveway needs to be closed, the contractor will let the affected property owners know ahead of time.

There will also be road closures along West Main Street for certain parts of the construction. Detour routes and signs will be posted to help guide drivers.

East Main Street bridge will be closed on November 26 to facilitate the new watermain installation. Detours have been posted and the intersection of Niagara Street and West Main Street will remain open.

Water shutdowns

If there’s an unexpected emergency water shutdown, we’ll do our best to let you know, but it might not always be possible. If your water looks brown or discoloured, let it run until it’s clear. If it still looks discoloured after running for more than 20 minutes, please call the City’s water department at 905-735-1700 x3000.

Construction update

Work is underway and crews from Beam are now on site and have started construction work on West Main Street. This first phase includes watermain installation — an important part of renewing the underground infrastructure that keeps our city running smoothly.

Construction will continue through the end of the year, with some traffic and pedestrian disruptions expected. Detours for through traffic and block-by-block closures are planned to begin in early 2026 and continue into the summer.
