Several huge infrastructure projects along Mississauga’s lakeshore will lead to some delays and hindrances for residents and drivers, but ultimately bring about major benefits for the city, project leaders say.

Work on one particular project is already underway on a stretch of Lakeshore Road and it’ll impact public transit riders, those who walk and cycle on a popular waterfront trail and others for the next two to three years, according to Region of Peel officials.

Those in charge of the infrastructure upgrade work said two temporary construction sites — one next to the Credit River, the other a couple of kilometres to the west at Richard’s Memorial Park — will remain in place for the duration of the work.

The Richard’s Memorial Park worksite will remain in place until fall 2027 while the other is expected to be needed until fall 2028, the region said.

They’re needed, officials say, in order to complete:

  • Installation of a new watermain and large sanitary sewer along Lakeshore Road, between Jack Darling Memorial Park and Elmwood Avenue.
  • Installation of a new sanitary sewer on Wesley Avenue, from Park Street to Lakeshore Road.
  • Replacement of a section of watermain between Ibar Way and Shawnmarr Road.

The construction site at Richard’s Memorial Park is set up on the south side of Lakeshore Road West and used to access the tunnel and install the new large trunk sewer on Lakeshore Road.

Until fall 2027:

  • The bus stop at that location will be closed. An existing bus stop is available nearby, just west of Balboa Drive, officials say.
  • The Lakeshore Road West Trail (a multi-use trail to the south of Lakeshore Road) will be re-routed around the construction site while it’s in place.

The worksite by the Credit River, to be located on the east side of the boulevard on Front Street North, “will be an important working area for the project and will be used to dig tunnels and install the new large trunk sewer and watermain on Lakeshore Road,” project leaders said earlier.

Until fall 2028:

  • Marina Park North, the parking lot and the sidewalk on the east side of the roadway will all be closed due to the construction site’s presence.
  • The bus stop on the east side of Front Street North, south of High Street, will be relocated to just north of the High Street intersection.

Region officials note the above dates are approximate and may change due to weather conditions or other unexpected events.

Similar temporary construction sites will also be present at several other locations along Lakeshore Road as work progresses.

Officials added they appreciate people’s patience “as we work to improve our community’s infrastructure” as the south end of Mississauga experiences significant growth.

The Region said residents and others seeking updates on the work can attend a project open house scheduled for April 15 from 5-7 p.m. at Port Credit Royal Canadian Legion (35 Front St. N.).

Public session will tell residents what they want to know

Project leaders said they’ll be talking about the ongoing watermain and sanitary sewer project, providing an overview to those in attendance of what to expect during construction and when work is expected in various areas.

“This provides an opportunity to meet the project team and get any questions answered,” the Region said in a project update.

Officials said they’ll also share details of other upcoming projects in the area, including work on the Sewage Pumping Station in Jack Darling Memorial Park and development-driven sanitary sewer upgrades within the Hurontario Street and Lakeshore Road area.

Construction along the entire corridor is expected to continue until late 2029, the region said. In addition to other impacts, temporary lane and road closures are also to be expected.

“Peel Region is undertaking this work to meet future needs of the community while providing a reliable wastewater collection system and water supply system,” officials said in an earlier project update.

The ongoing project, according to the region, will provide:

  • Increase in water and wastewater system capacity to accommodate future growth in the Port Credit area.
  • Efficient water distribution and sewage conveyance.
  • High-quality water supply services for end users.
  • Resiliency within the sewer and water systems.
  • Opportunity to retire seven existing sewage pumping stations (Jack Darling 2, Richard’s Memorial Park, Ben Machree, Indian Road, Front Street, Elmwood, Hiawatha), thereby reducing long-term operational and maintenance costs to the region.
