Construction on Lake Shore Boulevard East

Now that the Gardiner-Logan ramps are removed, the easternmost access point to and from the Gardiner Expressway is at Jarvis Street.

The realigned Gardiner and new ramps east of Cherry Street are in design now as part of the City of Toronto’s plans to reconfigure the Gardiner Expressway. Construction on the new ramps is tentatively scheduled to start in 2026. The City of Toronto will share more information regarding ramp realignment and construction starting after the completion of this project as it becomes available.

You can find updates on the City’s Gardiner East project here.

Minimizing Construction Impacts

Port Lands Flood Protection is a seven-year construction project – and one of the largest infrastructure projects in Toronto’s history.  

During the Don Mouth Naturalization and Port Lands Flood Protection Environmental Assessment, the project team identified potential impacts from this construction and developed a series of plans to manage these impacts. Following these Environmental Management Plans will allow us to minimize impacts to the environment during and after construction. These plans may be modified to reflect new information or challenges encountered on the construction site.  

To make the details of these plans easier to find and understand, we’ve summarized each plan. Those summaries are available here: 

Air Quality and Noise Monitoring Plan 

Groundwater Management Plan

Odour Management Plan

Soil Management Plan

Surface Water Management Plan

We recognize the challenges and inconveniences construction presents to local communities. While some construction projects cannot be changed or delayed, we minimize impacts as best we can.

Here are some of the ways we’re reducing construction impacts for the Lake Shore Boulevard East project:

• Coordinating with the City of Toronto and outside agencies such as Metrolinx and Toronto Hydro to identify their construction needs and avoid overlapping road closures
• Changes to lane configuration and traffic signal timing to keep traffic moving
• Reconstruction at certain intersections and ramps to the Gardiner Expressway to improve the flow of traffic during construction

Construction Schedule

Construction on the Port Lands Flood Protection project started in 2017 and will be done in 2024. See what’s coming up over the next few months. We’ll continue to adjust our construction sequencing and timing to account for factors like nearby construction and coordination with our partners. Find out more about what we’re building.

Construction on the Lake Shore Boulevard East project started August 31, 2021. Construction will be complete in 2024.

Construction Liaison Committee (CLC)

The Port Lands Flood Protection Construction Liaison Committee (CLC) is made up of local residents and businesses. Members meet regularly with the project team to discuss construction activities and updates. The committee is tasked with bringing forward questions, concerns and feedback from the communities they represent. They work closely with the project team and construction manager, EllisDon, to ensure surrounding communities are aware of upcoming construction and help the project team manage any potential construction impacts.
