Construction on Lake Shore Boulevard East and Gardiner Expressway

The Gardiner on/off ramps to Logan Avenue are being permanently removed. Ramp removal is scheduled for September-October 2021.

Once the Logan ramps are removed, the most eastern access point to and from the Gardiner Expressway will be at Jarvis Street. In the long-term, new ramps are planned at Cherry Street as part of the City of Toronto’s Gardiner East project.

Starting in October 2021, there will be lane restrictions on Lake Shore Boulevard East. We will maintain two lanes eastbound and one lane westbound on Lake Shore Boulevard between Cherry Street and Carlaw Avenue. This is to accommodate reconstruction of the Lake Shore Bridge over the Don River and Lake Shore Boulevard East from Don Roadway to Carlaw. Construction will be complete in 2024.

Please note these dates are anticipated based on current information, and subject to change due to changes in construction schedule, weather, or unforeseen circumstances.


  • The Gardiner ramps to/from Logan Avenue are now permanently closed.
  • On weekends from September-October 2021, Lake Shore Boulevard East will be closed from Cherry Street to Carlaw Avenue (9p.m. Friday-6a.m. Monday). Closures will begin at 9 p.m. on Friday evenings. Lake Shore Boulevard will reopen at 6 a.m. on Mondays. For a map showing available routes, click here
  • On weekends in September, Don Roadway will be closed between the Don Valley Parkway (DVP) and Commissioners Street. There will be no access to the DVP via Don Roadway during the weekend closures.
  • As of October 1, 2021, Don Roadway will be closed from Lake Shore Boulevard to Commissioners Street on weekdays and weekends.
  • Ramp removal involves concrete breaking/crushing. This type of work will happen only on weekends between the hours of 7 a.m. and 11 p.m. See Managing Construction Impacts for more details on noise and dust.

Full closure of Don Roadway south of Lake Shore Boulevard

Starting October 2021

To begin work on the flood protection landform along Don Roadway, Don Roadway will be fully closed south of Lake Shore Boulevard, on both weekends and weekdays.


  • Traffic accessing the Don Valley Parkway northbound from the Port Lands will no longer be able to turn on to Don Roadway from Villiers Street.
  • Instead, they should continue to Saulter Street, along Commissioners Street, and go north on Carlaw Avenue to access Lake Shore Boulevard westbound and turn right on to the Don Roadway/DVP.

Lower Don Trail Closures and Detours

On weekends, the Lower Don Trail will be closed on weekends from where it crosses the Don River at Lake Shore Boulevard to Booth Avenue.

During weekdays until the end of October, 2021, the Lower Don Trail over the Don River and the cycling facility on Lake Shore Boulevard will be open. The Lower Don Trail pedestrian bridge will be closed at 9:00 pm on Friday evenings and reopen 6:00 am on Monday mornings. The section of Lower Don Trail running south of Wilson Yard will be closed as of November 2021.


  • Cyclists travelling south on the Lower Don Trail from Corktown Common will be directed to continue west along the trail that runs south of the Wilson Train Yard and connects to Cherry Street.
  • Cyclists wishing to cross the Don River will be directed to either the Martin Goodman Trail continuing to Cherry Beach, or the temporary detour with enhanced cycling facilities on Cherry Street, Villiers Street, Saulter Street, Commissioners Street and Carlaw Avenue.
  • Cyclists travelling south along Logan Avenue can take Lake Shore Boulevard east to Carlaw Avenue, take that new detour route south ending at Cherry Street which reconnects to the Martin Goodman Trail and continues west.



  • The Lower Don Trail over the Don River will be open Monday to Friday. Cyclists wishing to travel east-west will have access to Lake Shore Boulevard during this time.

Lane Diversions at Cherry Street and Lake Shore Boulevard East Intersection: August – October 2021

Starting in August, changes to the north section of the intersection of Cherry Street and Lake Shore Boulevard will begin.  Traffic travelling south on Cherry Street towards Lake Shore Boulevard will not be able to turn left to go eastbound on Lake Shore Boulevard. Eastbound Lake Shore Boulevard traffic will be restricted to one lane.

Reconfiguring the intersection of Cherry Street and Lake Shore is necessary to:

  • Integrate with the future Cherry Street, which will be rebuilt further west of existing Cherry Street
  • Connect a new watermain to the Port Lands and install new traffic signals and street lighting
  • Improve the intersection for pedestrians and cyclists



  • Southbound traffic on Cherry St. will be forced onto Lake Shore Boulevard westbound
  • Eastbound traffic on Lake Shore Boulevard will be reduced to a single lane
  • Construction noise and dust


Above: This map shows the location of the intersection improvements.

Lane Restrictions on the Martin Goodman Trail, Until November 2021

Continue to expect intermittent lane closures on the Martin Goodman Trail between Parliament Street and Cherry Street. One lane will always remain open. Signs and flagpersons will direct east-west pedestrian and cyclist traffic. Whenever it is safe, priority will be given to  pedestrians and cyclists. As the work progresses, the path will be cleaned and patch-paved for safety. These closures are needed as we finish work on utilities beneath the new Cherry Street.


  • Lane restriction: The Martin Goodman Trail will be reduced to a single lane only for periods of 1-2 days at a time
  • Closures will shift between eastbound and westbound lanes
  • Delays: Cyclists and pedestrians will be prioritized when safe, but expect some wait time
  • Construction noise and dust

Above: This map shows the section of the Martin Goodman Trail (MGT) where closures will occur between March-November 2021, and the location of signage and flagpersons.   



Commissioners Street remains closed between Cherry Street and Don Roadway. Don Roadway remains closed between Commissioners Street and Villiers Street. Both closures will remain in place until Summer 2022.

Minimizing Construction Impacts

To create a new, kilometre-long river valley, renaturalized river mouth and spillway, we’ll excavate 1.4 million cubic metres of soil — that’s enough to fill the Rogers Centre. We plan on reusing as much of this soil as possible on site. We’ll also rebuild sections of the Don Roadway, Cherry and Commissioners Street and remove portions of Villiers Street. And we’ll raise grades on the new Villiers Island and east of the Don Roadway by one to three metres. 

This 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. The team has now 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. As construction progresses, 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

Removing the on/off ramps from the Gardiner Expressway to Lake Shore/Logan Avenue will involve heavy concrete breaking, jackhammering and crushing. This noise-generating work will take place from 7 a.m. to 11 p.m. on Saturdays and Sundays in September and October 2021.

Here’s how we will manage noise, vibration and dust:

• At the beginning and end of each shift, equipment operators will clean, lubricate and inspect machines to help reduce noise.
• All construction equipment on-site will have an exhaust muffler to suppress sound.
• Reverse beacons ensure worker safety. Every effort will be made to secure and use equipment with lower volume devices to minimize beeping noise.
• Any work outside of 7 a.m. – 11 p.m. will be limited to clean-up of the Gardiner concrete sections, steel beam removal, and general non-crushing activities and other low-noise-production work.
• Crews will use water trucks to control dust and mud.

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. Watch this video showing the current construction schedule. Find out more about what we’re building.

Construction on the Lake Shore Boulevard East project starts August 31, 2021, at 9 p.m. with the removal of the physical Gardiner ramps to Logan Avenue. Concrete breaking/crushing work will happen only on weekends between the hours of 7 a.m.-11 p.m.  This is scheduled for completion in October 2021. Work will then start on Lake Shore Boulevard in November 2021. Lake Shore Boulevard East is not expected to close again once the Gardiner ramps are removed. Construction will be complete in 2024. Find road and detour maps to help you get around during construction.

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.
