Currently, about 290 hectares (715 acres) of southeastern downtown are at risk of flooding from the Don River watershed. This includes parts of the Port Lands, South Riverdale, Leslieville, south of Eastern Avenue and the East Harbour development site. Port Lands Flood Protection is a solution to flood protect these lands and enable the transformation of the underused Port Lands into a place where people can live, work and play, while still preserving some industrial uses.This project involves excavating a new river valley and a creating a naturalized mouth for the Don River in the Port Lands. The project also includes new parks, aquatic habitat and infrastructure such as roads, bridges, utilities and transit infrastructure to support future development. The project includes:

  • Resilient, green infrastructure
  • A new river valley that has the capacity to handle large volumes of flood water
  • The Don Greenway that provides excess capacity to convey flood water through the existing Shipping Channel
  • New roads and bridges
  • Structures to control water flow and manage sediment and debris

Waterfront Toronto received $1.25 billion in funding from the City of Toronto, Province of Ontario and Government of Canada to design and build the Port Lands Flood Protection Project.

In 2016, we completed a 15-month Due Diligence study that resulted in dozens of critical reports totaling over 10,000 pages. We did this to make sure our plan to flood protect and revitalize the Port Lands could work – and that includes the cost. The amount includes a contingency of 30 per cent and accounts for the projected cost of inflation throughout the project timeline.  

290 hectares of land are at risk due to flooding from the Don River, under a Hurricane-Hazel-sized storm event.

This image shows the area of the eastern waterfront that is at risk of flooding:

This project will remove the flood risk to 240 hectares of land. The majority of the remaining 50 hectares of land will be intentionally designed to flood, and they are located within the Keating Channel and the new naturalized river valley system.

Construction began on the Cherry Street Lakefilling Project in December 2017. We plan to start digging the new river valley in summer 2018. The Port Lands Flood Protection Project is scheduled for completion in 2023, with public access to new spaces in 2024.

Hydraulic modelling done by Toronto and Region Conservation shows lake levels will not impact flood levels from the Don River. Higher levels may inform our approach as we design ecological components of this project, as well as bridges and pathways.  

Water levels in Lake Ontario typically fluctuate by up to one metre above and below average lake levels. We’re designing wetlands that can survive extremes of high or low water levels. The wetlands will be built at different elevations, which means if water levels go up or down, there will always be some areas available for fish, birds and other wildlife to find food and shelter. This keeps the entire system healthy.   

In the event of prolonged extreme weather or lack of water due to low lake levels, a monitoring plan will be in place so that we can adapt the system.   

The naturalized areas already exist in the Port Lands are staying untouched. Spaces like Tommy Thompson Park and Cherry Beach aren’t within this project area – they’re important habitat for wildlife and natural spaces for people to explore. You can see the area of the Port Lands we’re transforming on the project map located here.

The new river valley will create Villiers Island. However, this project doesn’t include the development of new buildings on Villiers Island, or anywhere in the Port Lands. That development can begin once Port Lands Flood Protection is complete in 2023.

The guidelines for buildings, roads and more on Villiers Island are in the Villiers Island Precinct Plan. The Villiers Island Precinct Plan was adopted by Toronto City Council in October 2017, along with the Port Lands Planning Framework, which sets the long-term vision for the Port Lands. As part of the planning process to finalize the Villiers Island Precinct Plan, we collaborated with the City of Toronto to consult the public. Find public presentations and meeting summary reports in our document library.

The design work underway does consider parks, public spaces and roads on Villiers Island to make sure what we build as part of Port Lands Flood Protection works as part of the larger, future system of parks in the Port Lands. It doesn’t deal with any new buildings. Find out more about what we are building as part of Port Lands Flood Protection here.

The approach for this project was set through the Don Mouth Naturalization and Port Lands Flood Protection Environmental Assessment (EA). That EA was approved by the Province of Ontario in 2015 – it won’t change. You can find more details here about what we’re building as part of Port Lands Flood Protection. We’ve now started construction on this project and it is scheduled to be complete in 2024. Find more details about our construction schedule here.

Waterfront Toronto and Sidewalk Labs are partnering to create a new kind of community on Toronto’s waterfront at Quayside, 12 acres of land situated along Toronto’s waterfront at the intersection of Lake Shore Boulevard East and Parliament Street

Waterfront Toronto recently finalized an agreement with Sidewalk Labs that outlines how planning for Quayside will move forward. You can find more details about that agreement here.

Once we complete construction on the Port Lands Flood Protection project in 2023, a new river valley will run through the Port Lands. This natural landscape will become home to diverse plants and wildlife. Land that was once unusable and under the threat of flooding will be ready to transform into complete communities and thriving businesses.

Any development that takes place will be guided by the Port Lands Planning Framework, approved by Toronto City Council in 2017.

Planning initiatives for the Port Lands have been underway for over a decade, and have resulted in not only the Planning Framework, but a number of other key studies and plans that will guide development. Read more about those plans here.
