The City of Toronto has developed a Concept Trail Plan for Lambton Woods, a 21.6 hectare Environmentally Significant Area (ESA) located on the west side of the Humber River between James Gardens and Lambton Park. The first step in implementing the trail concept plan is the replacement of a wood pedestrian bridge (H in Trail Concept Plan Map).

Project Timeline

  • Summer 2019: trail concept plan complete
  • December 2020: pedestrian bridge detailed design complete
  • Winter 2021: tree removals in preparation of bridge installation
  • Summer 2021: construction to begin, trails to be closed during construction with detour signage posted
  • Late Summer/Early Fall 2021: construction complete, trails re-opened
  • Fall 2021: restoration planting


The City has been working for a number of years to manage natural environment trails in parks and ravines to ensure the protection of our forests and natural areas while allowing for compatible recreational uses. These trails are well used by hikers, dog-walkers, mountain bikers and natural environment enthusiasts and are highly valued as an important part of the recreational trail network. Growing demand for recreational trails is leading to unsustainable trail use, unauthorized trail creation and damage to natural areas.

Lambton Woods contains high-quality deciduous forests on steep valley slopes and portions of a narrow floodplain, as well as a large groundwater discharge area, and smaller open wetland. It provides habitat for a number of significant species, including migrating songbirds.

Construction is expected to begin in late July, and is anticipated to be complete by the end of August. During construction, the Humber Recreational Trail will remain open, however there will be intermittent disruptions between James Gardens and the Humber pedestrian bridge. Warning signs will be in place during this time.

As part of the bridge design and approvals process, a number of studies were completed to determine the required size and placement of a new bridge. The new bridge will be installed approximately 25 meters upstream where there is less projected streambank erosion. The existing trail network will be realigned to meet with the new bridge location. The bridge has been designed in sections that can be assembled onsite to minimize impacts to the surrounding forest.  A number of trees will be removed prior to construction, including a number of invasive species. Restoration planting of native species will begin following construction completion.
