The Junction Tree Map rested by a effort of Leaf is still viewable. You can see where and what types of trees are in Dundas St. W. and some on the north south streets where they are close to Dundas St. W.
Leafs statement about the project.
In 2017 and 2018, LEAF and the City of Toronto collaborated with Green 13, the Junction BIA the Junction Residents’ Association and the Toronto Field Naturalists to establish an Adopt-a-Street-Tree project. With nearly 140 trees lining the Junction’s streets, the community is working to ensure the health and vibrancy of their street canopy.
