Just months after a new portion of Toronto's Don River started flowing in the Port Lands, another stretch of the waterway is about to be shut down to the public for over two years. Metrolinx has announced that a portion of the Don River passing through E.T. Seton Park will be closed off to the public starting on May 20, 2025, and will remain inaccessible to watercraft until September 15, 2027. However, the valley slopes have proven an unstable work area and Metrolinx is now taking measures "to address slope instability and erosion within the work area." "To accommodate in-water works, an area of the Don River adjacent to the West Don Crossing work area will become restricted to river users," reads the Metrolinx notice.
