South of Pottery Road it enters a more degraded section and ends up in a straightened section that includes cement and steel dock wall, a remnant from an earlier industrial era. The river flows from there into the Keating Channel at Lake Shore Boulevard East which is at the north east corner of the Toronto Harbour. The western section of Taylor-Massey Creek and the southern portion of the western branch are surrounded by parkland (see also: "Toronto ravine system"). In more recent years the retreat of the industrial plants and rail infrastructure has freed up room which is now being turned into bicycling trails, which now extend from the shore of Lake Ontario northward in several directions to provide some 30 km of off-road paved trails. While Toronto is fairly flat in general, local cyclists have developed a number of technically challenging singletrack trails throughout the area, following the main trails.
