On a Wednesday afternoon I ventured out to the farthest ends of east Toronto. Close to the Toronto Zoo is the world-renowned Rouge Park. The Rouge Park is the only national (soon) park situated within an urban centre.
Rouge Park is over 40 km2, protecting two National Historic Sites and a variety of ecosystems joining the post-glacial Oak Ridges Moraine, roughly 50 km north of Toronto, and the City’s biggest wetland, where the Rouge River empties into Lake Ontario (Source)
