Toronto.

Toronto sits on the north shore of Lake Ontario at the western end of the lake's deepwater basin, cut by a dense ravine system that follows the Don and Humber rivers from the old Lake Iroquois shoreline down to the present-day waterfront. The Toronto Islands shelter the harbour — eighteen islands connected by bridges and pathways, car-free, a thirteen-minute ferry from the Jack Layton Ferry Terminal at Bay and Queens Quay.

The ravine network protected under the City's Ravine and Natural Feature Protection Bylaw covers roughly 17% of Toronto's land area and threads the city through Crothers Woods, Riverdale Park, the Don Valley Brick Works, Taylor Creek Park, and the Humber Marshes. The Martin Goodman Trail runs along the Lake Ontario waterfront from the Humber Bay Arch Bridge east to the Rouge River — the Toronto segment of the Great Lakes Waterfront Trail.

At the eastern edge of the city, Rouge National Urban Park is Canada's first national urban park, with the Toronto/Scarborough portion holding the Mast Trail and the only campground inside the city limits. Tommy Thompson Park on the Leslie Street Spit is a globally significant Important Bird Area.

The whole network sits within the traditional territory of the Mississaugas of the Credit, the Anishnabeg, the Chippewa, the Haudenosaunee, and the Wendat, covered by Treaty 13 (the Toronto Purchase, 1805) with the Mississaugas of the Credit.
