01 — Abstract

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.

Hiking

The Mast Trail in Rouge National Urban Park runs 2.5 kilometres one way along the historic White Pine masting route through the Toronto/Scarborough portion of Canada's first national urban park, joined by the Vista, Cedar, Orchard, Glen Eagles Vista, and Woodland trails. In the west end, the Spring Creek and Western Ravine nature trails thread the High Park Black Oak Savannah — a roughly 23-hectare remnant of a globally rare ecosystem. The Don Valley network strings Crothers Woods, Riverdale Park, the Don Valley Brick Works, and Taylor Creek Park along the Lower Don Trail; the Beltline Trail follows a former CPR rail corridor through midtown for about 9 km.

Walking & Strolling

The Toronto Islands — eighteen islands connected by bridges and pathways, roughly 5 km end to end, with a 1.5 km year-round boardwalk — sit a thirteen-minute ferry from the Jack Layton Ferry Terminal at the foot of Bay Street. The Beaches Boardwalk runs 3.5 km from Ashbridges Bay east through Woodbine, Kew-Balmy, and Silver Birch beaches past the R.C. Harris Water Treatment Plant. Tommy Thompson Park's 5 km paved access road into the Leslie Street Spit is open weekends, holidays, and weekday evenings. High Park's paved paths thread Hillside Gardens, the Children's Garden, the Maple Leaf Gardens, the Japanese Garden, and Colborne Lodge.

Nature & Discovery

Tommy Thompson Park on the Leslie Street Spit holds Important Bird Area designation ON-02 (declared globally significant in 2001), with colonial waterbird colonies of Ring-billed Gulls, Black-crowned Night-Herons, and Common Terns plus a major spring and fall passerine migration stopover; the Tommy Thompson Park Bird Research Station has operated banding programmes there for decades. High Park's roughly 23-hectare Black Oak Savannah surrounds Grenadier Pond, designated a Provincially Significant Wetland Complex in 2022. The Humber Marshes anchor the Lower Humber's river-mouth waterfowl stopover, and Rouge National Urban Park supports more than 1,700 species across its trail and habitat network.

Cycling

The Martin Goodman Trail runs along the Lake Ontario waterfront from the Humber Bay Arch Bridge east to the Rouge River as the Toronto segment of the Great Lakes Waterfront Trail. The Lower Don Trail forms a 4.7 km paved spine from Pottery Road to Corktown Commons and ties into the Pan Am Path — the city-spanning multi-use route stitching the Humber, the Don, and the waterfront into one continuous east–west and north–south backbone. The Beltline runs the midtown ravines on a former CPR right-of-way, and the Toronto Islands offer a paved car-free network reachable by ferry.

Paddling — Flatwater

The Toronto Islands inner lagoons — the sheltered network between Centre Island, Ward's Island, and Algonquin Island — give car-free flatwater paddling minutes from downtown by ferry. The Lower Humber River carries roughly 6 km of flatwater between the Old Mill area and Lake Ontario through the Humber Marshes, one of the major Lake Ontario river-mouth wetlands. On the west end, the Humber Bay Park boat launch at 225 Humber Bay Park Road West provides free public access to sheltered Humber Bay paddling between the Humber River mouth and the Lake Ontario waterfront. Open-lake conditions outside the islands are wind-exposed.

Freshwater Fishing

The Toronto waterfront falls within Fisheries Management Zone 20, with year-round Atlantic salmon (must exceed 63 cm), the standard Great Lakes calendar for bass and walleye, and lake trout open January through September plus December. The Lower Humber River carries a fall and winter chinook salmon, brown trout, and steelhead migratory run with year-round angler access from Eglinton Avenue south to Lake Ontario — one of the few in-city Lake Ontario tributaries with a sustained migratory salmonid fishery. Inner Harbour shoreline access supports warmwater bass, walleye, and perch fishing from the city's piers.

Wildlife Viewing

Tommy Thompson Park's IBA holds approximately 55,000 breeding pairs of Ring-billed Gulls — roughly 6% of the world population — alongside colonial nesting Black-crowned Night-Herons and Common Terns. The Tommy Thompson Park Bird Research Station bands migrant raptors and passerines through the spring and fall windows. The Lower Humber River's fall and winter chinook salmon and steelhead runs are visible from the same year-round-access corridor between Eglinton Avenue and Lake Ontario that the fishery uses. Rouge National Urban Park supports 261 bird species and 65 fish species across its Toronto/Scarborough trail network.

Indigenous Experiences

The High Park Black Oak Savannah is a roughly 4,000-year-old ecosystem historically maintained by Indigenous cultural burning; prescribed burns continue today as part of the City's High Park natural-area programming, drawing on Indigenous fire-stewardship knowledge. Rouge National Urban Park works with a First Nations Advisory Circle representing ten First Nations with historic and present-day connections to the park. Toronto sits within the traditional territory of the Mississaugas of the Credit, the Anishnabeg, the Chippewa, the Haudenosaunee, and the Wendat, and is covered by Treaty 13 (the Toronto Purchase, 1805) with the Mississaugas of the Credit.
