01 — Abstract

South Stormont is the riverfront SDG township between Cornwall and South Dundas, where the upper St. Lawrence widens into Lake St.

Lawrence and the Long Sault Parkway threads an 11-island chain across the pool created when the river was flooded for Seaway construction in 1958. The St.

Lawrence Parks Commission manages the parkway end to end, with Mille Roches Campground at the Long Sault end, Woodlands Campground at the Ingleside end, and three designated day-use swim beaches — Mille Roches, McLaren, and Woodlands — along the way. The Great Lakes Waterfront Trail runs the parkway and continues through Long Sault and Ingleside, connecting South Stormont's cycling and walking corridor to Cornwall to the east and to South Dundas to the west.

At Ault Park in Long Sault, the Lost Villages Museum interprets the ten communities relocated or flooded by the Seaway construction — Aultsville, Farran's Point, Dickinson's Landing, Wales, Moulinette, Mille Roches, Maple Grove, Santa Cruz, Woodlands, and Sheik's Island — and the parkway islands themselves carry the relocation story as direct artifact. The federal Upper Canada Migratory Bird Sanctuary sits in adjacent South Dundas, not in South Stormont.

South Stormont sits on the traditional territory of the Haudenosaunee and Anishinaabe Nations.

Camping

Two St. Lawrence Parks Commission campgrounds sit on the Long Sault Parkway: Mille Roches Campground at the Long Sault end and Woodlands Campground at the Ingleside end, both reserved through the SLPC reservation system. Each site is on or near the Lake St. Lawrence shoreline, with parkway swim beaches and boat launches a short drive within the chain. The campgrounds operate seasonally and pair directly with the parkway day-use system — through-driving the parkway requires a valid vehicle pass.

Cycling

The Long Sault Parkway is the cycling anchor — 11 islands threaded by paved parkway with shoreline views, designated as part of the Great Lakes Waterfront Trail. The parkway connects to the broader Waterfront Trail corridor through Ingleside and Long Sault and out to Cornwall, so day-rides can run end-to-end on a continuous route or loop the parkway as an out-and-back. Riding shares the parkway road surface with seasonal vehicle traffic; the surface is paved and the gradients are flat.

Paddling — Flatwater

Lake St. Lawrence between the Long Sault Parkway islands is sheltered Seaway pool — the islands and the broader Seaway navigation channel break the wind and give canoes and kayaks a calm interior to work. Designated boat launches on the parkway islands provide put-in access, and the inter-island channels open up day-route options. Afternoon winds on Lake St. Lawrence can pick up; the parkway-island water is the sheltered section.

Sailing & Boating

Lake St. Lawrence is the boating water — Seaway-pool depth and width with launch access from the Long Sault Parkway. The full-service marina end of the upper-Seaway boating product (Crysler Park Marina with transient slips and fuel) is in adjacent South Dundas, so a launch-and-day pattern from the parkway pairs naturally with a dock visit downriver. Seaway shipping traffic is on the navigation channel, separate from the parkway-island recreational pool.

Swimming & BeachStrong

Swimming & Beach

Three designated St. Lawrence Parks Commission swim beaches sit on the Long Sault Parkway: Mille Roches Beach near the Long Sault end of the parkway, McLaren Beach mid-chain, and Woodlands Beach beside Woodlands Campground at the Ingleside end. All three are managed day-use beaches with shoreline access to Lake St. Lawrence and require a valid parkway vehicle pass during the published season. Lake St. Lawrence is a sheltered Seaway pool — the islands break the wind and the swim conditions are calmer than open St. Lawrence shoreline.

Freshwater Fishing

The upper St. Lawrence at South Stormont sits in Fisheries Management Zone 20 — muskellunge, smallmouth and largemouth bass, walleye, and northern pike on Lake St. Lawrence, accessed from the Long Sault Parkway boat launches. Inland, the Raisin River and tributaries fall under FMZ 18. The two zones run on separate seasons and limits, and the FMZ 20 / FMZ 18 boundary cuts through South Stormont — anglers should confirm zone before each trip.

Snow Adventure

The OFSC-prescribed snowmobile trail network through eastern Ontario crosses South Stormont and connects Long Sault and Ingleside to the regional A and B trail corridors across the SDG counties. The network operates seasonally on a posted schedule and requires a valid OFSC Snowmobile Trail Permit; conditions are updated by the local snowmobile club through the OFSC interactive trail guide. Off the snowmobile network, parkway and Ault Park surfaces see informal snowshoe use when conditions allow.

Heritage & Culture

The Lost Villages Museum at Ault Park in Long Sault is the institutional anchor for the 1958 St. Lawrence Seaway relocation story — ten communities (Aultsville, Farran's Point, Dickinson's Landing, Wales, Moulinette, Mille Roches, Maple Grove, Santa Cruz, Woodlands, and Sheik's Island) flooded or relocated when the river was raised to create Lake St. Lawrence. The museum preserves and interprets relocated heritage buildings and the documentary record of the inundation. A short drive away, the Long Sault Parkway threads the islands left after the flooding, so the relocation history sits both in the museum and on the water itself. The museum operates on a posted seasonal schedule.
