South Stormont.

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.
