National Parks and Landmarks in the St. Lawrence Lowlands

The St. Lawrence Lowlands (Quebec/Ontario corridor) host several federal protected areas:

1. Thousand Islands National Park (ON): 20+ granite islands in the St. Lawrence River near Gananoque. Boat tours, paddling, hiking, camping. Part of UNESCO Frontenac Arch Biosphere.
2. Lake Superior National Marine Conservation Area (ON): Not in Lowlands proper, but on the Shield edge; protects freshwater marine ecosystems.
3. Mingan Archipelago National Park Reserve (QC): Gulf of St. Lawrence — limestone monoliths, seabirds, unique flora.
4. Forillon National Park (QC): Gaspé Peninsula tip — cliffs, whales, seals, historic cod fishery.
5. La Mauricie National Park (QC): Laurentian foothills — lakes, waterfalls, wolf/lynx habitat.
6. National Historic Sites: Fort Chambly, Fort Lennox, Lachine Canal, Sir George-Étienne Cartier, Louis S. St. Laurent — all in Lowlands.

Correction: Frontenac National Park is a provincial park (SEPAQ), not federal. "St. Lawrence Islands National Park" was renamed Thousand Islands National Park in 2013.
