Conservation Area

The Lake Superior National Marine Conservation Area (LSNMCA) is located along the Ontario northern shores of Lake Superior. It spans approximately 10,000 km² (3,861 mi²) of Lake Superior’s lakebed, overlaying waters, and associated shorelines, including 60 km² (37 mi²) of islands and mainland. It the largest freshwater marine conservation area in the world. Established in 2015, the LSNMCA aims to protect the unique natural and cultural resources of the lake while providing opportunities for sustainable use and enjoyment.

The area includes a range of ecosystems, from deep waters to rocky shorelines and wetlands. It is home to diverse species of fish, birds, and other wildlife, many of which are significant to Indigenous communities and local ecosystems. The LSNMCA also preserves numerous archaeological sites, some of which are sacred to Indigenous peoples. Recreational activities within the conservation area include boating, fishing, kayaking, and wildlife watching. The region’s natural beauty and ecological significance make it a popular destination for nature enthusiasts, while conservation efforts ensure that human activities do not harm the environment. Local communities, including Indigenous groups, play a role in managing and monitoring the area.

The LSNMCA is part of Canada’s broader marine conservation efforts, which aim to safeguard marine biodiversity while allowing for sustainable economic activities. These efforts are essential for preserving the health of Lake Superior, which is the largest of the Great Lakes by surface area and holds over 12,000 cubic kilometres (2,880 cubic miles) of water. The conservation area’s establishment reflects Canada’s commitment to preserving its natural heritage and promoting responsible environmental stewardship.
