Sea Lion Arch and Sleeping Giant, Lake Superior shoreline, Ontario

Lake Superior National Marine Conservation Area (French: Aire marine nationale de conservation du Lac-Supérieur) is a National Marine Conservation Area (NMCA) on the north shore of Lake Superior in Ontario, and is a unit of the national park system. Established on September 1, 2015,[2] it is the largest freshwater marine protected area in the world.[3][4]

Although national marine parks and a reserve had been created previously, and managed as NMCAs, this was the first area in Canada to be designated a "National Marine Conservation Area" as defined by the Marine Conservation Areas Act.[5] Plans to create it were first announced by Canadian Prime Minister Stephen Harper on October 25, 2007, in Nipigon, Ontario.[6] The area is a unit of Canada's national park system administered by Parks Canada.

The conservation area extends 140 kilometres (87 mi) eastward from Thunder Bay,[3] from Thunder Cape in the west, at the tip of Sleeping Giant Provincial Park, to Bottle Point in the east, and stretches southward to the Canada-US border, linking with Isle Royale National Park.[7] The Nipigon River and Lake Nipigon lie to the north.[4]

Designation process

Proposals to protect the area were first suggested in the mid-1990s, and formal plans were first announced in 2002.[5]

The marine conservation area was proposed after discussion with provincial and First Nations representatives. The First Nations in the area, represented by Wilfred King, the regional grand chief of the northern Superior region, endorsed the proposal once they were satisfied that it respected the Robinson Superior Treaty of 1850.[5]

Parks Canada distributed questionnaires to local residents as a public consultation. 67% of respondents supported the "largest possible designation area", with 13% opposing any NMCA designation, and the remaining supporting some form of NMCA.[8]

In June 2015, the federal government introduced a bill to create the NMCA, which received royal assent on June 24.[2] The law specified that the NMCA would come into force on either the day of approval or on September 1, 2015—whichever came latest. With approval given in June, the park was legally created on September 1.

Ecology

Lake Superior National Marine Conservation Area covers roughly 10,000 km2 (3,861 sq mi) of lakebed, its overlaying freshwater, and associated shoreline on 60 km2 (23 sq mi) of islands and mainland.[7] The area is home to numerous species including herons, peregrine falcons, and bald eagles.[5][8] The spawning and schooling waters of deep coldwater fish, such as whitefish, lake herring, walleye, and lake trout will be protected by this zone.[8][9] Caribou foraging and calving areas are located on shore.[6][9] Lake Superior is home to about 70 fish species.[10]

The official designation prevents resource extraction or other operations which may damage the aquatic or terrestrial ecosystems in the conservation area.[11] However, per the agreement with the First Nations, it does not exclude all commercial marine activity, such as shipping, and commercial and sport fishing.[12]
