Fort Reliance is located on the east arm of Great Slave Lake, Northwest Territories, Canada. It was originally built in 1833 by George Back during the Arctic Land Expedition to the Arctic Ocean via the Back River. The expedition, partly scientific and partly searching for the missing John Ross, used Fort Reliance as a winter camp. Currently Fort Reliance, one of Canada's National Historic Sites, is listed by Parks Canada as the "Oldest continuously operating Hudson's Bay Company post, 1833". Together with the Prince of Wales Northern Heritage Centre, Parks Canada is working to preserve and protect the site.
