Resource towns, or "new towns," are the small, isolated communities built around resource-based industries and transportation, such as mining towns, mill towns, railway towns and fishing villages. Examples include: Fort McMurray, Alberta (oil); Grand Falls-Windsor, Newfoundland (pulp and paper); Glace Bay, Nova Scotia (coal); Black's Harbour, New Brunswick (fish packing); Murdochville, Québec (copper); Elliot Lake, Ontario (uranium); Snow Lake, Manitoba (copper, zinc); and Kitimat, British Columbia (aluminum). Resource development has long been recognized as a significant factor in shaping patterns of Canadian development. It has been argued that all Canadian urban growth ultimately depends on the production of staple products. Resource towns have been important agencies in this process of staple exploitation. Because of their dependence on single industries, the economies of resource towns are often unstable and precarious.
