The National Network for Urban Aboriginal Economic Development project was developed as a partnership between the University of Northern British Columbia and the Prince George Aboriginal Business Development Centre with a goal of fostering economic development in urban aboriginal communities.
Their website includes a vast amount of research on urban aboriginal issues (education, economic development, traditional practices, etc) as well as links to other organizations and community groups working in this field.
This is a good starting point for anyone interested in doing research on urban aboriginals.
