This site is a link to an article on Aboriginal languages in danger of becoming extinct across Canada. Among other things the site identifies British Columbia as the province most in danger of losing Native languages and subsequently culture.
Useful statics on the number of Aboriginal languages and the decline over the years can be found throughout the article. It also discusses the problem in the context of education and the efforts being made to incorporate it into highschool and university programs.
Though it is not a scholarly article it brings up several important points related to the loss of language and culture that would be valuable to anyone researching these important topics for their project.
