Downstream is about the environmental effects of
oil sands production in Alberta, Canada, as well as rare cancers being found downstream in the aboriginal community of
Fort Chipewyan. Because the film scrutinized the local government's pro-oil policies and was partially subsidized by the Alberta Film Fund, it prompted Alberta's Minister of Culture, Lindsay Blackett, to criticize the film, which in turn, led to controversy about whether films subsidized by the government should be allowed freedom of artistic expression.
