The Vancouver Sun reports in its Thursday edition first nations leaders in Northern British Columbia are threatening to block all attempts to move oil through the province by rail. The unbylined item says the chiefs want to meet in the next 30 to 45 days to discuss a plan, adding oil-by-rail is putting their communities and the environment at risk. Five aboriginal leaders are leading the call to halt oil-by-rail as they cite the landmark Tsilhqot'in court decision, which they say reinforces the requirement for first nations to be consulted over the railway in their territory. Burns Lake First Nation Chief Dan George says oil by rail is a serious threat and the chiefs will explore safer alternatives. The chiefs are also against Enbridge's Northern Gateway pipeline proposal, but have agreed to consider Eagle Spirit Energy, a pipeline being pitched by an aboriginal businessman as an alternative. The new proposal would link Alberta's oil sands to a tanker terminal and refinery on the B.C. coast.
