Canadian aboriginals sue over chemical pollution

One indigenous community has launched a lawsuit against the Canadian government and the petrochemical company SunCor for failing to prevent pollution that has has taken a severe toll on their environment and health. The community of Ammjiwnang, located in the centre of Canada's largest concentration of chemical industries around the Great Lakes, says that it has also seen rising asthma and cancer rates most likely linked to air pollution, which the World Health Organisation says is higher in the area than anywhere else in the country. The Ammjiwnang also say the pollution has caused genetic distortions in wildlife populations in the area. Daniel Lak reports from the port town of Sarnia.
