Aamjiwnaang people launch lawsuit against chemical firm and Ontario over alleged environmental damage.

An indigenous community has launched a lawsuit against the Ontario provincial government and the petro-chemical company Suncor for failing to prevent pollution.

The community of Aamjiwnaang, located in the centre of Canada’s largest concentration of chemical industries, claims it has recorded rising asthma and cancer rates allegedly linked to air pollution.

The World Health Organisation says the area has highest rate of air pollution in the country, and the Aamjiwnaang believe environmental damage has caused genetic distortions in local wildlife.
