Regional Assessment in the Ring of Fire Area
The regional assessment will be conducted in the area centred on the Ring of Fire mineral deposits in northern Ontario, approximately 540 kilometres northeast of Thunder Bay. The regional assessment aims to gather information and data on the region; understand potential effects from past, existing and future development in the Ring of Fire area; and will inform and improve future impact assessments. Indigenous partners and the Impact Assessment Agency of Canada are co-leading the regional assessment and will provide Indigenous communities and organizations, federal and provincial governments, non-government organizations and the public opportunities to meaningfully participate.
Indigenous partners include: Aroland First Nation, Attawapiskat First Nation, Constance Lake First Nation, Eabametoong First Nation, Fort Albany First Nation, Ginoogaming First Nation, Kashechewan First Nation, Long Lake #58 First Nation, Marten Falls First Nation, Missanabie Cree First Nation, Moose Cree First Nation, Neskantaga First Nation, Nibinamik First Nation, Webequie First Nation, and Weenusk First Nation. Administrative support is provided by the Matawa and Mushkegowuk Councils.
To support engagement and information sharing, an Information Sharing Platform (ISP) has been developed for this assessment. The ISP offers additional tools to explore geospatial data through interactive maps, visual summaries and storytelling tools, and thematic content.
