Canadian Association of University Teachers (CAUT) released its Guide to Acknowledging First Peoples & Traditional Territory in September 2017. The document was reviewed by CAUT’s Aboriginal Post-Secondary Education Working Group and is an invaluable resource for acknowledging the First Peoples of Canada, on whose traditional territories our Great Lakes communities are situated. Where available, each community’s description page begins with a reference to the traditional territories of Indigenous communities and nations in that area.
