This paper is a report on the theoretical origins of a decolonizing research sensibility called Indigenous Metissage. This research praxis emerged parallel to personal and ongoing inquiries into historic and current relations connecting Aboriginal peoples and Canadians in the place now called Canada. I frame the colonial frontier origins of these relations--and the logics that tend to inform them--as conceptual problems that require rethinking on more ethically relational terms. Although a postcolonial cultural theory called metissage offers helpful insights towards this challenge, I argue that the postcolonial emphasis on hybridity fails to acknowledge Indigenous subjectivity in ethical ways. Instead, I present an indigenized form of metissage focused on rereading and reframing Aboriginal and Canadian relations and informed by Indigenous notions of place. Doing Indigenous Metissage requires hermeneutic imagination directed towards the telling of a story that belies colonial frontier logics and fosters decolonizing. (Contains 19 notes.)
