This article presents the process that preceded the implementation of the research project Tan tshe eishi nashekanitsh ka ui pukuhutishuanuatsh Pekuakamiulnuatsh — vers une constitution des Pekuakamiulnuatsh. This research project has been co-constructed with the Ilnu community of Mashteuiatsh as a result of its desire to document its own legal traditions. As a starting point, this process was driven by the question of how others before us had gone about documenting indigenous legal traditions within the territory that is now Canada. The article therefore outlines the main methodological and theoretical approaches that currently guide the work of legal scholars and communities with indigenous legal traditions within this territory. Through this review of the literature crossing several disciplinary fields, we sought to identify tools and perspectives that could inspire the documentation of Indigenous legal traditions in Quebec. This article aims to bring together in a single document the main tools and perspectives that can be mobilised in the context of research on Indigenous legal orders.
