Jurisdiction is neither neutral nor objective; it reflects and shapes the relationships between people, land, and law, rendering it a site of contestation. In n’Daki Menan, the Temagami Anishinaabe (TAA) continue to assert jurisdiction over their traditional territory, a land of deep ecological and cultural significance — home to Ontario’s highest point and a diverse mixed forest they have stewarded for time immemorial. However, these assertions have been met with persistent efforts by the Crown to suppress Indigenous governance when it disrupts the flow of capital and resource extraction. This paper examines the TAA’s opposition to the expansion of Red Squirrel Road, the consequent blockades in 1989, and the ongoing struggle over jurisdiction in n’Daki Menan. While scholarship has analyzed the criminalization of Indigenous land defence, this research specifically focuses on the TAA’s resistance, demonstrating how their assertions of jurisdiction challenge the material, legal, and economic structures that sustain settler authority. Drawing on Deborah Cowen’s analysis of Wendigo infrastructure and Shiri Pasternak’s critique of jurisdiction, this study traces how roads, extraction projects, and state legal mechanisms act as enablers of capital accumulation and direct assertions of settler jurisdiction over Indigenous lands. Using an Indigenous political ecology framework, this paper documents how the TAA has actively resisted these jurisdictional encroachments through land defence and governance practices to further road expansions. These acts of resistance do not simply respond to state interventions; rather, they reaffirm the TAA’s enduring jurisdiction, positioning their governance as a force that continues to shape environmental, political, and economic landscapes.
