For decades, Canada has promised to reduce the overrepresentation of Indigenous Peoples in prison, yet today we make up just 5% of the population and one-third of those in federal custody, and half of incarcerated women. This is systemic racism rooted in colonialism, not individual failure. The case of Joey Toutsaint, a member of Black Lake Denesuline First Nation, held for over 3,000 days in intermittent solitary confinement in violation of the UN Nelson Mandela Rules, shows the profound harm this system continues to inflict on Indigenous Peoples. These conditions are driving disproportionate rates of self-harm and suicide and constitute a serious threat to the health and wellbeing of Indigenous Peoples. In accordance with the United Nations Declaration on the Rights of Indigenous Peoples, Canada must work in true partnership with First Nations to support self-determined approaches to justice, community safety, and healing by transferring resources and authority to Indigenous governments. The solution is clear, respect our right to self-determination and end the mass incarceration of Indigenous Peoples.
