Indigenous languages are the original languages spoken by First Nations, Inuit, and Métis peoples in what is now Canada. Over 70 distinct Indigenous languages exist, belonging to multiple language families, with as much diversity among them as exists among European or Asian languages. Centuries of colonization, residential schools, and assimilation policies severely damaged Indigenous languages—many are now endangered with few fluent speakers remaining, mostly Elders. The Indigenous Languages Act (2019) recognizes Indigenous language rights and supports revitalization efforts. Language is central to culture, identity, and traditional knowledge, making language loss devastating beyond mere communication loss. Revitalization efforts include immersion schools, language nests for young children, documentation projects, and technology applications. Inuktitut and Cree remain relatively strong with tens of thousands of speakers, while many other languages face critical endangerment. Supporting Indigenous language revitalization is a key reconciliation commitment.
