Indigenous self-government in Canada in the context of Section Thirty-five of the Constitution Act, 1982

The Indian Act (French: Loi sur les Indiens) is a Canadian Act of Parliament that concerns registered Indians, their bands, and the system of Indian reserves. First passed in 1876 and still in force with amendments, it is the primary document that defines how the Government of Canada interacts with the 614 First Nation bands in Canada and their members. Throughout its long history, the act has been a subject of controversy and has been interpreted in different ways by both Indigenous Canadians and non-Indigenous Canadians. The legislation has been amended many times, including "over five major changes" made in 2002.

The act is very wide-ranging in scope, covering governance, land use, healthcare, education, and more on Indian reserves. Notably, the original Indian Act defines two elements that affect all Indigenous Canadians:

Section 35 of the Constitution Act, 1982 provides constitutional protection to the indigenous and treaty rights of indigenous peoples in Canada. The section, while within the Constitution of Canada, falls outside the Canadian Charter of Rights and Freedoms. The section does not define the term "aboriginal rights" or provide a closed list; some examples of the rights that section 35 has been found to protect are fishing, logging, hunting, the right to land (cf. aboriginal title) and the right to enforcement of treaties. There remains a debate over whether the right to indigenous self-government is included within section 35. As of 2006 the Supreme Court of Canada has made no ruling on the matter. However, since 1995 the Government of Canada has had a policy recognizing the inherent right of self-government under section 35.
