The purpose of this work is to study the international experience in the conservation and development of indigenous languages. An analysis is made of current Canadian law governing the protection of indigenous languages. Within the framework of a systematic approach, the study of preserving indigenous languages problem was carried out in connection with the most important elements of the political system in society. The method of comparison is used to compare the assessments made by the Canadian society of the current policy on the preservation of indigenous languages. The ethical and ideological foundations of the regulatory framework and the ongoing state policy to preserve the languages of Canada, including the principles of international law, the recognition of their own collective identities of indigenous peoples, are determined as well. The study reveals the consistency of the state and civil society institutions in Canada in assessing historical experience in preserving indigenous languages and the moral and ethical assessments of this activity, mediating modern forms of work.
