The Official Languages Act was passed by the Legislative Assembly of the Northwest Territories in 1984. The act guarantees equal status for the use of Canada's two official languages for members of the public using government programs and services. The act also officially recognized the aboriginal languages spoken in the Northwest Territories.

In 1990 amendments to the act gave greater status to northern aboriginal languages and recognized the need to protect aboriginal culture through the promotion of the use of aboriginal languages. The 1990 amendments also included the creation of the position of the Languages Commissioner to be appointed by the Legislative Assembly for a term of four years.
