The Government of the Northwest Territories provides interpreting and translating services in French, English and seven northern aboriginal languages. Simultaneous interpreting was, until the end of the twentieth century, only delivered in Inuktitut. With increasing demand, and improvements to training programs, it is now provided in the Dene languages as well. Relay interpreting, a unique feature to the NWT interpreting services, plays an important role due to the multiple languages dealt with on a regular basis. This paper discusses the importance of, and problems encountered with, simultaneous interpreting in the NWT.
