The Atlas of Canada: Aboriginal Languages

This government of Canada Webpage is a part of a collection called the Atlas of Canada which depicts information about Canada and its history through the use of maps. It includes data and information about different indigenous languages where they are/located, what groups spoke what languages and whether those languages still exist. The site contains information from the 1996 census that highlights the decline of Aboriginal languages in areas throughout Canada.
