During that time there were approximately 50 major language and 12 distinct language families in Canada, on top of that there were countless different dialects spoken by countless unique tribes. Language families are a group of languages that have evolved from one starting language. Although there were so many dialects, 94% of them are at risk of extinction. "As First Nations traditionally preserved and transmitted their culture and history through the oral tradition, no First Nations language in Canada had a writing system prior to European contact." (Quote from the University of British Colombia). It wasn't until the Europeans came over and taught them how did they start writing. Below is a map of the different language families.
