Up until 1996, the importance of the Saguenay Fjord (Québec, Canada) during the palaeohistoric period was unknown. Although numerous archaeological sites had been found in the vicinity of Tadoussac and in the Lac-Saint-Jean area, nothing was known about the use of the portion of the Saguenay River stretching between these two locations. However, since 1997, things have changed dramatically, and it is now known that this area has been heavily used for about 8,000 years. In fact, sites discovered at some specific points along the Fjord have provided thousands of archaeological remains. The wide variety of artefacts found provide us with an enhanced understanding of the day-to-day life of those who frequented the area during the paleohistoric period.
