The forestry industry
The colonising movement and the populating of the villages around Lac-Saint-Jean owes its existence in large part to the wood cutting industry. First, along the Saguenay River, then around Lac-Saint-Jean, the forestry industry has little by little developed and spread towards the interior of the territory frequented by the Pekuakamiulnuatsh.
It was during the XIXth century that the forestry industry came, gradually to replace the commerce in fur. This activity contributed strongly to dispossessing the Pekuakamiulnuatsh of their territories.
