 With the settlement of Témiscouata and la Matapédia, the name start imposing itself between 1920 and 1960, when a number of enterprises and organisms of the region delimitated by the Roman Catholic Archdiocese of Rimouski and Rivière-du-Loup, like the "Compagnie de transport du Bas St-Laurent" and the "Compagnie de Pouvoir du Bas-Saint-Laurent" or the newspaper "l'Écho du Bas St-Laurent" adopt it.After being eclipsed for two decades when the State tried to erase regional differences by putting in place shared administrative structures east of the Quebec, the start of the 1980s sees this policy change, as the great region Bas-Saint-Laurent-Gaspésie is split into two different territories, being more accurate for the distinctive cultural traditions of these regions.The evolution of the toponymy of the region takes root in the different steps of its development, with at first the initial settlement by First Nations, followed by a progressive settlement by French-speaking colonists starting in the 18th century, but mostly in the 19th, a small Scottish presence starting in the 1800s, with activities centred on agriculture and the exploitation of its waters and forests.
