However, other languages are also present, including:
* English: While less common than French in Quebec, English is widely spoken in the Lowlands, particularly in areas with a strong Anglophone presence like Montreal and Ottawa.
* Indigenous Languages: Several Indigenous languages are spoken in the region, including Mohawk, Algonquin, and Innu.
* Other Languages: Due to immigration, other languages such as Italian, Spanish, Arabic, and Mandarin are also present in the Saint Lawrence Lowlands.
Therefore, while French is the dominant language, the Saint Lawrence Lowlands is a multilingual region with a diverse linguistic landscape.
