Which landform regions make up Quebec’s territory?

Quebec’s territory is primarily composed of three major physiographic regions, which have shaped the province's settlement patterns and economic development:1

• St. Lawrence Lowlands: Stretching from Quebec City to Montreal along the St. Lawrence River, this fertile plain is the most densely populated region of the province and serves as the heart of its agricultural and industrial sectors.1
• Appalachian Uplands: Extending from the Gaspé Peninsula to the United States border, this region is characterized by forested hills, plateaus, and high plains. It also includes Anticosti Island.1
• Canadian Shield: Covering more than four-fifths of Quebec, this resource-rich hinterland lies north of the St. Lawrence Lowlands. It includes diverse landscapes ranging from the Laurentian Mountains to the northern taiga and tundra.1

Additionally, a small portion of the Hudson Bay Lowland—a wetland area primarily located in Ontario and Manitoba—extends into Quebec.2
