What is the largest landform region in Canada?

The correct answer is the Canadian Shield, which is recognized as the largest landform region in Canada, covering more than half of the country’s land area. This region is characterized by its ancient, exposed Precambrian rock, extensive forests, and a rich variety of lakes and rivers. The Canadian Shield is significant because it heavily influences Canada's geography, natural resources, and ecosystems.

The vastness of this region also plays a crucial role in the distribution of natural resources, such as minerals and timber, making it economically important. Furthermore, its unique landscape shapes climate patterns and habitats within Canada. The presence of rugged terrain and rich biodiversity underscores the ecological importance of the Canadian Shield, making it a foundational aspect of Canada's environmental identity.
