What provinces are covered by the Canadian Shield?

The Canadian Shield is a vast geological area that forms one of the largest and oldest geological formations in the world. It primarily consists of exposed Precambrian rock and covers a significant portion of eastern and central Canada. The provinces and territories included in this region are Nunavut, the Northwest Territories, Saskatchewan, Manitoba, Ontario, Quebec, and Labrador.

This region is characterized by its rugged landscape, including numerous lakes, rivers, and forests, as well as its rich natural resources. The Canadian Shield is vital for mining operations, as it contains various minerals and metals. Its geological history illustrates significant tectonic activity and the formation processes that have shaped Canada's landscape over millions of years.

In contrast, the other choices listed either include regions not associated with the Shield or focus on provinces that are part of different geological regions. This context clarifies why the other options do not fit the criteria for covering the Canadian Shield and why the selection of provinces and territories provided in the correct answer is accurate.
