Canadian Shield

The Canadian Shield is a very special and old part of North America. It is made of some of the oldest rocks on Earth, formed a very long time ago when there was a lot of volcanic activity. These rocks are called Precambrian and are mostly igneous and metamorphic rocks.

This huge rocky area covers more than half of Canada and even reaches into parts of Greenland and the northern parts of the United States. It stretches from the Great Lakes all the way up to the Arctic Ocean. Because of glaciers, the land has only a thin layer of soil with the old bedrock often sticking out.

The Canadian Shield is home to many lakes and rivers, which are important for fish like walleye and northern pike. Birds such as Canada geese and loons also live there, along with animals like beavers, caribou, moose, and wolves. Some polar bears even live in places like Wapusk National Park.

This area is also important for mining, with valuable minerals such as nickel, gold, silver, and copper found here. Towns like Sudbury in Ontario have mines that dig up these minerals, showing just how special the Canadian Shield is.
