The Canadian Shield is a large geologic feature. Essentially, it is part of the earth’s crust that has been exposed by glacial erosion. It has a thin layer of topsoil, so doesn’t support agriculture, but does have trees, mostly coniferous. There are minerals that are mined, nickel, copper, gold etc.
This arrangement was caused by severe glaciation during the ice age, which covered the Shield and scraped the rock clean. The lowlands of the Canadian Shield have a very dense soil that is not suitable for forestation; it also contains many marshes and bogs (muskegs).
