The Canadian Shield The Canadian Shield is the principal area of North America where rocks of Precambrian age (i.e., those that are more than 542 million years old) are exposed at the surface. The shield was rifted apart between Canada and Greenland by seafloor spreading in the Labrador Sea and in Baffin Bay between 90 and 40 million years ago.
