<P> The Canadian Shield is a physiographic division , consisting of five smaller , physiographic provinces : the Laurentian Upland , Kazan Region , Davis , Hudson and James . The shield extends into the United States as the Adirondack Mountains ( connected by the Frontenac Axis ) and the Superior Upland . The Canadian Shield is U-shaped and is a subsection of the Laurentia craton signifying the area of greatest glacial impact ( scraping down to bare rock ) creating the thin soils . The Canadian Shield is more than 3.96 billion years old . The Canadian Shield once had jagged peaks , higher than any of today 's mountains , but millions of years of erosion have changed these mountains to rolling hills . </P>
