about 4.8 billion years ago
The Canadian shield are some of the oldest rocks on the Earth. According to the Bible, it is around 6000 years old. NOT billions of years old. Answer: The Canadian Shield contains the first solid land to be elevated above the sea level. The oldest of the rocks are precambrian in origin and were formed some 2.5 billion years ago. This makes the Shield about half as old as the Earth itself (4.5 billion years)
The Shield was formed around the Precambrian Era, so it is also called the Precambrian Shield instead of Canadian Shield that is right because there is only 7 not more or less! The order in which they where created are Canadian shield -Precambrian era Apalachians -Paleozoic era Great Lakes-St.Lawrence lowlands -Paleozoic era Innuitian Mountains -Mesozoic era Interior plains -Mesozoic era Western Cordillera -Cenozoic era Hudson bay arctic lowlands -Cenozoic era
