Canada stretches from the Atlantic Ocean in the east to the Pacific Ocean in the west; to the north lies the Arctic ...
20–65 Ma. >65 Ma. A shield is a large area of exposed Precambrian crystalline igneous and high-grade metamorphic rocks that form tectonically stable areas. [1] These rocks are older than 570 million years and sometimes date back to around 2 to 3.5 billion years. [citation needed] They have been little affected by tectonic events following the ...
Canadian Shield. The Canadian Shield, Precambrian shield, makes up the bedrock geology highlighted by rocks and lakes [2] and a boreal forest area. There are transitional areas between boreal and tundra flora. [3] The lower boundary of the Canadian Shield cuts across the province diagonally from the latitude 57 degrees in the northwest to 54 ...

The provincial capital is St. John's, which had a population of 181,113 in 2005). St John's is located at the extreme eastern edge of the island on the Avalon Peninsula.
The Southern Province is a portion of Proterozoic rock that ranges in age from 2.5 billion to 600 million years old. It represents a subdivision of the much larger Canadian Shield and forms the bedrock of portions of Ontario, Canada and the U.S. states of Michigan and Minnesota. A few significant geologic features are situated in the Southern ...
The geology in Ontario consists of ancient Precambrian igneous and metamorphic rock which sits under younger, sedimentary rocks and soils. Around 61% of Ontario is covered by the Canadian Shield. The shield, as a whole, can further be divided into three sections- these are known as provinces. The northwestern parts of the Shield, located north ...
