The Taiga Shield Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is an ecozone which stretches across Canada's subarctic region. Some regions exhibit exposed Precambrian bedrock of the Canadian Shield, the oldest of the world's geological formations.^[1] The world's oldest rocks, dating to four billion years, are found in the Canadian Shield north of Great Slave Lake.^[2]
