The boreal forest area gives way to the Eastern Canadian Shield taiga that covers northern Quebec and most of Labrador. Canadian Shield is a large area of Precambrian rock that forms the core of Canada. For example, in Alberta, Canada, it plunges under the mountains and plains to form a foundation under the province and it also stretches to the Western Cordillera in the west and Appalachians in the east, though the formations remain underground (HCF 2007). The Canadian Shield formed over 3 billion years through processes such as plate tectonics, erosion and glaciation. The climate in the boreal forest is characterized by long, very cold, dry winters and short, cool, moist summers. The Canadian coastline is more than 150,000 miles long. This is because the Canadian Shield has unusually large areas of relatively exposed rock from the Archean eon, roughly 2.5 to 4 billion years ago. What kind of rocks are in the Canadian Shield?

Wolves, black and grizzly bears and the lynx are the larger predators. The current surface expression of the shield is one of very thin soil on top of the bedrock, with many bare outcrops. With the exception of the Canadian Shield, the rocks of the North American Craton are buried deep within the continent and covered by soil and other material. The kimberlite eruptions then bring the diamonds from over 150 kilometres (93mi) depth to the surface. During this glaciation, the Shield was covered by the Laurentide Ice Sheet, a giant expanse of ice as much as 3 km thick. Because the Shield was formed through a series of orogenies, it was once a mountainous region. This arrangement was caused by severe glaciation during the last ice age, which covered the shield and scraped the rock clean. What using emissions scenarios can look like in practice.
