The Canadian Shield, also called the Laurentian Shield or the Laurentian Plateau, is a geologic shield, a large area of exposed Precambrian igneous and high-grade metamorphic rocks. It forms the North American Craton, the ancient geologic core of the North American continent. Glaciation has left the area with only a thin layer of soil, through which exposures of igneous bedrock resulting from its long volcanic history are frequently visible. As a deep, common, joined bedrock region in eastern and central Canada, the shield stretches north from the Great Lakes to the Arctic Ocean, covering over half of Canada and most of Greenland; it also extends south into the northern reaches of the continental United States.
Gros Morne National Park is a Canadian national park and World Heritage Site located on the west coast of Newfoundland. At 1,805 km2 (697 sq mi), it is the second largest national park in Atlantic Canada after Torngat Mountains National Park, which has an area of 9,700 km2 (3,700 sq mi).
The Thousand Islands – Frontenac Arch region or the Frontenac Axis is an exposed strip of Precambrian rock in Canada and the United States that links the Canadian Shield from Algonquin Park with the Adirondack Mountain region in New York, an extension of the Laurentian Mountains of Québec. The Algonquin to Adirondacks region, which includes the Frontenac Axis or Arch, is a critical linkage for biodiversity and resilience, and one with important conservation potential. The axis separates the St. Lawrence Lowlands and the Great Lakes Lowlands. It has many distinctive plant and animal species. It is one of four ecoregions of the Mixedwood Plains.
Mount Caubvick is a mountain located in Canada on the border between Labrador and Quebec in the Selamiut Range of the Torngat Mountains. It is the highest point in mainland Canada east of the Rockies. The mountain contains a massive peak that rises sharply from nearby sea level. Craggy ridges, steep cirques and glaciers are prominent features of the peak.
Nachvak Fjord is a deep fiord in northern Labrador nearly 2 km (1.2 mi) wide and 20 km (12 mi) long. The fjord is divided in two arms on the western end called Tallek Arm and Tasiuyak Arm. The Torngat Mountains that surround Nachvak Fjord are the highest in Labrador, where both Mount Razorback to the north and Mount Caubvick to the south are located.
Torngat Mountains National Park is a Canadian national park located on the Quebec-Labrador Peninsula in the province of Newfoundland and Labrador. The park encompasses 9,700 km2 of mountainous terrain between Northern Quebec and the Labrador Sea. It is the largest national park in Atlantic Canada and the southernmost national park in the Arctic Cordillera. It partially contains the Torngat Mountains, the highest mountains in mainland Canada east of the Rocky Mountains.
Killiniq Island is a remote island in southeastern Nunavut and northern Newfoundland and Labrador, Canada. Located at the extreme northern tip of Labrador between Ungava Bay and the Labrador Sea, it is notable in that it contains the only land border between Nunavut and Newfoundland and Labrador. Most other islands off the northern coast of Quebec and Labrador belong exclusively to Nunavut. Some cartographic sources do not correctly show the island's geopolitical boundaries; for instance, the Commission de toponymie du Québec seems to show it as belonging to Quebec.
Newfoundland and Labrador is the easternmost province in Canada. The Strait of Belle Isle separates the province into two geographical regions, Labrador and the island of Newfoundland. The province also includes over seven thousand small islands.
The Arctic Cordillera is a terrestrial ecozone in northern Canada characterized by a vast, deeply dissected chain of mountain ranges extending along the northeastern flank of the Canadian Arctic Archipelago from Ellesmere Island to the northeasternmost part of the Labrador Peninsula in northern Labrador and northern Quebec, Canada. It spans most of the eastern coast of Nunavut with high glaciated peaks rising through ice fields and some of Canada's largest ice caps, including the Penny Ice Cap on Baffin Island. It is bounded to the east by Baffin Bay, Davis Strait and the Labrador Sea while its northern portion is bounded by the Arctic Ocean.
The Great Lakes-St. Lawrence Lowlands, or simply St. Lawrence Lowlands, is a physiographic region of Eastern Canada that comprises a section of southern Ontario bounded on the north by the Canadian Shield and by three of the Great Lakes — Lake Huron, Lake Erie and Lake Ontario — and extends along the St. Lawrence River to the Strait of Belle Isle and the Atlantic Ocean. The lowlands comprise three sub-regions that were created by intrusions from adjacent physiographic regions — the West Lowland, Central Lowland and East Lowland. The West Lowland includes the Niagara Escarpment, extending from the Niagara River to the Bruce Peninsula and Manitoulin Island. The Central Lowland stretches between the Ottawa River and the St. Lawrence River. The East Lowland includes Anticosti Island, Îles de Mingan, and extends to the Strait of Belle Isle.
The Baffin Mountains are a mountain range running along the northeastern coast of Baffin Island and Bylot Island, Nunavut, Canada. The ice-capped mountains are part of the Arctic Cordillera and have some of the highest peaks of eastern North America, reaching a height of 1,525–2,146 metres (5,003–7,041 ft) above sea level. While they are separated by bodies of water to make Baffin Island, they are closely related to the other mountain ranges that make the much larger Arctic Cordillera mountain range.
The Eastern Canadian Shield taiga is an ecoregion of Canada as defined by the World Wildlife Fund (WWF) categorization system.
The Baffin coastal tundra is a small ecoregion of the far north of North America, on the central north coast of Baffin Island in the Canadian territory of Nunavut. This is permafrost tundra with an average annual temperature below freezing.
The Canadian Arctic tundra is a biogeographic designation for Northern Canada's terrain generally lying north of the tree line or boreal forest, that corresponds with the Scandinavian Alpine tundra to the east and the Siberian Arctic tundra to the west inside the circumpolar tundra belt of the Northern Hemisphere.
The geology of Prince Edward Island formed as a result of strike-slip extension in the mountains formed by the Taconic orogeny, Salinic orogeny, and Acadian orogeny, which created an area of subsidence in the Gulf of St. Lawrence. The Maritime Rift resulted in the Magdalen Basin, which is actually a series of small basins surrounding the Gulf. In the Permian coal swamps formed in these basins, resulting in Atlantic Canada's extensive coal deposits, while in some cases, the swamps evaporated were replaced by gypsum evaporite. Up to 12 kilometers of late Paleozoic sediments filled the Maritime Rift as rivers transported sediments in from more distant highlands. The rock visible at the surface on Prince Edward Island is principally red sandstone and siltstone deposited during this period.
Caribou herds in Canada are discrete populations of seven subspecies that are represented in Canada. Caribou can be found from the High Arctic region south to the boreal forest and Rocky Mountains and from the east to the west coasts.
The Davis Highlands tundra ecoregion covers the Baffin Mountains on the northeast coast of Baffin Island and Bylot Island, facing Baffin Bay in Nunavut, northern Canada. The terrain is extremely rugged, heavily glaciated, with many deep fjords, and very cold. About half of the territory is moss and lichen tundra, the other half bare rock and ice. The region is wetter than the much drier regions to the southwest of the Baffin Islands.
The Torngat Mountain tundra ecoregion covers the Torngat Mountains on the northeastern tip of the Labrador Peninsula where the provinces of Quebec and Newfoundland and Labrador meet. The mountains feature glacially carved U-shaped valleys and deep fjords. The vegetation over most of the territory is that of arctic tundra, herbaceous cover, or bare rock. The region supports seasonal polar bears, black bears, and caribou. The Atlantic coast is on the Atlantic Flyway for migratory birds.
