Newfoundland and Labrador (sometimes abbreviated as NL) is the easternmost province of Canada, in the country’s Atlantic region. It is composed of the island of Newfoundland and the continental region of Labrador to the northwest, with a combined area of 405,212 square kilometres (156,500 sq mi). In 2018, the province’s population was estimated at 525,073. About 94% of the province’s population lives on the island of Newfoundland (and its neighbouring smaller islands), of whom more than half live on the Avalon Peninsula.

The province is Canada’s most linguistically homogeneous, with 97.0% of residents reporting English (Newfoundland English) as their mother tongue in the 2016 census. Historically, Newfoundland was also home to unique varieties of French and Irish, as well as the extinct Beothuk language. In Labrador, the indigenous languages Innu-aimun and Inuktitut are also spoken.

Newfoundland and Labrador’s capital and largest city, St. John’s, is Canada’s 20th-largest census metropolitan area and is home to almost 40 per cent of the province’s population. St. John’s is the seat of government, home to the House of Assembly of Newfoundland and Labrador and to the highest court in the jurisdiction, the Newfoundland and Labrador Court of Appeal.

Formerly a colony and then a dominion of the United Kingdom, Newfoundland gave up its independence in 1933, following significant economic distress caused by the Great Depression and the aftermath of Newfoundland’s participation in World War I. It became the tenth and final province to enter Confederation on March 31, 1949, as “Newfoundland”. On December 6, 2001, an amendment was made to the Constitution of Canada to change the province’s name to Newfoundland and Labrador.

Geography

Newfoundland and Labrador is the most easterly province in Canada, and is at the north-eastern corner of North America. The Strait of Belle Isle separates the province into two geographical parts: Labrador, which is a large area of mainland Canada, and Newfoundland, an island in the Atlantic Ocean. The province also includes over 7,000 tiny islands.

Newfoundland is roughly triangular. Each side is about 400 km (250 mi) long, and its area is 108,860 km2 (42,030 sq mi). Newfoundland and its neighbouring small islands (excluding French possessions) have an area of 111,390 km2 (43,010 sq mi). Newfoundland extends between latitudes 46°36′N and 51°38′N.

Labrador is also roughly triangular in shape: the western part of its border with Quebec is the drainage divide of the Labrador Peninsula. Lands drained by rivers that flow into the Atlantic Ocean are part of Labrador, and the rest belongs to Quebec. Most of Labrador’s southern boundary with Quebec follows the 52nd parallel of latitude. Labrador’s extreme northern tip, at 60°22′N, shares a short border with Nunavut on Killiniq Island. Labrador’s area (including associated small islands) is 294,330 km2 (113,640 sq mi). Together, Newfoundland and Labrador make up 4.06% of Canada’s area, with a total area of 405,720 km2 (156,650 sq mi).

Geology

The Long Range Mountains on Newfoundland’s west coast is the northernmost extension of the Appalachian Mountains.

Labrador is the easternmost part of the Canadian Shield, a vast area of ancient metamorphic rock comprising much of northeastern North America. Colliding tectonic plates have shaped much of the geology of Newfoundland. Gros Morne National Park has a reputation as an outstanding example of tectonics at work, and as such has been designated a World Heritage Site. The Long Range Mountains on Newfoundland’s west coast are the northeasternmost extension of the Appalachian Mountains.

The north-south extent of the province (46°36′N to 60°22′N), prevalent westerly winds, cold ocean currents and local factors such as mountains and coastline combine to create the various climates of the province.

Climate

Most of Newfoundland has a humid continental climate, cool summer subtype. Newfoundland and Labrador has a wide range of climates and weather, due to its geography. The island of Newfoundland spans 5 degrees of latitude, comparable to the Great Lakes. The province has been divided into six climate types, but broadly Newfoundland has a cool summer subtype of a humid continental climate, which is greatly influenced by the sea since no part of the island is more than 100 km (62 mi) from the ocean. Northern Labrador is classified as a polar tundra climate, southern Labrador has a subarctic climate.

Monthly average temperatures, rainfall and snowfall for four places are shown in the attached graphs. St. John’s represents the east coast, Gander the interior of the island, Corner Brook the west coast of the island and Wabush the interior of Labrador. Climate data for 56 places in the province is available from Environment Canada.

The data for the graphs is the average over thirty years. Error bars on the temperature graph indicate the range of daytime highs and night time lows. Snowfall is the total amount that fell during the month, not the amount accumulated on the ground. This distinction is particularly important for St. John’s, where a heavy snowfall can be followed by rain, so no snow remains on the ground.

Surface water temperatures on the Atlantic side reach a summer average of 12 °C (54 °F) inshore and 9 °C (48 °F) offshore to winter lows of −1 °C (30 °F) inshore and 2 °C (36 °F) offshore. Sea temperatures on the west coast are warmer than Atlantic side by 1-3 °C (approximately 2-5 °F). The sea keeps winter temperatures slightly higher and summer temperatures a little lower on the coast than inland. The maritime climate produces more variable weather, ample precipitation in a variety of forms, greater humidity, lower visibility, more clouds, less sunshine, and higher winds than a continental climate.
