It is the primarily continental portion of the province and constitutes 71% of the province's area but is home to only 6% of its population. It is separated from the island of
Newfoundland by the
Strait of Belle Isle. It is the largest and northernmost geographical region in the four
Atlantic provinces.
Labrador occupies most of the eastern part of the
Labrador Peninsula. It is bordered to the west and south by the province of

Etymology
Labrador is named after
João Fernandes Lavrador, a Portuguese explorer who sailed along the coasts of the
Labrador Peninsula in 1498–99.

Labrador's name in the
Inuttitut/
Inuktitut language (spoken in
Nunatsiavut) is (), meaning "the big land" (a common English nickname for Labrador).
Geography
Labrador has a roughly triangular shape that encompasses the easternmost section of the
Canadian Shield, a sweeping geographical region of thin soil and abundant mineral resources. Its western border with Quebec is the drainage divide of the Labrador Peninsula. Lands that drain into the
Atlantic Ocean

are part of Labrador, while lands that drain into
Hudson Bay are part of Quebec. Labrador's extreme northern tip, at 60°22′N, shares a short border with Nunavut on Killiniq Island. Labrador also has a maritime border with Greenland. Northern Labrador's climate is classified as
polar, while Southern Labrador's climate is classified as
subarctic.
Labrador can be divided into four geographical regions: the North Coast, Central Labrador, Western Labrador, and the South Coast. Each of those regions is described below.
North Coast
From Cape Chidley to
Hamilton Inlet, the long, thin, northern tip of Labrador holds the
Torngat Mountains, named after an Inuit spirit believed to inhabit them. The mountains stretch along the coast from Port Manvers to
Cape Chidley, the northernmost point of Labrador. The Torngat Mountain range is also home to
Mount Caubvick, the highest point in the province. This area is predominantly Inuit, with the exception of a small Innu community,
Natuashish.
The North Coast is the most isolated region of Labrador, with
snowmobiles, boats, and planes being the only modern modes of transportation. The largest community in this region is
Nain.
Nunatsiavut
Nunatsiavut is an Inuit self-government region in Labrador created on June 23, 2005.
The settlement area comprises the majority of Labrador's North Coast, while the land-use area also includes land farther to the interior and in Central Labrador. Nain is the administrative centre.
Central Labrador
Central Labrador extends from the shores of
Lake Melville into the interior. It contains the
Churchill River, the largest river in Labrador and one of the largest in Canada. The hydroelectric dam at
Churchill Falls is the second-largest underground power station in the world. Most of the supply is bought by
Hydro-Québec

under a long-term contract. The
Lower Churchill Project will develop the remaining potential of the river and supply it to provincial consumers. Known as "the heart of the Big Land", the area's population comprises people from all groups and regions of Labrador.
Central Labrador is also home to
Happy Valley-Goose Bay. Once a refuelling point for plane convoys to Europe during

Other major communities in the area are

Innu reserve known as
Sheshatshiu.
Western Labrador
The highlands above the Churchill Falls were once an ancient hunting ground for the
Innu First Nations and settled trappers of Labrador. After the construction of the hydroelectric dam at Churchill Falls in 1970, the
Smallwood Reservoir has flooded much of the old hunting land—submerging several grave sites and trapping cabins in the process.
Western Labrador is also home to the
Iron Ore Company of Canada, which operates a large iron ore mine in
Labrador City. Together with the small community of
Wabush, the two towns are known as "Labrador West".
South Coast
NunatuKavut
From Hamilton Inlet to
Cape St. Charles/
St. Lewis,
NunatuKavut is the territory of the
NunatuKavummiut or Central-Southern Labrador Inuit (formerly known as the Labrador
Métis).
It includes portions of Central and Western Labrador, but more NunatuKavummiut reside in its South Coast portion: it is peppered with tiny Inuit fishing communities, of which
Cartwright is the largest.
The Labrador Straits
From Cape Charles to the Quebec/Labrador coastal border, the Straits is known for its Labrador sea grass (as is NunatuKavut) and the multitude of icebergs that pass by the coast via the
Labrador Current.

Time zones of Labrador
Most of Labrador (from
Cartwright north and west) uses
Atlantic Time (UTC−4 in winter, UTC−3 in summer). The south eastern tip nearest Newfoundland uses
Newfoundland Time (UTC−3:30 in winter, UTC−2:30 in summer) to stay co-ordinated with the more populous part of the province.
Climate of Labrador
Most of Labrador has a
subarctic climate
The subarctic climate (also called subpolar climate, or boreal climate) is a continental climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of ...
(
Dfc), but northern Labrador has a
tundra climate (ET) and Happy Valley - Goose Bay has a
humid continental (Dfb) microclimate. Summers are typically cool to mild across Labrador and very rainy, and usually last from late June to the end of August. Autumn is generally short, lasting only a couple of weeks and is typically cool and cloudy. Winters are long, cold, and extremely snowy, due to the
Icelandic Low. Springtime most years does not arrive until late April, with the last snow fall usually falling during early June. Labrador is a very cloudy place, with sunshine levels staying relatively low during spring and summer due to the amount of rain and clouds, before sharply dropping off during September as winter draws nearer.

History
Early history
Early settlement in Labrador was tied to the sea as demonstrated by the Innu (formerly called Montagnais) and Inuit, although these peoples also made significant forays throughout the interior.
It is believed that the
Norsemen
The Norsemen (or Northmen) were a cultural group in the Early Middle Ages, originating among speakers of Old Norse in Scandinavia. During the late eighth century, Scandinavians embarked on a Viking expansion, large-scale expansion in all direc ...
were the first Europeans to sight Labrador around 1000 AD. The area was known as ''
Markland'' in
Greenlandic Norse and its inhabitants were known as the ''
Skrælings''.In 1499 and 1500, the Portuguese explorers
João Fernandes Lavrador and
Pero de Barcelos reached what was probably now Labrador, which is believed to be the origin of its name.
Maggiolo's World Map, 1511, shows a solid Eurasian continent running from Scandinavia around the North Pole, including Asia's arctic coast, to Newfoundland-Labrador and Greenland. On the extreme northeast promontory of North America, Maggiolo place names include ''Terra de los Ingres'' (Land of the English), and ''Terra de Lavorador de rey de portugall'' (Land of Lavrador of the King of Portugal). Farther south are the phrases ''Terra de corte real e de rey de portugall'' (Land of the Royal Court and of the King of Portugal) and ''Terra de pescaria'' (Land for Fishing). In the 1532 Wolfenbüttel map, believed to be the work of
Diogo Ribeiro, along the coast of Greenland, the following legend was added: ''As he who first sighted it was a farmer from the Azores Islands, this name remains attached to that country.'' This is believed to be João Fernandes. For the first seven decades or so of the sixteenth century, the name Labrador was sometimes also applied to what is now known as Greenland. Labrador ("lavrador" in Portuguese) means husbandman or farmer of a tract of land (from "labor" in Latin) – the land of the labourer. European settlement was largely concentrated in coastal communities, particularly those south of St. Lewis and Cape Charles, and are among Canada's oldest European settlements.
In 1542, Basque mariners came ashore at a natural harbour on the northeast coast of the Strait of Belle Isle. They gave this "new land" its Latin name ''Terranova''. A whaling station was set up around the bay, which they called ''Butus'' and is now named Red Bay after the red terracotta roof tiles they brought with them. A whaling ship, the ''San Juan'', sank there in 1565 and was raised in 1978.
The
Moravian Brethren of
Herrnhut,
Saxony, first came to the Labrador Coast in 1760 to minister to the migratory Inuit tribes there. They founded Nain, Okak, Hebron, Hopedale and Makkovik. Quite poor, both European and First Nations settlements along coastal Labrador came to benefit from cargo and relief vessels that were operated as part of the
Grenfell Mission (see
Wilfred Grenfell). Throughout the 20th century, coastal freighters and ferries operated initially by the
Newfoundland Railway and later
Canadian National Railway/
CN Marine/
Marine Atlantic became a critical lifeline for communities on the coast, which for the majority of that century did not have any road connection with the rest of North America.

, which ended the war, New France (including Labrador, though excluding the islands of
Saint Pierre and Miquelon southwest of Newfoundland) was transferred to the British, who administered the northern portion of it as the
Province of Quebec until splitting it in two in 1791, with Labrador located in
Lower Canada. However, in 1809, the British Imperial government detached Labrador from Lower Canada for transfer to the separate, self-governing
Newfoundland Colony.

The Canadian government built a major air force base at
Goose Bay, at the head of
Lake Melville during the Second World War, a site selected because of its topography, access to the sea, defensible location, and minimal fog. During the Second World War and the Cold War, the base was also home to American, British, and later German, Dutch, and Italian detachments. Today, Serco, the company contracted to operate

Mid-Canada Line and
DEW Line systems. Today, the remaining stations are automated as part of the
North Warning System; however, the military settlements during the early part of the Cold War surrounding these stations have largely continued as local Innu and Inuit populations have clustered near their port and airfield facilities.
During the first half of the 20th century, some of the largest
iron ore deposits in the world were discovered in the western part of Labrador and adjacent areas of Quebec. Deposits at
Mont Wright,
Schefferville, Labrador City, and Wabush drove industrial development and human settlement in the area during the second half of the 20th century.
The present community of
Labrador West is entirely a result of the iron ore mining activities in the region. The Iron Ore Company of Canada operates the
Quebec North Shore and Labrador Railway to transport ore concentrate south to the port of
Sept-Îles, Quebec, for shipment to steel mills in North America and elsewhere.
During the 1960s, the
Churchill River (Labrador name: Grand River) was diverted at
Churchill Falls, resulting in the flooding of an enormous area – today named the Smallwood Reservoir after
Joey Smallwood, the first premier of Newfoundland. The flooding of the reservoir destroyed large areas of habitat for the threatened Woodland Caribou. A hydroelectric generating station was built in Labrador as well as a transmission line to the neighbouring province of Quebec.
Construction of a large
hydroelectric dam project at
Muskrat Falls began in 2012 by
Nalcor Energy and the Province of Newfoundland. Muskrat Falls is 45 km (30 miles) west of
Happy Valley-Goose Bay on the Grand River (Newfoundland name: Churchill River). A transmission line began construction in October 2014 and was completed in 2016 that delivers power down to the southern tip of Labrador and underwater across the Strait of Belle Isle to the Province of Newfoundland in 2018.
From the 1970s to early 2000s, the
Trans-Labrador Highway was built in stages to connect various inland communities with the North American highway network at
Mont Wright, Quebec (which in turn is connected by a highway running north from
Baie-Comeau, Quebec). A southern extension of this highway has opened in stages during the early 2000s and is resulting in significant changes to the coastal ferry system in the Strait of Belle Isle and southeastern Labrador. These "highways" are so called only because of their importance to the region; they would be better described as roads, and were not completely paved until July 2022.
A study on a
fixed link to Newfoundland, in 2004, recommended that a tunnel under the
Strait of Belle Isle, being a single railway that would carry cars, buses and trucks, was technologically the best option for such a link.
However, the study also concluded that a fixed link was not economically viable. Conceivably, if built with federal aid, the 1949 terms of union would be amended to remove ferry service from

Although a

Route 389, starting approximately from Baie-Comeau to , is of an inferior alignment, and from there to , the provincial border, is an accident-prone section notorious for its poor surface and sharp curves. Quebec in April 2009 announced major upgrades to Route 389 to be carried out.
Route 389 and the Trans-Labrador Highway were added to Canada's
National Highway System in September 2005.

Newfoundland and Labrador House of Assembly.
Boundary dispute

In 1809, Labrador was transferred from Lower Canada to the Newfoundland Colony, but the inland boundary of Labrador had never been precisely stated.
Newfoundland argued it extended to the height of land, while Canada, stressing the historical use of the term "Coasts of Labrador", argued the boundary was inland from the high-tide mark. As Canada and Newfoundland were separate

, the matter was referred to the
Judicial Committee of the Privy Council (in London). Their decision set the Labrador boundary mostly along the coastal watershed, with part being defined by the
52nd parallel north. One of Newfoundland's conditions for joining Confederation in 1949 was that this boundary be entrenched in the Canadian constitution.
[ While this border has not been formally accepted by the Quebec government, the Henri Dorion Commission () concluded in the early 1970s that Quebec no longer has a legal claim to Labrador.
In 2001, Parti Québécois cabinet ministers Jacques Brassard and Joseph Facal erroneously reasserted that Quebec has never recognized the 1927 border:
]
Self-government
A Royal Commission in 2002 determined that there is some public pressure from Labradorians to break from Newfoundland and become a separate province or territory.
Indigenous self-government
After decades of negotiation with the provincial and federal governments, the Nunatsiavut region of northern and northeastern Labrador was created in 2005 as an autonomous region with its own elected Assembly and executive drawn from members of the region's Assembly. Some of the Innu nation would have the entirety of Labrador become a homeland for them, much as Nunavut and Nunatsiavut is for the Inuit, as a good portion of Nitassinan falls within Labrador's borders; a 1999 resolution of the Assembly of First Nations claimed Labrador as a homeland for the Innu and demanded recognition in any further constitutional negotiations regarding the region.
Labrador's Innu became status Indians under the '' Indian Act'' in 2002. Natuashish became a federal Indian reserve in 2003. Sheshatshiu became a federal reserve in 2006.
The Labrador Inuit Association had filed a land claim for portions of Labradorian land in 1977. In 1988, the Labrador Inuit Association, the government of the province of Newfoundland, and the government of Canada

began negotiations based on the land claim. An agreement-in-principle was achieved in 2001, and on May 26, 2004, the agreement was ratified by over 75% of eligible voters subject to the land claim. On January 22, 2005, the Inuit of Nunatsiavut signed the Labrador Inuit Lands Claims Agreement with the federal and provincial governments covering of land, including the entire northern salient of Labrador north of Nain as well as a portion of the Atlantic coast south of there. The agreement also includes of sea rights. Although the Inuit will not own the whole area, they were granted special rights related to traditional land use, and they will own designated Labrador Inuit Lands. The agreement also establishes the Torngat Mountains National Park in the northern area of the land claim. The agreement was ratified by the Labrador Inuit, the General Assembly of Newfoundland and Labrador, and the Parliament of Canada

, where it received Royal Assent on June 23, 2005, whereafter elections would be held for the Nunatsiavut Assembly and self-government would begin.
In the late 1970s, the Labrador Metis Association was created by the inhabitants of Labrador's southern coast to gain recognition as a distinct ethnocultural group, as at the time despite a pre-existing treaty protected under the constitution, the "Inuit-Metis" were considered to be merely the descendants of Inuit who had joined Western society. Little was known about the history of the "Inuit-Metis" of the time. In 2006, the Labrador Metis Association initiated a project with Memorial University of Newfoundland to better understand their past through the Community-University Research Association (CURA). Following research by CURA, the "Labrador Metis" were understood to be a continuation of the Inuit of southern Labrador. In 2010, the Labrador Metis Association changed its name to reflect their newly discovered heritage, and became the NunatuKavut Community Council. The Southern Inuit of NunatuKavut, who are also seeking self-government, have their land claim before the Government of Canada. The Government of Newfoundland and Labrador refuses to recognise or negotiate with the Inuit of NunatuKavut until their claim has been accepted by the Government of Canada.
