New Brunswick in the context of "Canadian Confederation"

Canada has ten provinces and three territories that are sub-national administrative divisions under the jurisdiction of the Canadian Constitution. In the 1867 Canadian Confederation, three provinces of British North America—New Brunswick, Nova Scotia, and the Province of Canada (which upon Confederation was divided into Ontario and Quebec)—united to form a federation, becoming a fully independent country over the next century. Over its history, Canada's international borders have changed several times as it has added territories and provinces, making it the world's second-largest country by area.

The major difference between a Canadian province and a territory is that provinces receive their power and authority from the Constitution Act, 1867 (formerly called the British North America Act, 1867). Territories are federal territories whose territorial governments have powers delegated to them by the Parliament of Canada. Powers are divided between the Government of Canada (the federal government) and the provincial governments by the Constitution Act, either exclusively or concurrently. A change to the division of powers between the federal government and the provinces requires a constitutional amendment. A similar change affecting the territories can be performed unilaterally by the government or Parliament of Canada.

Nova Scotia is a province in The Maritimes region of Canada, located on the nation's east coast. With an estimated population of over 1 million as of 2025, Nova Scotia is the most populous province in Atlantic Canada. Nova Scotia is also the second-most densely populated province in Canada, and the second smallest province by area. The province comprises the Nova Scotia peninsula and Cape Breton Island, as well as 3,800 other coastal islands. The province is connected to the rest of Canada by the Isthmus of Chignecto, on which the province's sole land border, with New Brunswick, is located.

Nova Scotia's capital and largest city is Halifax, which is home to over 45% of the province's population as of the 2021 census. Halifax is the twelfth-largest census metropolitan area in Canada, the largest municipality in Atlantic Canada, and Canada's second-largest coastal municipality after Vancouver.

Quebec (French: Québec) is Canada's largest province by area. Located in Central Canada, the province shares borders with the provinces of Ontario to the west, Newfoundland and Labrador to the northeast, New Brunswick to the southeast and a coastal border with the territory of Nunavut. In the south, it shares a border with the United States. Quebec has a population of around 8 million, making it Canada's second-most populous province only behind Ontario.

Between 1534 and 1763, what is now Quebec was the French colony of Canada and was the most developed colony in New France. Following the Seven Years' War, Canada became a British colony, first as the Province of Quebec (1763–1791), then Lower Canada (1791–1841), and lastly part of the Province of Canada (1841–1867) as a result of the Lower Canada Rebellion. It was confederated with Ontario, Nova Scotia, and New Brunswick in 1867. Until the early 1960s, the Catholic Church played a large role in the social and cultural institutions in Quebec. However, the Quiet Revolution of the 1960s to 1980s increased the role of the Government of Quebec in l'État québécois (the public authority of Quebec).

Atlantic Canada, also called the Atlantic provinces (French: provinces de l'Atlantique), is the region of Eastern Canada comprising four provinces: New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island. As of 2021, the landmass of the four Atlantic provinces was approximately 488,000 km (188,000 sq mi), and had a population of over 2.4 million people. The term Atlantic Canada was popularized following the admission of Newfoundland as a Canadian province in 1949. The province of Newfoundland and Labrador is not included in the Maritimes, another significant regional term, but is included in Atlantic Canada.

Maine (/meɪn/ MAYN) is a state in the New England region of the United States, and the northeasternmost state in the contiguous United States. It borders New Hampshire to the west, the Gulf of Maine to the southeast, and the Canadian provinces of New Brunswick and Quebec to the northeast and northwest, and shares a maritime border with Nova Scotia. It is the only state to border only one other state, which is New Hampshire. Maine is the largest state in New England by total area, almost as large as the combined area of the remaining five states. Of the 50 U.S. states, it is the 12th-smallest by area, the 9th-least populous, the 13th-least densely populated, and the most rural. As of 2024, Maine's population stood at a Census-estimated 1,405,012, the state's highest-ever population estimate. Maine's capital is Augusta, while its most populous city is Portland.

The territory of Maine has been inhabited by Indigenous populations for about 12,000 years, after the glaciers retreated during the last ice age. At the time of European arrival, several Algonquian-speaking nations governed the area and these nations are now known as the Wabanaki Confederacy. The first European settlement in the area was by the French in 1604 on Saint Croix Island, founded by Pierre Dugua, Sieur de Mons. The first English settlement was the short-lived Popham Colony, established by the Plymouth Company in 1607. A number of Irish and English settlements were established along the coast of Maine in the 1620s, although the rugged climate and conflict with the local Indigenous people caused many to fail. As Maine entered the 18th century, only a half dozen European settlements had survived. Loyalist and Patriot forces contended for Maine's territory during the American Revolution. During the War of 1812, the largely undefended eastern region of Maine was occupied by British forces with the goal of annexing it to Canada via the Colony of New Ireland, but returned to the United States following failed British offensives on the northern border, mid-Atlantic and south which produced a peace treaty that restored the pre-war boundaries. Maine was part of the Commonwealth of Massachusetts until 1820 when it voted to secede from Massachusetts to become a separate state. On March 15, 1820, under the Missouri Compromise, Maine was admitted to the Union as the 23rd state.

The history of post-confederation Canada began on July 1, 1867, when the British North American colonies of Canada, New Brunswick, and Nova Scotia were united to form a single Dominion within the British Empire. Upon Confederation, the Province of Canada was immediately split into the provinces of Ontario and Quebec. In 1870, Canada acquired the vast expanse of the continent controlled by the Hudson's Bay Company, which was eventually divided into new territories and provinces. British Columbia joined in 1871, and Prince Edward Island in 1873. Canada evolved into a fully sovereign state by 1982.

Before being part of British North America, the constituents of Canada consisted of the former colonies of Canada and Acadia from within New France which had been ceded to Great Britain in 1763 as part of the Treaty of Paris. French Canadian nationality was maintained as one of the "two founding nations" and legally through the Quebec Act which ensured the maintenance of the Canadian French language, Catholic religion, and French civil law within Canada, a fact which remains true today.

Vinland, Vineland, or Winland (Old Norse: Vínland hit góða, lit. 'Vinland the Good') was an area of coastal North America explored by Vikings. Leif Erikson landed there around 1000 AD, nearly five centuries before the voyages of Christopher Columbus and John Cabot. The name appears in the Vinland Sagas and describes a land beyond Greenland, Helluland, and Markland. Much of the geographical content of the sagas corresponds to present-day knowledge of transatlantic travel and North America.

In 1960, archaeological evidence of the only known Norse site in North America, L'Anse aux Meadows, was found on the northern tip of the island of Newfoundland. Before the discovery of archaeological evidence, Vinland was known only from the sagas and medieval historiography. The 1960 discovery further proved the pre-Columbian Norse exploration of mainland North America. Archaeologists found butternuts at L'Anse aux Meadows, which indicates voyages into the Gulf of Saint Lawrence as far as northeastern New Brunswick. L'Anse aux Meadows has been hypothesized to be the camp Straumfjörð mentioned in the Saga of Erik the Red.
