New Brunswick is one of the thirteen provinces and territories of Canada. It is one of the three Maritime provinces and one of the four Atlantic provinces. It is bordered by Quebec to the north, Nova Scotia to the east, the Gulf of Saint Lawrence to the northeast, the Bay of Fundy to the southeast, and the U.S. state of Maine to the west. New Brunswick is roughly 83% forested and its northern half is occupied by the Appalachians. The province’s climate is continental behind snowy winters and self-denying summers.

New Brunswick has a surface area of 72,908 km (28,150 sq mi) and 775,610 inhabitants (2021 census). Atypically for Canada, only more or less half of the population lives in urban areas – predominantly in Moncton, Saint John and Fredericton.

In 1969, New Brunswick passed the Official Languages Act which began recognizing French as an recognized language, along subsequently English. New Brunswickers have the right to receive provincial admin services in the official language of their choice. About two thirds of the population are English speaking and one third is French speaking. New Brunswick is home to most of the cultural region of Acadia and most Acadians. New Brunswick’s variety of French is called Acadian French. There are seven regional accents.

New Brunswick was first inhabited by First Nations taking into account the Mi’kmaq and Maliseet. In 1604, Acadia, the first New France colony, was founded considering the inauguration of Port-Royal. For 150 years afterwards, Acadia changed hands multiple times due to numerous conflicts surrounded by France and the United Kingdom. From 1755 to 1764, the British deported Acadians en masse, an issue known as the Great Upheaval. This, along in imitation of the Treaty of Paris, solidified Acadia as British property. In 1784, following the initiation of many loyalists fleeing the American Revolution, the colony of New Brunswick was officially created, separating it from what is now Nova Scotia. In the before 1800s, New Brunswick prospered and the population grew rapidly. In 1867, New Brunswick arranged to join with Nova Scotia and the Province of Canada (now Quebec and Ontario) to form Canada. After Confederation, shipbuilding and lumbering declined, and protectionism disrupted trade past New England.

From the mid-1900s onwards, New Brunswick was one of the poorest regions of Canada, a fact eventually mitigated by transfer payments. However, the province has seen the highest eastward migration in 45 years in both rural and urban areas, as people from Ontario and other parts of Canada migrate to the area. As of 2002, the provincial GDP was derived as follows: services (about half being processing services and public administration) 43%; construction, manufacturing, and utilities 24%; real house rental 12%; wholesale and retail 11%; agriculture, forestry, fishing, hunting, mining, oil and gas lineage 5%; transportation and warehousing 5%. A powerful corporate amalgamation of large companies in New Brunswick is owned by the Irving Group of Companies. The province’s 2019 output was CA$38.236 billion, which is 1.65% of Canada’s GDP.

Tourism accounts for 9% of the labour force either directly or indirectly. Popular destinations adjoin the Hopewell Rocks, Fundy National Park, Magnetic Hill, Kouchibouguac National Park and Roosevelt Campobello International Park.
