List of counties of New Brunswick

The Canadian province of New Brunswick has 15 counties according to the Territorial Divisions Act of New Brunswick. While they are former counties, they continue to define a regional community.

With the reorganization of local government legislation contained in the Robichaud government's reforms, collectively called the New Brunswick Equal Opportunity program, county municipalities ceased to function in 1966 and their councils were dissolved.

Another form of regional local government did not replace the county. Instead, many small village municipalities were created, with the surrounding predominantly rural areas remaining unincorporated.

Their use as census divisions continues, and are used along with their parishes, for registration of real estate among other things. They figure prominently in residents' sense of place and continue as significant threads in the Province's cultural fabric (i.e., most citizens always know which county they are in), and they still appear on some maps.

Origin
The territory of what is now New Brunswick was previously a part of the colony of Nova Scotia, which, in 1759, separated into counties for the first time. As part of this, all territory north of Kings County, including all of present-day New Brunswick, was erected as Cumberland County, until on April 30, 1765, when the Saint John River valley was erected as Sunbury County, although it would not be until 24 May 1770 that a boundary would be established between the two counties. Sunbury’s western boundary was described as starting at the head of the St. Croix River, following the north line to the Saint John River and then to the southern Canadian border. This description actually overlapped a part of Maine’s territory, as you would have needed to go far west, towards the area near the source of the Chaudière River. No further changes would be made until 1785, when, now being a British colony, New Brunswick had new counties established for itself.

Creation
In 1784, New Brunswick was separated from Nova Scotia to be established as its own colony. Within the next year, the new colony was divided into eight counties: Charlotte, Kings, Northumberland, Queens, Saint John, Sunbury, Westmorland and York. In January 1786, the first session of the New Brunswick Legislative Assembly was held in Saint John, at which the MLA’s passed An Act for the better ascertaining and confirming the Boundaries of Several Counties within this Province, and for subdividing them into Towns or Parishes. As the council worked on developing the original county lines, they desperately needed maps of the province, which, at the time, they seemingly lacked. As a result, they relied on two maps by Joseph Frederick Wallet DesBarres from 1780, the best candidates for a map of New Brunswick at the time. As the new boundaries were established, the former counties of Cumberland and Sunbury were disregarded, with the exception of the starting point of the boundary between Westmorland and Northumberland counties, which shared a resemblance to the old boundaries, though this might have been a coincidence.

The county lines were strategically drawn to align with the watersheds, a logical decision given that New Brunswick's settlements were developed along waterways. Additionally, the counties were able to be divided into three groups: the Bay of Fundy, the Saint John River and the North Shore.
