British expansion

Competition for control of the island of Newfoundland and its waters contributed to major ongoing conflicts and occasional wars between France and Britain.
The first major agreement between the two powers over access to this coastline came with the
Treaty of Utrecht

After the signing of the
Treaty of Paris in 1764 some of the Acadians returned and settled in the area that would become New Brunswick.
The effect of this migration can still be seen today as the province of New Brunswick is the only officially
bilingual province in Canada with over a quarter of residents speaking French at home.

with the signing of the
Treaty of Paris in 1783 many
loyalists from the United States settled in the region.
This influx of immigrants caused the
partition of Nova Scotia creating New Brunswick. Additionally these immigrants changed the culture and character of the region which had historically been French towards more British styled communities. It also marked one of the first large waves of migration to the area that established a predominantly
Anglo-Canadian population.
Some of the new settlers brought with them Black slaves. Also 3,000

In the last half of the 19th century the region's population grew due to the immigration from Ireland due to the
great potato famine.
