The Maritimes, also called the Maritime provinces, is a region of Eastern Canada consisting of three provinces: New Brunswick, Nova Scotia, and Prince Edward Island. The Maritimes had a population of 1,899,324 in 2021, which makes up 5.1% of Canada's population. Together with Canada's easternmost province, Newfoundland and Labrador, the Maritime provinces make up the region of Atlantic Canada.
Located along the Atlantic coast, various aquatic sub-basins are located in the Maritimes, such as the Gulf of Maine and Gulf of St. Lawrence. The region is located northeast of New England in the United States, south and southeast of Quebec's Gaspé Peninsula, and southwest of the island of Newfoundland. The notion of a Maritime Union has been proposed at various times in Canada's history; the first discussions in 1864 at the Charlottetown Conference contributed to Canadian Confederation. This movement formed the larger Dominion of Canada. The Mi'kmaq, Maliseet and Passamaquoddy people are indigenous to the Maritimes, while Acadian and British settlements date to the 17th century.
The word maritime is an adjective that means of the sea; thus any land adjacent to the sea can be considered maritime. But the term Maritimes has historically been collectively applied to New Brunswick, Nova Scotia and Prince Edward Island, all of which border the Atlantic Ocean. In other provinces except Newfoundland and Labrador in the Atlantic Ocean and British Columbia in the Pacific Ocean, human settlement along the coast is sparse. The Hudson Bay area is northerly and has a severe climate, and the majority of the populations of Ontario, Quebec and Manitoba reside far inland.
The pre-history of the Canadian Maritimes begins after the northerly retreat of glaciers at the end of the Wisconsin glaciation over 10,000 years ago; human settlement by First Nations began in the Maritimes with Paleo-Indians during the Early Period, ending around 6,000 years ago.
The Middle Period, starting 6,000 years ago, and ending 3,000 years ago, was dominated by rising sea levels from the melting glaciers in polar regions.
