Prince Edward Island in the context of "Eastern Canada"

Canadian Confederation (French: Confédération canadienne) was the process by which three British North American provinces—the Province of Canada, Nova Scotia, and New Brunswick—were united into one federation, called the Dominion of Canada, on July 1, 1867. This process occurred with the rising tide of Canadian nationalism that was then beginning to swell within these provinces and others. It reached fruition through the British North America Act, 1867 (today known as the Constitution Act, 1867) which had been based on resolutions agreed to by colonial delegates in the 1864 Quebec Conference, later finalized in the 1866 London Conference.

Upon Confederation, Canada consisted of four provinces: Ontario and Quebec, which had been split out from the Province of Canada, and the provinces of Nova Scotia and New Brunswick. The province of Prince Edward Island, which had hosted the first meeting to consider Confederation, the Charlottetown Conference, did not join Confederation until 1873. Over the years since Confederation, Canada has seen numerous territorial changes and expansions, resulting in the current collection of ten provinces and three territories.

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.

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.

The Gulf of St. Lawrence is a gulf that fringes the shores of the provinces of Quebec, New Brunswick, Nova Scotia, Prince Edward Island, Newfoundland and Labrador, in Canada, plus the islands Saint-Pierre and Miquelon, possessions of France, in North America.

The Gulf of St. Lawrence connects the Great Lakes to the Atlantic Ocean via the St. Lawrence River.

The Charlottetown Conference (French: Conférence de Charlottetown) was a political conference for representatives from colonies of British North America to discuss Canadian Confederation. The conference took place from September 1-9, 1864 in Charlottetown, Prince Edward Island. The conference had been planned as a meeting of representatives from the Maritime colonies; Nova Scotia, New Brunswick and Prince Edward Island. Britain encouraged a Maritime Union between these colonies, hoping that they would then become less economically and politically dependent on the Crown, and provide for greater economic and military power for the region in light of the American Civil War. However, another colony, the Province of Canada, comprising present-day Ontario and Quebec, heard news of the planned conference and asked that the agenda be expanded to discuss a union that would also include them.

Coincidentally there was a circus in Charlottetown during the conference, and it was much more interesting to the majority of the population. At the very least, the circus made making accommodations for all the delegates difficult, since there had not been a circus on Prince Edward Island in over 20 years. There was no one working at the public wharf at the foot of Great George Street when the Canadian delegates arrived on the steamship SS Victoria, so Prince Edward Island representative William Henry Pope had to handle receptions by himself, including rowing out to greet the new arrivals. Owing to the unexpectedly large number of visitors in the city, a sizeable proportion of the Canadian delegates remained aboard the Queen Victoria while others found accommodations at the Franklin. Meanwhile, circus-goers and the Maritime delegates had taken up the accommodations in town.

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, Wolastoqiyik and Passamaquoddy people are indigenous to the Maritimes, while Acadian and British settlements date to the 17th century. The Maritimes are within the Atlantic time zone, putting them one hour ahead of Quebec and the New England region of the United States.

Canadian French (French: français canadien, [fʁãˈsɛ kanaˈd͡zjɛ̃]) is the French language as it is spoken in Canada. It includes multiple varieties, the most prominent of which is Québécois (Quebec French). Formerly Canadian French referred solely to Quebec French and the closely related varieties of Ontario (Franco-Ontarian) and Western Canada—in contrast with Acadian French, which is spoken by Acadians in New Brunswick (including the Chiac dialect) and some areas of Nova Scotia (including the dialect St. Marys Bay French), Prince Edward Island and Newfoundland & Labrador (where Newfoundland French is also spoken).
