Final answer:
All of Canada became the property of Great Britain according to the Treaty of Paris (1763), which marked the end of the Seven Years' War and significantly altered the political landscape of North America.
Step-by-step explanation:
All of Canada became the property of Great Britain according to the Treaty of Paris (1763). This treaty marked the end of the Seven Years' War, also known as the French and Indian War in America, whereupon Britain emerged as the dominant power in eastern North America. Through this treaty, Britain was awarded everything east of the Mississippi River, including regions that France formerly controlled.
In contrast, the Quebec Act of 1774 extended the boundaries of Quebec into the Ohio Valley and allowed the French in Canada to maintain their legal system and Catholic faith. It did not, however, transfer ownership of any land to Great Britain. The Royal Proclamation of 1763 aimed to organize Great Britain's new North American empire and to stabilize relations with Native American tribes through regulation of trade, settlement, and land purchases on the western frontier.
Lastly, the British North America Act (1867) joined the British colonies of Nova Scotia, New Brunswick, and the Province of Canada into the Dominion of Canada, a self-governing entity within the British Empire.
