Canada became a British Colony in a result of what event

Canada became a British possession after the end of the Seven-Years war and the signing of Treaty of Paris in 1763. The French first ruled Canada after the European contact, which explains why places like Montreal and Quebec have strong French heritage. The Seven-Years War resulted in British victory over the French, and so the French have to hand over the keys to Canada and settle for fishing rights off Newfoundland and the islands of St. Pierre and Miquelon.

Beginning with the Treaty of Paris (1763), where the New France, of which Canada was previously part of, surrendered to the British Empire. Consecutively, territories, provinces, and other protectorates that were part of British North America would be added to Canada.
