Final answer:
The United Empire Loyalists began moving to Canada after the American Revolution, around 1783, with approximately 80,000 opting to evacuate with British assistance. Their arrival significantly shifted Canada's demographics from mostly French to predominantly British.
Step-by-step explanation:
The United Empire Loyalists began arriving in Canada shortly after the end of the American Revolution. When the war concluded, approximately 80,000 loyalists opted to evacuate with the British. The relocation was largely subsidized by the British Parliament. This movement of Loyalists significantly altered the demographic makeup of the region, transforming Canada from predominantly French to predominantly British.
Many of these Loyalists had hoped for a British victory during the American Revolution and had stayed in the American Colonies. Following the British defeat, they moved to Canada to remain British subjects. This migration included both white colonists and free Black people. The Loyalist migration played a crucial role in shaping the cultural and social landscape of the future Canada.
