Final answer:
Brock likely stayed in Canada due to the strong sense of loyalty to Britain held by English Canadians and the complex feelings of identity among French Canadians, who felt abandoned by France and marginalized within Canada itself.
Step-by-step explanation:
During the American Revolution, English and French Canadians largely remained loyal to Britain, resisting calls to join the American cause against the Crown. After the revolution, many Loyalists from the American Colonies moved to Canada to continue living under British rule rather than become citizens of the new United States. This migration solidified the loyalty of English Canadians to Britain and was further exemplified by Canada's resistance to American invasion in 1812. For French Canadians, the connection to France had been severed after they were conquered by the British in 1760. They felt abandoned and were later subjected to language rights restrictions, which contributed to their feeling of being second-class citizens. The election of 1917 saw bitter divisions over conscription, leading to riots in Montreal and Quebec City, illustrating the complexity of Canadian loyalty and identity.
