Which events in 1867 marked milestones for Confederation?

• A. Passage of the British North America Act and establishment of Canada as a dominion
• B. The formation of a republic in North America
• C. The dissolution of provincial governments in Canada
• D. Signing of a mutual defense treaty with Britain

Answer: (A)

The key milestone here is the legal birth of Canada as a country and the framework that makes it a federation. The British North America Act of 1867 was the law that united Ontario, Quebec, Nova Scotia, and New Brunswick into the Dominion of Canada and established the division of powers between a central federal government and the provinces. It created Canada as a self-governing dominion within the British Empire, giving it its own constitutional structure while still recognizing the Crown.

That’s why this option is the best: other statements describe scenarios that did not happen in 1867 or relate to Confederation itself. There was no formation of a republic in North America, the provinces were not dissolved, and no mutual defense treaty with Britain was signed that year.
