Who was the first Prime Minister of Canada? The answer: Sir John A. Macdonald. He served from July 1, 1867, the day of Confederation, and played a key role in uniting the provinces to form the country we know today.

Macdonald was instrumental in shaping early Canadian politics and expanding the nation through major projects like the Canadian Pacific Railway. His leadership marked the beginning of Canada's journey as a self-governing country.

This foundational fact is commonly featured in Canadian Citizenship Test preparation, especially in history sections focused on Confederation and political leadership.
