Final answer:
Canada's Head of State is Her Majesty Queen Elizabeth II, and her role is largely symbolic, with the Governor General performing her duties within Canada. The Prime Minister is the Head of Government.
Step-by-step explanation:
The Head of State of Canada is Her Majesty Queen Elizabeth II. Although the monarch's role in Canada is largely ceremonial, she remains the formal head of the country. The Governor General of Canada acts as the Queen's representative and performs the monarch's constitutional and ceremonial duties within Canada. The Prime Minister, in contrast, is the Head of Government and is responsible for running the country and setting government policy. The Queen's duties as Head of State in Commonwealth realms are often performed by her representatives, as her role is symbolic.
