Who serves as the monarch's representative in Canada and also acts as the head of state?

The Governor-General serves as the monarch's representative in Canada and acts as the head of state. This role involves fulfilling constitutional and ceremonial duties, which include opening and closing sessions of Parliament, giving royal assent to legislation, and representing Canada during official events both domestically and abroad.

The Governor-General ensures that the functions of the monarchy are maintained within Canada's parliamentary democracy while acting in accordance with the advice of the Prime Minister and the Cabinet. This position highlights Canada's constitutional monarchy system, where the monarchy is a symbol of unity and continuity but does not engage in the day-to-day governance of the country.

In contrast, the Prime Minister is the head of government responsible for running the country, the Chief Justice heads the judiciary system and interprets the law, and ambassadors represent Canada in foreign nations and do not hold a role as head of state. This distinction clarifies the unique responsibilities of the Governor-General in representing the monarchy in the Canadian political system.
