what kind of state is Canada?
As a constitutional monarchy, Canada’s Head of State is a hereditary Sovereign (Queen or King), who reigns in accordance with the Constitution: the rule of law. The Sovereign is a part of Parliament, playing an important, non-partisan role as the focus of citizenship and allegiance, most visibly during royal visits to Canada. Her Majesty is a symbol of Canadian sovereignty, a guardian of constitutional freedoms, and a reflection of our history.
