Canada has a constitutional democracy with three branches of government: the executive branch headed by the Prime Minister, the legislative branch consisting of the elected House of Commons and appointed Senate, and the judicial branch headed by the courts. While Canada has a monarch, the Queen is represented by the Governor General and is not involved in everyday governance, maintaining a role as a safeguard for democracy. Citizens elect representatives to the House of Commons on their behalf, as a direct democracy is not practical for a large nation.
