In Canada, there are governors at the federal and provincial levels of government who, within their jurisdictions, act as representatives of the Queen of Canada, who is Canada's Head of State. The federal governor is the Governor General of Canada, and the governor of each province is the Lieutenant Governor. The Governor General is appointed by the Queen on the advice of the Prime Minister of Canada, whereas the lieutenant governors are appointed by the Governor General on the advice of the Prime Minister. The role of the Governor General and of the lieutenant governors in Canada is largely ceremonial, although they do retain the authority to exercise reserve powers in exceptional circumstances.
