Rideau Hall is the official residence in Ottawa of the governor general of Canada. It stands in Canada's capital on a 36-hectare estate at 1 Sussex Drive, with the main building consisting of approximately 175 rooms across 9,500 square metres, and 27 outbuildings around the grounds. Rideau Hall's site lies outside the centre of Ottawa. It is one of two official vice-regal residences maintained by the federal Crown, the other being the Citadelle of Quebec.
Most of Rideau Hall is used for state affairs, only 500 square metres of its area being dedicated to private living quarters, while additional areas serve as the offices of the Canadian Heraldic Authority and the principal workplace of the governor general and their staff; either the term Rideau Hall, as a metonym, or the formal idiom Government House is employed to refer to this bureaucratic branch.
