In Canada, Government House is a title given to the official residences of the Canadian monarchy and various viceroys (the governor generals and the lieutenant governors). Though not universal, in most cases the title is also the building's sole name; for example, the sovereign's and governor general's principal residence in Ottawa is known as Government House only in formal contexts, being more generally referred to as Rideau Hall. The use of the term Government House is an inherited custom from the British Empire, where there were and are many government houses.
