Canada's Parliamentary Precinct cannot be subdivided or privatized.

 The Parliamentary Precinct includes: The Parliament Buildings; Library of Parliament; Supreme Court of Canada; Senate of Canada (former Union Station); Library and Archives Canada on Wellington Street;  properties on Wellington Street opposite Parliament Hill; the northern half of the Sparks Street Mall; the Dominion Observatory on Carling Avenue and the Lebreton Flats.

The Dominion Observatory Campus, Carling Avenue: "The popularity of the Observatory occurred when it opened in 1905, due to the support of Prime Minister Sir Wilfrid Laurier. Laurier's advocation reinforced the idea that this Observatory was to be considered an arm of the parliamentary precinct... At the time, it was recognized as a national achievement, where the nation's time would be kept, and of what would be a symbol of Canada's progress in astronomical science." ("Journal of the Study of Architecture in Canada", "Astronomer Mary Grey and the Architecture of Canada's Dominion Observatory" Royal Astronomical Society of Canada, Sharon Odell, Page 10/67.)

The Lebreton Flats are the Western Annex of the Parliamentary Precinct: House of Commons Ottawa February 23, 1965. The Hon. Mr. Cardin (Minister of Public Works.) Liberal."...Some time ago a decision was reached to construct the Department of National Defence headquarters building in the Lebreton flats area. At that time it was also decided that other government buildings should be located in the same area, forming a government complex of office buildings in the area from Parliament Hill west to lebreton flats."

Properties across from Parliament Hill on Wellington Street, and the northern half of the Sparks Street Mall; House of Commons Ottawa July 20, 1973. The Hon. Jean-Eudes Dube (Minister of Public Works.) "Mr. Speaker, for a number of years now it has been recognized that Parliament faces a severe space problem creating a limitation of its effective operation. As Parliament has become, through its committees and in other ways, even more involved in all aspects of the nation's life, it has become much more a year round operation and space available has fallen behind its needs as they have developed in the modern era."

"Moreover, concern has been expressed about the danger of visual encroachment on the beauty of the present parliamentary precinct which is one of the great symbols of Canada. We must ensure that nearby developments do not adversely affect it and furthermore, we have an opportunity, I believe to enhance the present precinct by enlarging and thereby completing it, in a fitting manner." 

"...We have all been aware that to properly house the expanded requirements of Parliament for the generations ahead in a way that would both complement and preserve the existing architectural beauty of the Parliament Buildings we must enlarge the present parliamentary grounds."

"I wish therefore to announce, Mr. Speaker, that I have today, on behalf of the government, filed a notice of intent to expropriate all the land and buildings in the area bounded by Wellington Street, Elgin Street, Sparks Street and Bank Street. The purpose of this expropriation as I have indicated is to protect the environment of Parliament from any development which could adversely affect it and simutaneously provide the land for an appropriate expansion of parliamentary facilities and other government requirements. The property of the United States Embassy has been excluded from this expropriation but discussions are well advanced for its acquisition."

"...I should like to add a few words, Mr. Speaker,with respect to the existing properties and especially the Sparks Street Mall. It is the government's intention that until Parliament's needs have been defined, there will be no disturbances whatsoever of the existing properties. This will be especially true of the commercial operations on Sparks Street. Some of the office accomodation in the upper levels may be used for government purposes from time to time" (more)

"The present character of the Mall will be preserved and enhanced." (more...)

The Chateau Laurier Hotel and Major's Hill Park were part of Parliament Hill: House of Commons Ottawa July 6, 1908: The Hon. Robert Laird Borden (Conservative). "...The park is a portion of the national domain, and a portion of the grounds of Parliament." (Construction of a Grand Trunk Railway hotel on Major's Hill Park.)

House of Commons Ottawa December 21, 1963. Legal title to Parliament Hill.

Laws protect the Parliamentary Precinct--- the landscapes and buildings are National Historic Sites of Canada; many land masses, highways, the Greenbelt and Gatineau Park were designated National Interest Land Mass properties in 1988 and Senate Bill S-203 protects National Historic Sites:

Senate Bill S-203.

Dow's Lake may not be part of the Parliamentary Precinct, but prime ministers, federal politicians and urban planner Jacques Greber wanted the Dow's Lake area preserved as a national park and a playground: House of Commons Ottawa March 2, 1939. Mr. Heaps, Co-operative Commonwealth Federation."...I know that the federal government has laid out a number of parks here, and open spaces used for playgrounds. To get a fairly accurate understanding we should know what use is being made of these open spaces to find out if Ottawa is receiving a square deal from the federal government."

The Hon. Charles Avery Dunning (Minister of Finance and Receiver General.)"...Take for example certain properties of the federal district commission surrounding Dow's lake. What was their actual value before the federal district built them up and turned them into the beautiful park which now exists?"

Urban planner Jacques Greber wanted the Central Experimental Farm to be "Ottawa's Central Park": "The Experimental Farm forms a central park within a residential area of the City of Ottawa." (The Greber Report of 1950, page 167/395 and a photograph of the site is included in the chapter.)
