The Sir Richard Scott Building in Ottawa was a Government of Canada building.

     I know that for a fact, because my husband was part of the cleaning staff at the Richard Scott Building in 1982 and 1983, and he had to show ID to the Commissionaires at the front desk every time he showed up for work. My husband was a federal employee just as I was a government employee when I worked as a cleaning lady at the nearby Conference Centre.
   The office tower at 191 Laurier Avenue West in Ottawa is now owned by a company that plans to buy the Ottawa Public Library which is attached to the building.
Once the Ottawa Library is demolished, the owner will inevitably build high rise condominiums because they a own the air rights.
     Canada Lands Company and the real estate arm of the Canadian Pacific Railway were permitted to build skyscrapers on railway land on the Toronto waterfront, because they owned the air rights. Duff Roblin, head of the CPR's Marathon Realty even proposed demolishing Union Station to facilitate the construction of high rises.

Am I missing something here?
Does the Queen of England own L'Esplanade Laurier in downtown Ottawa?
A maintenance request from Public Works and Government Services Ottawa:
     "Her Majesty the Queen in Right of Canada is the owner in fee simple of the property (the "Property") municipally known as 171-181 Bank Street, 140 O'Connor Street and 300 Laurier Avenue West, in the City of Ottawa, and commonly referred to as "L'Esplanade Laurier". (Rehabilitation of "L'Esplanade Laurier - PWGSC-June 22, 2017.)

The term "Fee simple" means "A permanent and absolute tenure of an estate of land with the freedom to dispose of it at will, especially in full fee simple absolute, a freehold tenure, which is the main type of land ownership".
If the Queen owns L'Esplanade Laurier why are the commoners, the taxpayers of Canada, paying for the refurbishment of the complex?  Does the Queen own the Conference Centre in Ottawa, is that why I had to swear an Oath of Allegiance to Her Majesty, before a Commissionaire in 1982?
Do the occupants of a foreign country own our National Parks, the Royal Canadian Mint and Crown corporations. Who is pulling the strings at the Canada Lands Company, the Crown corporation that privatizes federal property, from the CN Tower to Tunney's Pasture to the Natural Resources Canada complex, Canada Post buildings and experimental farms.
A true Canadian would never authorize the demolition of Kingston Pen, the Prison for Women, the Saint Vincent de Paul Pen and New Westminster Pen---and the sale of prison farm land. Collins Bay Institution owns more than 800 acres of land.
A true Canadian would never evict thousands of federal employees from government buildings.
A real Canadian would never privatize the Canadian National Railway and convert the historic Canada Post Headquarters in Toronto into the Air Canada Centre.

My niece and I on the steps of 557 Laurier Avenue West, Ottawa- 1982. My husband and I lived in the building so that we could walk to work; in my case the Conference Centre. The apartments overlooking the Technical High School grounds no longer exist.
