During the year 2007 Federal Minister of Public Works Michael Fortier sold several government buildings to a Vancouver-based company called Larco investments.This is how Michael Fortier described the real estate portfolio to a House of Commons committee:
     "I do not know how you came up with this $1.2 billion dollar shortfall, Ms. Bourgeois. It is not a shortfall, it is a surplus. What is more, at the end of 25 years taxpayers will not have to deal with what they have been dealing with for decades and that is worthless real property." (House of Commons Evidence - OGGO Committee, December 10, 2007.)
---------------------------------------------------
There was widespread opposition to the privatization of the government buildings, see the YouTube video "PSAC National President John Gordon delivers speech". 
--------------------------------------------------

(The above mentioned buildings were "reversionary" properties, meaning that they reverted to the people of Canada after 35 years. At the end of 25 years, either Larco or another private company will own the Skyline Towers, Thomas D'Arcy McGee Building, etc.
 I found the above document in a 1985 book at Library and Archives Canada on Wellington Street in Ottawa.---savecfbrockcliffe)

Michael Fortier, 2006: "The average age of the office space is approximately 44 years and several properties have reached their life expectancy."
