The Canada Lands Company plan for the Booth Street property in Ottawa.

      Canada Lands Company privatized the Federal Government of Canada's Natural Resources Complex in the Nation's Capital.
Half a dozen high-rise buildings will be constructed on 2.5 hectares or 6.5 acres of land:

The Kingston Penitentiary is another former Crown asset that the Canada Lands Company wants to capitalize. Imagine how many residential towers can be built on 21 acres of land. Of course the Pen will have to be reduced to rubble , to get rid of the perimeter walls, guard towers and the buildings. I believe that the entire Kingston Pen will be flattened, because only half of a penitentiary with gaping holes in the remaining wall will be an eyesore.
 The New Westminster Federal Penitentiary in British Columbia was wrecked, only the Gate House and a few buildings remain. The land was sold to real estate companies who built condos and townhouses. Even before the BC Pen was decommissioned, all the prison farm land that the inmates harvested was sold, to the City of New Westminster.

CityPlace in Toronto, a Canada Lands company project

The former Canadian National Railway lands on the Toronto waterfront were transferred to Canada Lands Company. Now the CLC owns the CN Tower, land beneath the Skydome/Rogers Centre and the Railway Lands.
The largest development in Toronto's history was created on 44 acres of CNR land.
Over 5,000 residential units were constructed at CityPlace, the condominiums range in height from 6 storeys to 49 storeys with the majority of condos ranging from 28 to 40 storeys.
