The National Capital Commission wanted to preserve the entire Experimental Farm in 2017.

The following quotes are from a document called "National Capital Commission - The Plan for Canada's Capital-2017-2067", page 36 and page 40 out of 95 pages:
National Institutions
     "In 2067, the national institutions will continue to be beacons of Canadian achievement in culture and science. They represent Canada to the world, and contribute significantly to the identity, pride and signature of the Capital."

The Central Experimental Farm, National Research Council and Communications Research Centre are National Scientific Institutions.

"The Central Experimental Farm, established in 1886, is a unique working farm in the heart of an urban region. The Experimental Farm is open to the public throughout the year, along with the adjacent 26-hectare Arboretum. This central asset of the Capital's urban green space network contributes to diversity and references the link from the Rideau Canal to the Ottawa River ecosystems. In the coming years, the long-term ecological and scientific outlook for preserving the Central Experimental Farm and the Arboretum should be revalidated in an update to the existing 2005 Master Plan."
