Office of the Auditor General of Canada
Report 5 - Environmental Petitions Annual Report

Petition 388: Protection of the Central Experimental Farm as a research facility and a national historic site of Canada.
Date received: 28 January 2016.
Petitioner: Coalition to Protect the Central Experimental Farm National Historic Site of Canada.
Summary: The petition asks for information about the transfer of 60 acres of the Central Experimental Farm in Ottawa from the control of Agriculture and Agri-Food Canada to the National Capital Commission. It also addresses concerns about the negotiations to lease that land to the Ottawa Hospital Corporation for a 99-year period.
The Central Experimental Farm is a national historic site where various environmental scientific experiments are conducted. For instance, the Farm conducts experiments on the impact of climate change on agriculture and studies crop yields and soil biodiversity. The petition asserts that the proposed severance of some of the most significant acreage will have negative impacts on the Farm in it's role as both a research facility and a national historic site.
Issues:Agriculture; environmental assessment; governance; science and technology.
Federal departments and agency responsible for reply: Agriculture and Agri-Food Canada;

Status: Completed.

(I believe the following information provided by the Auditor General of Canada in this report is significant: " Petition 388 raised concerns about the Central Experimental Farm in Ottawa and the transfer of part of the property to the National Capital Commission for the possible construction of a hospital. The petition asked why an environmental assessment and public consultations were not carried out prior to the transfer. (Emphasis mine-A.C, creator of this blog savecfbrockcliffe.
Also, a traffic impact study was never conducted, and a Cultural  Heritage Impact Statement was never presented.)
