註釋 "In 1973, following the spill of oil from the tanker "Arrow" in Chedabucto Bay, Nova Scotia, the federal government issued a Cabinet Directive which specified Environment Canada's responsibilities in dealing with environmental emergencies. The Directive required Environment Canada to develop an environmental emergency program; to coordinate the federal government's response in the event of an environmental emergency; to develop and maintain the capability to provide technical advice in emergency situations; to prepare for and be able to respond to environmental emergencies, and to develop, assess and test new response tools. This mandate was supported in a Federal Policy for Emergencies approved in May 1995"--Introd.
