Application of the precautionary principle by senior policy officials: results of a Canadian survey.

Though use of the controversial precautionary principle in risk management has increasingly been recommended as a guide for the construction of public policy in Canada and elsewhere, there are few data available characterizing its use in risk management by senior public policymakers. Using established survey methodology we sought to investigate the perceptions and terms of application of the precautionary principle in this important subset of individuals. A total of 240 surveys were sent out to seven departments or agencies in the Canadian government.
