Because of the extremely sensitive nature of ATCs for the protection of life*, and the additional danger to an affected individuals should the details of an authorization become public, it has been the RCMP's long-standing policy not to publicly disclose data related to ATCs for the protection of life. According to the RCMP, the release of any such information could create a serious threat to individuals, especially in cases where it became known by organized crime (or others) that the ATC holder was armed. Given the extremely small number of ATCs for the protection of life issued by the RCMP in Canada, and the real possibility that that information, alone or in combination with other information, could be used to identify the individual, the RCMP's position (is) that the release of authorizations by province could impact the safety of an individual.
