This paper outlines the development of emergency health planning as a function of government. Ten provinces have the basic responsibility for the organization, preparation and operation of medical, nursing, hospital and public health services in an emergency. The Department of National Health and Welfare is responsible for the provision of advice and assistance to the provincial and municipal governments in such matters. Eight provinces have now hired full-time planning staffs to co-ordinate the health planning of the Provincial Departments of Health and Provincial Emergency Measures Organization.Four major programs have been established. The first program provides for the continuity of leadership and guidance by health authorities at the federal, provincial and municipal level. Essential records have been developed and emergency legislation prepared. This program, however, will be of little use unless health services are organized at the municipal level. In this organizational program, advice and assistance have been provided to existing hospitals and departments of health in the conduct of disaster planning. The efforts of these agencies are co-ordinated by municipal health authorities into a community disaster plan. The third program deals with information and education of the general public and the health workers. This program is designed to make the family unit self-sufficient for up to seven days and the health worker prepared to undertake his emergency role. The first three programs are directed to the organization and training of manpower; the fourth program provides the necessary supplies. From the national medical stockpile of $18,000,000, some $12,000,000 has been received, packaged for long-term storage and distributed to regional depots across the country. To ensure their ready availability in time of emergency an agreement has been reached with seven provinces for the release of hospital disaster kits.
