"While so much has been written on the origins and development of various aspects of modern medicine and health care in this province, little, if any, has been directed at the evolution of the ambulance service. It is in an attempt to rectify this omission that the writing of this history was undertaken." So says James A. Hanna in the introduction of his book. Rather than a detailed account of some several hundred individual services, Hanna confines himself to an overview of the evolution of ambulance transportation and care, from the horse drawn carriage to today's modern services, including air and bus ambulances. Hanna identifies four major periods: the early years, 1880-1934; the developing years, 1935-1965; the transition years, 1966-1974; and the modern years, 1975-1982. Each reflects crucial changes in ambulance service, from the types of vehicles used, their equipment and staff, to the introduction of government regulations and legislation. Hanna has an impressive list of credentials qualifying him as an authority in this field. He is a graduate of several related courses, including Humber College's ambulance and emergency care course. He has worked, taught, and lectured in the ambulance service field for both the private and government sectors. The book with its well-researched writing and top quality photographs is an excellent resource, if not the only one, on the subject of ambulance care in Ontario. George Gereben, Hamilton, ON.
