Toronto may very well be able to claim to have the first formally trained 'ambulance attendants' in North America, with the Toronto Police Force ambulance service staff receiving five days of formal training in their jobs from the St. John Ambulance Brigade in 1889. Training included first aid skills, anatomy and physiology. Such training for ambulance attendants was unheard of at that time, outside of military circles. The police constables assigned to the ambulance also did regular policing, when not required for ambulance calls. As the city grew and technology progressed, so did the ambulance service. The first motorized ambulance was actually purchased by a local funeral home in 1911, and the Toronto Police Ambulance Service began the conversion from horse-drawn to motorized vehicles in 1913, with the process largely completed by 1918. Over the years, the two City of Toronto departments would have their services supplemented by more than 130 individual ambulance operators, most of them private companies, and in suburban areas by several of the tiny, local fire departments. The two municipal services would finally be merged in 1933, when the Toronto Police Department turned the operation of their ambulances over to the Department of Public Health, and ended their involvement in the City's ambulance service.
