 The Middlesex London Emergency Medical Services Authority delivers ambulance service to Middlesex and London in accordance with service and patient care standards set by the County of Middlesex and Ministry of Health and Long Term Care.Medical oversight for controlled medical acts is provided under the direction of the Southwestern Ontario Regional Base Hospital Program.The service is operated directly as a branch of the municipal government as an independent, third-service option provider, which means that the service is funded by the municipal tax base, and operates in much the same manner as any other municipal department, such as the police or fire department, or in some cases like a public utility, but retains its complete independence from all other departments.
