All Communication Operators are at minimum trained and licensed Emergency medical responders (EMR), and receive intensive in-house training. All Operators have obtained the National Academy of Emergency Dispatch System's Emergency Telecommunicator (ETC) Certification, Emergency Medical Dispatcher (EMD) Certification and Emergency Fire Dispatcher (EFD) Certification. They are also certified in use of the Medical Priority Dispatch System (MPDS) and Fire Priority Dispatch System (FPDS). Both of these dispatch systems are used internationally and guarantee consistent and accurate assessment of the caller's emergency as well as consistent dispatching. These system help alleviate problems where the caller may exaggerate or downplay the emergency, and provides the call taker with a consistent approach to every call. All Communication Operators go through ongoing training with these systems and go through yearly recertification. The Communication Centre Shift Supervisor is responsible for overseeing all operations within the Communication Centre and review calls for continuous quality improvement.
