The Emergency Medical Services (EMS) is a service dedicated to providing the highest level of medical care outside of the hospital. This includes the transport of people or patients to care facilities that have illnesses or injuries. The EMS system varies from community to community. However, the general system and principles of EMS are the same in each province and territory.
Generally, EMS services should be called in all situations where the patient appears unwell, or the medical issues are beyond the scope of basic first aid training. It is better to exercise caution in first aid situations, if you are ever unsure, it’s better to call 911.
