Patrols an assigned area, responds to emergency and non-emergency calls, and enforces criminal and traffic law. Much of the work is talking to people in stressful situations, establishing what happened, and deciding what the law and service policy allow. Reports, disclosure, and court attendance take up a large share of the shift.

Provides emergency and urgent care outside hospital, assessing patients at scene, treating within a defined scope of practice, and transporting them where needed.

Gives pre-hospital care at a foundational scope of practice, responding to emergency calls, stabilizing patients, and transporting them to hospital.

Watches swimmers at a pool, beach, or waterfront, prevents unsafe behaviour before it becomes an incident, and rescues people who get into trouble.

Short course or on-the-job trainingPublic safety, defence and emergency response
Provides security and first response on a school, college, or hospital campus, balancing enforcement with student and patient support.

Short course or on-the-job trainingPublic safety, defence and emergency response
Staffs the first aid room on an industrial, construction, or remote worksite, treating injuries and illness on site and arranging transport when someone needs a hospital. The role also covers first aid records, equipment readiness, and prevention work alongside safety staff. Remote sites can mean long solo shifts with limited backup.
Short course or on-the-job trainingPublic safety, defence and emergency response
