Ontario Schools of Medicine undergraduate medical education programs enroll medical students who have registration and/or previous employment in other areas of health care. To support financial obligations as students, undergraduate medical learners may seek temporary or seasonal employment in their registered health professional roles. These roles may overlap with learning in clinical environments. In addition, students may undertake employment opportunities as unregulated workers. This guideline will direct decision making for a select group of students involved in clinical learning at a health care facility where they are/have been employed (full or part time) as a health care worker.
