Most registered psychologists in British Columbia have completed doctoral level study and supervised practice experience or the equivalent. Registered psychologists provide services to manage and enhance the cognitive, behavioural, emotional, interpersonal and physical functioning of individuals or groups of individuals, primarily by applying and using psychological assessment and intervention strategies, including psychometric testing and psychotherapy. As part of this work, psychologists also assess and diagnose behavioural, emotional, cognitive and mental disorders, but they do not prescribe medication here in BC. Registered Psychologists are regulated by the College of Psychologists of BC. You can find out more information here https://collegeofpsychologists.bc.ca/public/practice-of-psychology/
