To answer your question, we would refer to the NS Regulated Health Professions Act and the Psychology Regulations. If the services to the public in NS infringe on the Regulated Health Professions Act and the Psychology Regulations then we would require registration here.
Typically, a violation would result from one using a title or description that identifies the direct provider as a psychologist or the services as psychological.
Ultimately if the services are not marketed using terms that contain the word psychology, psychological or a derivative, and the practitioner is accurately identified to the public with a title that is not in contravention of the Act, then this will avoid any infringements and the need for registration in NS. However, the NSRP does not see the public as being protected if one’s practice is not regulated.
