REGULATING PSYCHOLOGISTS IN NOVA SCOTIA SINCE 1980
Category: Registrant

To answer your question, if you are a registered psychologist in Nova Scotia and move out of the Country, you can still maintain your Nova Scotia registration (i.e., you can be registered in more that one jurisdiction during the same timeframe). This would allow you to see current clients in Nova Scotia via telepsychology. However, if you need to treat clients outside of NS, you would need to contact the respective jurisdiction where those clients will be located, as normally the jurisdiction where the client is located is seen as having jurisdiction over the practice of psychology.
