The purpose of nursing regulation is to protect the public.
There is no national nursing licence in Canada. Rather, the regulatory bodies of each province and territory are responsible for overseeing the actions of their members. These bodies protect the interests of the public by ensuring that safe practice standards are being upheld. They are responsible for outlining expectations for nurses in their jurisdictions, fielding complaints from the public, supporting safe nursing practice and regulating licensure.
See a list of provincial/territorial regulatory bodies for each nursing designation.
