The College of Nurses of Ontario (CNO) has the authority to register NPs in the Anaesthesia specialty. We currently have no one registered in this category

At CNO, a “member” is any individual who has a valid Certificate of Registration and is allowed to use the protected titles “nurse,” “Registered Nurse (RN),” “Registered Practical Nurse (RPN)”, “Nurse Practitioner (NP)” or “Registered Nurse (RN), non-practising” and “Registered Practical Nurse (RPN), non-practising”.
