NPs can work on their own and do not need to be supervised by a physician to practice. NPs have an autonomous scope of practice, but typically work in collaboration with physicians and other health care professionals. See the College of Nurses of Ontario’s (CNO’s) Practice Standard: Nurse Practitioners for more information at https://www.cno.org/globalassets/docs/prac/41038_strdrnec.pdf NPs are usually graduate-prepared RNs and are registered in the Extended Class by CNO. NPs work in a variety of practice settings including in the community, hospitals and long-term care and across age groups.
