We Represent


We are proud to be the largest and most-respected union of registered nurses in Canada. Why? Because we focus exclusively on improving and enhancing working conditions for registered nurses who provide quality care to patients. We are known leaders in collective bargaining, and a prominent voice in advocacy for better care.

Everything we do is about health care; always has been, always will be.

The Ontario Nurses’ Association (ONA) is the union representing 68,000 registered nurses and health-care professionals as well as 18,000 nursing student affiliates. ONA is the voice of Ontario’s knowledgeable and experienced nurses.
