We are Canada’s largest nurses’ union. Our members provide care in hospitals, long-term care, public health, clinics, the community and industry. Together, we push for reforms and fight for better workplaces. We don’t settle because a lot is at stake––who we are, where we work and who we work for.
We are a platform for local action. We fight against unfair and unsafe treatment, policies and government decisions that impact your ability to provide safe and quality care. We negotiate and enforce your contracts, offer benefits and insurance, provide tailored education and development opportunities and more.
In times of universal deceit, telling the truth is a revolutionary act.
We recognize and commemorate the intergenerational harm that residential schools caused to Indigenous families and communities, and honour those who have been affected by this injustice.
Register for demand-setting meetings for our upcoming contract negotiations.
HENSALL, ON, September 9, 2026 – Registered nurses (RNs) providing care to residents of Queensway Long-Term Care Home have unanimously voted to join nurses and health-care professionals across the province in using their collective voice to improve their working conditions and care for all Ontarians by becoming the newest members of the Ontario Nurses’ Association (ONA).
Toronto, ON, September 3, 2026 — The Ontario Nurses’ Association (ONA) is raising serious safety concerns about more than 215 registered nurse (RN) positions cut across Ontario hospitals in the past two months alone. This is part of an escalating trend of hospitals cutting RN positions, often replacing them with other health-care professionals amid provincial underfunding. This can put patients at risk, as different roles do not have the same education, training and skill to respond to unstable patients.

TORONTO, ON, August 18, 2026 – The latest arbitration decision released for registered nurses (RNs), registered practical nurses (RPNs) and health-care professionals working in Ontario’s for-profit nursing homes is yet more evidence that the system is broken and should be scrapped, says the Ontario Nurses’ Association (ONA).
