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.
