If you do not belong to a union, this page is for you! Find out how you can become an ONA member, and have the protection and support you need in your workplace. If you are a current ONA member, update your contact information.

We are Ontario’s nurses and health-care professionals.

Founded more than four decades ago by 85 independent nurses’ associations, the Ontario Nurses’ Association (ONA) provides expert services and professional representation to our members.

We are a membership-driven organization with strong local leadership, and members have a direct say in their provincial representatives.

We are a professional union with 68,000 members working in hospitals, nursing homes, home care, communities, public health, clinics, industry settings, family health teams, and community health centres.

Because we are a nursing and health-care professionals’ union, all of our resources are devoted to advancing the interests of registered nurses and health-care professionals. ONA brings expertise in representing nurses and health-care professionals assisting members in the following areas:

  • At the bargaining table negotiating collective agreements in which ONA leads the health-care sector for wages and working conditions.
  • Handling grievances and arbitrations. ONA has achieved many awards on behalf of members.
  • At licensing body hearings (such as the College of Nurses of Ontario).
  • Have access to our valued education programs, professional practice specialists, human rights and equity team, health and safety specialists, Workplace Safety & Insurance Board experts and much more.
  • Through the ONA benefits program that provides base long-term disability for members not covered through their employer, all members have critical illness coverage in the event of a life-threatening event, and much more.
  • Access to our legal assistance (LEAP) and malpractice programs that assist our members with legal and/or regulatory body issues.

Why join a union?

A union is formed in a workplace when workers agree to speak to their employer with one strong, collective voice. Together, you are part of a professional team your employer must listen to. The conditions of your employment – including wages, benefits and working conditions – are negotiated between relatively equal parties.

Will my employer find out that I signed an organizing card?

No. According to the Labour Relations Act, your employer will not know whether or not you have signed an organizing card. You cannot be fired, disciplined or treated differently for participating in union activity. You are exercising your democratic right!

How does voting in my workplace work?

When at least 40 per cent of employees sign union cards, the union can submit an application to the Ontario Labour Relations Board. A week later a vote is held. With 50 per cent plus one of the vote in favour, the union becomes the legal representative of a group of employees.

What do my ONA dues cover?

The many services and representatives that ONA provides are funded by the dues that members pay. Dues are paid once a month through payroll deductions. Most of your dues are tax deductible. The dues rates can be found here.

If you are a non-union health-care professional and are interested in joining ONA, or want more information about the benefits of joining, please contact one of our Provincial Organizers by phone at 1-800-387-5580 (ask for Organizing) or by email at
