What The Ontario Nurses’ Association does
The Ontario Nurses' Association (ONA) is a non-profit professional union founded in 1973 and headquartered at 85 Grenville Street, Toronto. Self-described as Canada's largest nurses' union, ONA represents over 68,000 registered nurses, nurse practitioners, and allied health-care professionals, plus 18,000 nursing student affiliates, working across Ontario hospitals, long-term care facilities, public health units, home care, community health centres, clinics, and industry. Its core service is collective bargaining and contract enforcement across provincial sectoral agreements, supplemented by a member portal (Access ONA), benefit programs, pension support, professional liability insurance, legal assistance, scholarships, and an eLearning catalogue.
ONA is funded entirely through membership dues collected via employer payroll deductions, with dues also extended to new bargaining units won through certification. The union operates through a regional and local structure that delivers field-level member service and runs organizing campaigns to add new workplaces, with recent wins at Ontario Health atHome and Fairview Mennonite Home. Public positioning is shaped by advocacy campaigns such as Code Black & Blue (workplace violence), Nurses Talk Truth (anti-privatization), the F-Word digital magazine, and constitutional challenges to Bill 124 and the HLDAA. The organization is governed by an elected Board of Directors led by Provincial President Erin Ariss (elected May 2023) and CEO Andrea Kay, and is a member of the Ontario Federation of Labour and the Canadian Federation of Nurses Unions.
Technology is not a productized surface: the member portal, content channels, and educational tools are operational infrastructure rather than monetized offerings, and there is no disclosed AI/ML capability. Competitive position rests on statutory bargaining rights, membership scale, and a 50-year operating history rather than product differentiation.
