About Ontario Occupational Health Nurses Association

For nearly 50 years, the Ontario Occupational Health Nurse Association (OOHNA) has been the voice for Ontario’s Occupational Health Nurses.

OOHNA’s mission is to support the long-term sustainability, professionalism and growth of Ontario’s Occupational Health Nurses. On behalf of our vibrant members, we strive to build cutting-edge educational programs, member benefits including our amazing professional liability insurance program and peer-to-peer networking and relationship building.

Through focused education programs and services, OOHNA enables OHNs to grow, learn, get connected and keep workers safe and well here in Ontario.

We are proud to represent the majority of OHNs in Ontario and are working diligently to ensure the next generation of Nurses in Ontario are well-informed on the benefits of being an OHN.

In 2009, Amy began an uncertain search for a career outside of acute care at the hospital. She was then hired to work at a busy industrial plant. She changed positions to a new company in 2012 and now work in her own clinic covering two manufacturing sites. In her spare time Amy is busy looking after my young son and husband. Amy also enjoys time as a family in the great outdoors at our cottage.
