Who we are 

Our aim is to protect workers and their communities from occupational disease, injuries and illnesses. We strive to address occupational hazards, to promote the social, mental and physical well-being of workers and their families.

Our goal is to accomplish this by identifying workplace factors that damage the health and welfare of all workers. This is through the distribution of occupational health, hygiene, and ergonomic information to increase knowledge among workers, employers and the general public. 


Ergonomics can be defined as fitting the job to the worker. Not all workers are the same size and everyone has limits. Ergonomics aims to design workstations, work processes, equipment, and tools to fit you. As a worker, it is important that you know how to adjust your workstation to suit your needs. Our services offer ergonomic resources in the form of appsergonomic assessment tools as well as a vast library of information available on our website. We also offer to send one of our highly skilled ergonomists to your workplace for an onsite assessment. For more information please contact ask@ohcow.on.ca

Occupational Hygienists

Our Hygienists look at the chemical,  biological (i.e. mould) and physical (i.e. noise) hazards that can lead to the development of diseases and develop strategies to reduce these hazards including engineering and administrative controls such as ventilation or noise control measures.

Occupational Health Nurse

OHCOW Nurses can help the workplace with the introduction of medical surveillance programs, lifestyle/wellness programs, and conducting hearing screening. The staff work together using an inter-disciplinary team approach to health and safety concerns.  By accomplishing this, OHCOW has been able to address the needs of workplaces in our catchment area. 

Our clinics 

For over 25 years, OHCOW has been a valuable injury and illness prevention resource for the workers and workplaces of Ontario.  The first clinics, proposed by the Ontario Federation of Labour (OFL) and funded through the Ontario Ministry of Labour (MOL), were founded in Hamilton and Toronto in 1989.  Expansion to Windsor, Sudbury, Sarnia, Thunder Bay and more recently Ottawa occurred over the next 20+ years.  

Staffed by an inter-disciplinary team of nurses, hygienists, ergonomists, client service coordinators, administrators and contracted physicians, each OHCOW clinic provides unique, comprehensive occupational health services, all free of charge: 

  • Inquiry service to answer work-related health and safety questions  
  • Clinical services to provide evidence-based technical and medical reports determining work-relatedness for individuals
  • Group service providing exposure or health-based prevention consulting for workplaces, health and safety committees and groups of workers 
  • Outreach and education to increase awareness of health and safety issues, foster dialogue and promote prevention strategies. 
  • Research services to better understand hazards, illness incidence and control effectiveness.

OHCOW is governed by an eighteen person volunteer Board of Directors drawn from Labour and Community Stakeholders. Each clinic maintains a Local Advisory Committee to be responsive to community needs. Leadership of OHCOW is comprised of the Chief Executive Officer, Chief Operating Officer, four Executive Directors and the Manager of Accounting. Funding and direction is provided from the Ministry of Labour Prevention Office through a Transfer Payment Agreement.  The Provincial Office, in Toronto, supports the activities of the clinics, liaises with the Ministry and regulators and manages Finance, HR & IT.
