Ontario Health Regions

Ontario Health has six regional teams that manage the province’s health system.

Ontario Health regions work with local community and health care partners to improve:

  • the patient experience
  • population health and health equity for people in Ontario
  • front-line provider experience

We do this through:

  • system planning and managing system integration
  • allocating funds to achieve the best possible health outcomes
  • monitoring health care performance

Our Approach

The regional teams include health care planners and financial experts who work with providers and partners to manage health care delivery in our communities. Using a population-based health planning approach, the regions help ensure that the people we serve have access to the right care and services when they need them.

Funding

Improving the system takes planning and funding. We provide opportunities for health service providers to submit proposals and expressions of interest for planning, funding and additional resources to help improve the patient and provider experience.

Get Involved

Our patient and family advisory councils (part of the Patient and Family Advisors Network) are made up of patients and caregivers in each region.

Council members have valuable first-hand experience and insights into the local health care needs, what’s currently working and how to improve the system to continue to meet future needs of our community. Diversity and geographical representation matters.
