Sub-regions: Bringing local even closer to home

What is a sub-region? 

A sub-region is a smaller geographic planning region within the South West LHIN that will help the South West LHIN to better understand and address patient needs at the local level. The sub-regions have existed informally within South West LHIN for many years and they are have been formalized.

Why are they needed? 

By looking at care patterns through a smaller, more local lens, the South West LHIN will be able to better identify and respond to community needs and ensure that patients across the entire LHIN have access to the care they need, when and where they need it. This includes the needs of Francophone Ontarians, Indigenous communities, newcomers and other individuals and groups within the South West LHIN whose health care needs are unique and who often experience challenges accessing and navigating the health care system.

Where are the sub-regions in the South West LHIN?

We have identified five sub-regions that follow County boundaries: Elgin, Oxford, London Middlesex, Huron Perth and Grey Bruce. 

How were they identified? 

The sub-regions were identified based on the strong history of collaboration within the LHIN, consultation with local health service providers, and patient referral patterns, including information that was available when developing the Health Links coordinated care planning approach to better serve residents with high care needs. 

What’s happening now? 

Each sub-region has a strong history of planning together, sharing resources and training opportunities, and working on common issues. While a sub-region approach to health service planning and evaluation has been in place for several years, the South West LHIN is now formalizing the sub-region geographies to allow for more integrated planning at the local level and to support provincial priorities related to the Patients First: Action Plan for Health Care.
