Board of Directors

LHINs operate as not-for-profit Crown agencies governed by an appointed Board of Directors and are bound by a Ministry-LHIN Performance Agreement and Memorandum of Understanding with the Ministry of Health and Long-Term Care. Board members are appointed by an Order-in-Council for a term of one to three years, subject to a maximum of two terms (up to six years).

The role of the LHIN Board of Directors is to oversee, provide advice on and govern the strategic direction and priorities of the LHIN. The Board of Directors is accountable, through the Chair, to the Minister of Health and Long-Term Care for the LHIN’s use of public funds and for its performance results in the local health system.
