​​The Mental Health and Addictions Hospital Committee provides the OHA with strategic advice to inform its advocacy on issues affecting hospitals that provide mental health and addictions (MHA) services. The committee is composed of Chief Executive Officers (CEOs) of hospitals that provide MHA services, through invitation by the OHA. Committee membership is based on MHA volume in hospitals and reflects regional representation across the province. The committee aims to foster high-value engagement that keeps members well-informed and facilitates the balanced flow of information among committee members, OHA members, system stakeholders, and government. ​
