Leadership & Governance

Our governance model is designed to ensure effective oversight and strategic direction for CMHA Toronto. 

Board of Directors 

The CMHA Toronto Board of Directors is responsible for overseeing the organization's strategic direction, financial management, and risk management. The Board is made up of volunteer members who have diverse backgrounds and expertise in areas such as finance, law, and mental health. 

The Board delegates the day-to-day management of the organization to the Chief Executive Officer, who with the Senior Leadership Team, are responsible for ensuring that the organization's programs and services are delivered effectively and efficiently. 


The CMHA Toronto governance model also includes a number of committees that are responsible for providing advice and support to the Board and Chief Executive Officer. These committees include the Finance and Audit Committee, the Governance Committee, Quality Improvement Committee and the Human Resources Committee.
