Leadership and Governance

Board of Governors

HSC's Board of Governors are a group of experts from across a variety of industries who are committed to the successful stewardship of the College.
HSC’s Board of Governors is composed of individuals committed to the successful stewardship of the College. The role of the Board is to establish and direct policies for the College, oversee HSC’s financial affairs and appoint a Head of College, and conduct his/her review. The Board is strictly a policy board, not an operational board, leaving responsibility for day-to-day operations to the HSC administration team.
Members of the Board are widely representative of key school constituencies and are elected based on their demonstrated ability and desire to effect a positive direction for the College. Strengths in law, construction, finance, information technology, education, transportation and manufacturing all mesh together to form a Board that is active and committed to HSC. Terms for the Board comprise three years with the possibility of a maximum of three additional, consecutive one year terms.

The Board meets approximately 10 times a year, augmented by monthly sub-committee meetings in the areas of Finance, Governance, Audit, Nominations, Alumni and Parents’ Guild. Communication to parents and other stakeholders is through email, an appointed Parent Ambassador or Board-Parent information meetings. Direct questions can be sent to: chair@hsc.on.ca.
