The Mission of Our School
The Mission of the York Region District School Board is that "we unite in our purpose to inspire and prepare learners for life in our changing world community."

The foundation of Sir William Mulock Secondary School is built upon four cornerstones to support the Board's Mission. These cornerstones are: Academic Excellence; Character Education; Communities – Local and Global; and Mental and Physical Well-being.
