President

President usually refers to a non-profit director who has the officer position of president. The Societies Act does not require non-profits to have a president. Therefore, the roles and responsibilities of a president depend on the non-profit's bylaws. 

Many non-profits have adopted model bylaws, such as Schedule 1 of the Societies Regulation. Schedule 1 states:

Role of president
6.3 The president is the chair of the Board and is responsible for supervising the other directors in the execution of their duties.
