Vice-President

Vice-President usually refers to a non-profit director who has the officer position of vice-president. The Societies Act does not require non-profits to have a vice-president. Therefore, the roles and responsibilities of a vice-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 vice-president
6.4 The vice-president is the vice-chair of the Board and is responsible for carrying out the duties of the president if the president is unable to act.
