522. When all the members of the Council have been designated or appointed in accordance with section 498, they shall meet to elect from among themselves a president and a vice-president. The members of the Council shall be called, for that purpose, by the director general by a special notice of at least three clear days, served in accordance with sections 286 and following.
Until the election of the president, the sitting at which such election must be held shall be presided over by one of the members of the Council, to whom section 526, however, does not apply.
If the election of the president and the vice-president or of either of them is not held at the first sitting after the calling or within the thirty days after such sitting, or if, thirty days after all the members have been designated or appointed, no call to hold such election has been made, the Minister may designate the president and the vice-president or either of them from among the members of the Council.
The term of office of the president and the vice-president shall be the same as that of their term as members of the Council. Subject to section 502, they shall remain in office, however, until chosen again or replaced.
Any vacancy in the office of president, vice-president or member of the executive committee shall be filled by the members of the Council within thirty days following the vacancy or, after such delay, by the Minister.
