7. The Minister of Municipal Affairs may, upon an application, exempt a municipality having a population of under 20 000 from the requirement of dividing its territory into electoral districts, on the terms and conditions he determines, and he may withdraw the exemption in the same manner.
The exemption ceases to have effect where the municipality is again required to divide its territory into electoral districts because its population has reached 20 000 or because it has submitted itself to the requirement.
The Minister shall publish notice of the exemption, of its withdrawal or of the cessation of its effect in the Gazette officielle du Québec and transmit a copy thereof to the Commission de la représentation.
