5. Any municipality that is not required to divide its territory into electoral districts may submit itself to that requirement by by-law of its council passed by a two-third majority of its members, which must, under pain of nullity, come into force during the second calendar year preceding that in which a general election must be held.
As soon as practicable after the coming into force of the by-law, the clerk or the secretary-treasurer shall transmit a certified copy thereof to the Minister of Municipal Affairs and to the Commission de la représentation.
