73.For the purposes of sections 123 to 137 of the Act respecting land use planning and development (chapter A‐19.1), and notwithstanding the third paragraph of section 123 of that Act, a provision likely to lead to the adoption of a separate by-law which, by reason of section 136.1 of that Act, must be submitted for approval to the qualified voters of the whole territory of the city is not a provision making the by-law a by-law subject to approval by way of referendum.
