121.1.1. The Community may, by by-law, order that it has competence in all or part of a field that is not mentioned in section 121 and that is within the competence of the municipalities whose territories are included in the Community’s territory, other than the imposition of taxes.
The secretary of the Community shall send a certified true copy of the by-law to each municipality for approval with 10 days of its adoption.
The council of each municipality shall decide on the approval of the by-law not later than 30 days after receiving the copy, failing which the approval is deemed to have been given.
The by-law must be approved by the Minister, who shall fix the date on which it comes into force. The Minister may approve the by-law only if it has been approved, in accordance with this section, by at least two-thirds of the municipalities, including Ville de Montréal.
