57.4. If the revised RCM plan concerns part of the territory of a metropolitan community, the council of the metropolitan community must, within 60 days after it is sent a copy of the by-law establishing the revised RCM plan, approve the by-law if it is in conformity with the metropolitan plan or withhold approval if it is not.
A resolution withholding approval of the by-law must include reasons and specify which provisions of the by-law are not in conformity with the metropolitan plan.
As soon as practicable after the passage of the resolution approving or withholding approval of the by-law, the secretary of the metropolitan community shall, in the first case, issue a certificate of conformity in respect of the by-law and send a certified copy of the certificate to the regional county municipality or, in the second case, send the regional county municipality a certified copy of the resolution.
If the council of the metropolitan community does not resolve to approve or withhold approval of the by-law within the period prescribed in the first paragraph, the by-law is deemed to be in conformity with the metropolitan plan.
