18. The Société and the city may make an agreement respecting the application of municipal by-laws, the exercise of municipal powers and the supplying of municipal services in any part of the territory; such an agreement shall also apply to any part of the territory which the Société transfers by emphyteutic lease, or of which it obtains possession or ownership, from the time of such operation.
The city may also, under such an agreement, delegate to the Société any part of its powers respecting the territory covered by the agreement.
Such an agreement, to be valid, must be submitted for approval to the Minister of Municipal Affairs and to the Québec Minister.
If the Société and the city have been unable to agree on the terms of such an agreement, the Minister of Municipal Affairs, upon application by the Société but after having heard the city, may suspend, for such time as he indicates, the application of any by-law or the exercise of any power of the city in any part of the territory.
Every such agreement and every such decision of the Minister of Municipal Affairs shall be published in the Gazette officielle du Québec.
