85.4. Despite the Municipal Aid Prohibition Act (chapter I-15), the municipality may, by by-law, adopt a revitalization program for that part of its territory designated as the “centre” or “central sector” pursuant to a special planning program. It may, on the conditions it determines, make an order granting a subsidy for work consistent with the revitalization program. The amount of the subsidy must not exceed the actual cost of the work. The municipality may establish classes of immovables and classes of work, and combine them, for the purposes mentioned in the first paragraph. It may establish different conditions for different classes and combinations of classes and order that a subsidy be granted only for one or some of them.
The municipality may have recourse to the second paragraph in a different manner for different sectors of its territory that it determines.
Furthermore, a municipality whose territory includes several “centres” or “central sectors” under a special planning program may have recourse to the second paragraph in a different manner for each of them.
