118.2. An expenditure incurred by Ville de Québec or Ville de Longueuil in the exercise of an urban agglomeration power is financed by the aliquot shares paid by the related municipalities of the urban agglomeration concerned.
The first paragraph does not prevent the central municipality from financing such an expenditure by revenue from a source other than a tax or a compensation. The only mode of tariffing that may be provided for by the central municipality for that purpose is a fixed amount referred to in subparagraph 3 of the second paragraph of section 244.2 of the Act respecting municipal taxation (chapter F-2.1) or an amount exigible in the same manner as a subscription.
