Water charges shared by usage

Summary#

Montréal city council unanimously approved a position supporting adoption of the 2026 bylaw on drinking-water charges, the Règlement concernant la quote-part tarifaire pour l'alimentation en eau potable (exercice financier 2026). The bylaw would set how the agglomeration’s drinking-water operating costs are divided among the linked municipalities, using water consumption. The agglomeration council makes the final decision at a later meeting.

  • City staff say the current arrangement, based on a 2016 agreement, divides costs for producing and distributing drinking water according to each municipality’s consumption.
  • For 2026, an initial bill would use a rate of $0.3324 per cubic metre and estimated consumption.
  • Each municipality’s final charge would be adjusted using actual water use and actual costs for water supply, treatment and distribution.
  • The bylaw would also set payment procedures for these charges.

What it means for you#

  • Linked municipalities: They would pay a share of agglomeration drinking-water operating costs based on their water consumption. The initial amount would be an estimate, followed by a final adjustment.
  • Residents and businesses: The materials do not say that this decision directly changes individual water bills, service rules or water use.

Money#

City staff estimate the charges would bring the agglomeration $121.7 million in revenue.

  • Linked municipalities would be billed provisionally using the stated rate and estimated consumption; final charges would reflect actual costs and consumption.
  • The materials give no separate cost estimate for administering the billing or adjustment process.

What is unclear#

  • The bylaw text is not included, so the detailed payment procedures and calculation rules cannot be verified.
  • The materials do not give each municipality’s estimated charge or explain when and how final adjustments would be billed.

Case for#

  • A possible argument for the approach is that municipalities’ shares would track their water use, rather than the default allocation method based on fiscal capacity.
  • Adjusting charges to actual costs and consumption could make the final allocation reflect what the agglomeration spent and how much water each municipality used.

Case against#

  • The provisional bills rely on estimated consumption and would later be adjusted, so municipalities may not know their final charges at the outset.
  • A consumption-based allocation means municipalities using more water would pay more, even if their fiscal capacity differs.
