Volume-based water pricing means that people pay for the water they consume. Water volume is calculated in cubic meters using water meters that provide the city with data on water consumption in each non-residential building.

Montréal opts for volume-based pricing by progressive blocks, meaning that the rate increases with each consumption tier.

Bills based on the volume of water consumed are sent the following year. 

The following rates will be applied for 2025 water consumption billed in 2026: 

• 0 to 1,000 m³: $0 per m³ 
• 1,000 m³ to10,000 m³: $0,105 per m³  
• 10,000 m³ to 100,000 m³: $0,215 per m³   
• 100,000 m³ and more: $0,655 per m³  

If part of the building is for residential use, a volume of 225 m³ per dwelling is deducted from the total annual consumption.

This ecofiscal measure is separate from the special water tax shown on your yearly property tax bill.

Owners of non-residential buildings with two residential dwellings will see their 2025 bill for the 2024 water consumption calculated as follows:

It is possible to access data from the meter(s) attached to your building to track its water consumption. The meter is generally located inside the building, near the main water inlet. All you need to do is lift the cover to view the number shown.

Reducing water consumption in a building has a direct impact on billing. Examples of best practices to adopt include repairing leaks and defective plumbing fixtures, reducing watering, and replacing any prohibited cooling appliances that use drinking water.

This ecofiscal measure aims to promote environmentally friendly behaviors, while ensuring users contribute to the costs of water services in proportion to their usage. 

The new revenues thus generated will be earmarked for water management activities.
