Formula
Converts your daily water consumption in litres to cubic metres, then applies your city water and sewer rates. Most Canadian municipalities charge separately for water supply and wastewater (sewer) treatment, with sewer charges often equal to or exceeding water charges.
Canada FAQs
How much is the average water bill in Toronto?
The average Toronto household using 220 m3 per year (about 18 m3 per month) pays approximately $1,750 per year or $146 per month for combined water and wastewater. Toronto charges $4.23 per cubic metre for water and $3.72 per cubic metre for wastewater, totaling $7.95 per m3. Bills are issued every other month.
Why are Canadian water bills increasing so fast?
Canadian water rates have risen 5% to 8% per year in most cities, well above inflation. This is primarily due to aging infrastructure that needs replacement. Canadian municipalities face over $100 billion in deferred water and wastewater infrastructure upgrades. Cities are raising rates to fund pipe replacements, treatment plant upgrades, and stormwater management systems.
Which Canadian city has the cheapest water?
Among major cities, Ottawa has some of the lowest rates at $3.75/m3 combined (water plus wastewater). Montreal historically had very low rates due to minimal metering, but is transitioning to volumetric billing. Calgary ($5.23/m3 combined) and Vancouver ($6.33/m3 combined) fall in the middle, while Toronto ($7.95/m3 combined) is among the most expensive.
What is the wastewater charge on my water bill?
The wastewater charge covers the cost of collecting and treating sewage. In most Canadian cities, you are charged for wastewater based on the amount of water you consume, since nearly all water entering your home eventually goes down the drain. In Toronto, wastewater adds $3.72 for every cubic metre of water consumed, nearly doubling the effective water rate.
How much water does the average Canadian household use?
The average Canadian household uses 200 to 300 cubic metres per year, or approximately 550 to 820 litres per day. This translates to about 200 litres per person per day. Water usage is higher in summer due to lawn watering and pools. Households with water-efficient fixtures use 30% to 40% less, saving $500 to $700 per year in cities like Toronto.
Does my water bill include stormwater charges?
Many Canadian cities now charge a separate stormwater fee. Calgary charges $10.28 per month based on property lot size and impervious surface area. Kitchener, Mississauga, and other cities have introduced similar fees. Toronto does not yet have a separate stormwater fee but is considering one. This charge funds stormwater management infrastructure to prevent flooding and protect waterways.
How can I reduce my water bill in Canada?
Install low-flow showerheads (save 30 to 40 litres per shower), dual-flush toilets (save 10 litres per flush), and front-loading washers (save 50 litres per load). Fix leaky faucets, which waste 10 to 20 litres per day. Reduce lawn watering with drought-resistant landscaping. These measures can cut water use by 30% to 40%, saving $500 to $700 per year in Toronto.
