Average Water Bill in Toronto Is $1,118, Below 21 GTA Bills

An average Toronto household pays $1,118.47 a year for water. That is the City's own average household, three people using 230 cubic metres a year, priced at Toronto's 2026 rate of $4.8629 per cubic metre. So 230 x $4.8629 = $1,118.47. The same household in Georgina pays $1,911.00, and in Mississauga it pays $908.30. We priced that one household on every GTA municipality's 2026 water and wastewater rate sheet. The water is the same. The bill is not.

The same 230 cubic metres, priced in 25 GTA municipalities

Toronto publishes the usage figure this study runs on. Its MyWaterToronto tool says that in 2020 the average household of three used 230 cubic metres a year, which works out to 630 litres a day. A cubic metre is 1,000 litres, so 230 cubic metres is 230,000 litres.

We took that one household and ran it through 13 separate 2026 rate sheets, which between them cover 25 GTA municipalities. Every rate comes from the municipality's or region's own rate page, billing brochure or fee by-law. Each municipality is priced on its own billing period, so consumption steps and fixed charges land the way that municipality actually bills them.

Georgina is the dearest at $1,911.00. Mississauga, Brampton and Caledon are the cheapest at $908.30, and they tie because Peel Region bills all three on one rate sheet. That is a difference of $1,002.70 a year for the same water, because $1,911.00 minus $908.30 = $1,002.70. Georgina charges more than twice what Mississauga does.

Put that in monthly terms and it is easier to feel. Mississauga works out to $75.69 a month, since $908.30 divided by 12 = $75.69. Toronto is $93.21 a month. Georgina is $159.25, because $1,911.00 divided by 12 = $159.25. Two households using exactly the same water are $83.56 a month apart, and neither of them chose that.

One caution on that Georgina number. It is Toronto's household priced on Georgina's rates, not what a typical Georgina home is billed. The Town's own brochure puts the average Georgina water user at about 165 cubic metres a year, and 165 x $7.62 ($3.92 + $3.70) = $1,257.30, plus $158.40 of capital cost recovery ($39.60 x 4), so $1,257.30 + $158.40 = $1,415.70. Georgina households use less water than Toronto's average. They still pay the most per cubic metre of anywhere here.

Toronto sits fourth cheapest of the 25. Only Mississauga, Brampton and Caledon come in lower. The middle of the pack is $1,270.26, the Durham Region figure, and the 13th of the 25 totals when you line them up. Toronto is $151.79 below that median, since $1,270.26 minus $1,118.47 = $151.79.

The expensive end is one region. The five priciest are Georgina, King, East Gwillimbury, Newmarket and Whitchurch-Stouffville, and all five are in York Region. Aurora and Richmond Hill are next. York's lower tier towns buy their water wholesale from the Region and then add their own local costs, and each one sets its own retail rate.

The rate sheets get there by two different routes. Georgina charges $3.92 a cubic metre for water and $3.70 for sewer, so $3.92 + $3.70 = $7.62, the steepest per cubic metre charge any of the 13 applies at this level of use. King, East Gwillimbury and Newmarket charge roughly two thirds of that per cubic metre and put the difference into fixed charges instead. Both routes land in the same place on the bill.

Why your address decides more than your shower

Most GTA water bills have two parts. One is a charge per cubic metre for what the meter reads. The other is a fixed charge you pay whatever you use.

The fixed charge is the part people do not expect. It covers pipes, pumps, meter reading and treatment plants, and those costs do not fall when you take shorter showers. Peel Region puts it plainly: more than 80% of the cost of getting water into a home and wastewater out of it is fixed.

Twenty of the 25 municipalities charge one. Five do not: Toronto, Markham, Richmond Hill, Aurora and Vaughan bill only for what the meter reads. Vaughan sets a monthly minimum invoice charge of $18 for water and $21 for wastewater, which only bites on a very low bill. At 230 cubic metres a year, or 19.2 a month, the metered water charge alone is more than twice that minimum, so it never applies.

King shows what a fixed charge does to a bill

King is the clearest case. Its 2026 rate report sets a base maintenance charge of $48.82 for water and $69.87 for wastewater on every bill, and prints the combined charge as $118.68 a bill and $712.10 a year, a few cents under the two line items added together, so this article uses the Township's printed figures. A King household pays that before a tap is turned. Its Tier 1 rate is $5.03 per cubic metre for the first 49 cubic metres on a bill, which gives 230 x $5.03 = $1,156.90. Add the Township's own annual base and the year is $1,156.90 + $712.10 = $1,869.00. Council approved those rates on October 14, 2025.

That fixed charge is $712.10 out of $1,869.00, which is 38% of the bill. A King household that halved its water use would still pay it in full. A Toronto household that halved its use would halve its bill, because Toronto has no fixed charge at all.

East Gwillimbury charges a fixed amount twice over. Its 2026 schedule sets $24.85 a month for the water service and another $24.85 a month for the sewer service. So $24.85 + $24.85 = $49.70 a month, and $49.70 x 12 = $596.40 a year. Newmarket's basic charges work the same way at $19.27 plus $22.72, which is $41.99 a month and $503.88 a year.

Fifteen of the 25 do not set their own rate

Three regions bill water directly, and their lower tier municipalities have no rate of their own.

Peel Region bills Mississauga, Brampton and Caledon. Durham Region bills Pickering, Ajax, Whitby, Oshawa, Clarington, Uxbridge, Scugog and Brock. Halton Region bills Oakville, Burlington, Milton and Halton Hills. That is 15 of the 25 municipalities on three rate sheets, so a move within any of those regions changes nothing on your water bill.

The other ten set their own. Toronto runs its own water utility. The nine York Region lower tiers buy water and wastewater treatment from the Region and charge their own retail rate on top. Markham explains why the wastewater half is dearer: the Region charges Markham for both services whatever happens to the water, so filling a pool still carries a sewer cost.

That split is why the spread is so wide. Where one regional rate covers a whole region, neighbouring towns match. Where each town sets its own, they do not.

What these numbers leave out

These totals are water and wastewater only, for a standard residential meter. Five things sit outside them.

Stormwater is billed separately and is not counted here. Aurora charges $18.35 per unit a month, so $18.35 x 12 = $220.20 a year. Whitchurch-Stouffville charges $9.50 a quarter and Vaughan $70.78 a year for a low density home. Peel adds a City stormwater charge to bills for Mississauga and Brampton properties, and Richmond Hill bills stormwater on the water bill by land area.

Solid waste is not water. In Toronto the same utility bill can carry garbage and recycling charges, which is one reason a Toronto bill often looks larger than the water figure here.

Nothing is added for tax. Every figure is the rate as the municipality publishes it. Two of the 13 schedules say outright why no tax follows: Durham's marks its water and sewer rates as not HST applicable, and Vaughan's fee by-law marks its water and wastewater rates exempt.

Meter size matters. Every fixed charge above is the standard residential meter: 20 mm or smaller at Halton, 16 or 19 mm at Peel, 17 to 19 mm at Durham, under 1 inch at Whitchurch-Stouffville and under 1.5 inch at King. A larger meter costs more. Durham's schedule takes the monthly water service charge from $24.04 on a standard meter to $48.86 on a 25 mm one, so an oversized service can cost well above the figures here.

One more thing. A rural home on a private well and septic tank pays none of this. Durham Region says many of its rural residents are in exactly that position, and King's water and wastewater services run only in King City, Nobleton, Schomberg and Ansnorveldt.

How we worked it out

This is arithmetic, not a survey. Nobody was asked what they pay.

We used one usage figure, 230 cubic metres a year, and applied it to each published rate sheet on that sheet's own billing cycle. That matters where a rate has steps. Peel bills every three months, so a quarter is 57.5 cubic metres. The first 50 go at $1.1308 and the rest at $2.4321, giving 50 x $1.1308 = $56.54 plus 7.5 x $2.4321 = $18.24, or $74.78 a quarter. Times four that is $299.12. Peel charges wastewater on 85% of what the meter reads, so 195.5 x $1.4538 = $284.22. Service delivery is $48.09 plus $33.15, which is $81.24 a quarter and $324.96 a year. The three add to $908.30. That step is per quarter whatever your billing cycle. Peel's rate by-law applies the base rate to "the first 50 cubic metres of registered meter consumption in each quarter (3 months)" and the higher rate to everything above that, in each quarter. Only the service delivery charge has a monthly version.

Two municipalities publish enough to check the method against their own numbers.

Newmarket's 2026 fee schedule prints an average residential bill of $1,512 at 200 cubic metres a year. Our method gives 200 x $5.039 = $1,007.80 plus $503.88 of basic charges, which is $1,511.68, or 32 cents under. Halton Region prints a worked example: a 20 mm meter using 38 cubic metres over two months pays $40.67 x 2 = $81.34 plus $3.3441 x 38 = $127.08, a total of $208.42. That one reproduces exactly.

Rates change through the year, so dates matter. Toronto, Durham, Halton, Newmarket and King moved on January 1, 2026. Peel, Vaughan, Markham, Richmond Hill, Whitchurch-Stouffville, East Gwillimbury and Georgina moved on April 1, 2026. Aurora moved on May 1, 2026. Every figure here is the rate in force in September 2026.
