Grade C — over 1%, or a tariff that cannot be standardized — shown as context or a range, never ranked. How the grade is set →

Standardized cost

Supply-only benchmark unavailable

Toronto's published residential tariff combines water and wastewater in a single per-cubic-metre rate. The statutory instrument is titled Water & Wastewater Consumption Rates. TWJ does not infer a potable-water component without an authoritative decomposition, so no supply price is published. The combined figure is published in full: it is established from a by-law, carries no recurring fixed charge and no tax, and reconciles against the City's own worked bill.

Does not exist

the instrument does not divide

Total Water Services is C$70.31 a month at the 2025 rate, from a by-law, with no recurring fixed charge and no tax. It is the supply figure that does not exist, and this city is in the Index to show the difference between the two kinds of blank.

Two metrics, two different kinds of blank. One figure is proved and published; the other is not withheld but absent, because no arithmetic can split a rate the by-law sets whole.

Where the water comes from

Surface

Toronto draws its drinking water from Lake Ontario through four treatment plants. Shares are trivially one category and no annual production figure with a year attached has been captured.

Why no numberToronto's published residential tariff combines water and wastewater in a single per-cubic-metre rate. The statutory instrument is titled Water & Wastewater Consumption Rates.

UWTI eligibilityNo — Structural non-comparability

Evidence statusVerified. The reason for withholding is itself established; it is a property of the tariff record and not of our work on it.

Reference connectionMetered residential service — no connection-size parameter — the residential tariff carries no connection-size parameter. Schedule 1 Ref 1 applies one rate to all metered consumers. Connection size appears in the code only in one-off installation fees, never in the consumption rate. Flat-rate and unmetered customers are priced per room and per fixture and are a different reference customer.
