Toronto Hydro
Toronto Hydro is the municipally owned local electricity distribution company (LDC) for the City of Toronto, delivering power to roughly 800,000 residential and business customers across Canada's largest city. It sits in the wires-and-meters layer of Ontario's electricity value chain — it does not generate power and it does not run the wholesale market (that is IESO) — so the only customer-facing data it owns is smart-meter consumption, billing and account data. Its API posture is a clean example of a mandate that produced an implementation but not a developer product — Ontario's O. Reg. 633/21 under the Electricity Act, 1998 compelled rate-regulated electricity and gas utilities to offer Green Button Download My Data and Connect My Data conforming to NAESB REQ.21 ESPI v3.3 by 1 November 2023, and Toronto Hydro runs both — customer-facing Download My Data and Connect My Data pages behind its account login, a published third-party terms-and-conditions document, and a live third-party onboarding portal operated by its platform vendor Savage Data Systems. But there is no developer.torontohydro.com, no docs. or api. subdomain, no published base URI, no OpenAPI, and no self-serve keys. Consumer data is available only to companies that apply, pass a connectivity test and sign the third-party terms; market and grid data are not published openly at all. Mandated, implemented, and completely gated.
Toronto Hydro is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Toronto Hydro is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
