The Ontario Energy Board (OEB) is the independent regulator of Ontario's electricity and natural gas sectors, licensing and rate-regulating roughly 60 electricity distributors, the province's transmitters, storage and generation licensees, unit sub-meter providers, energy retailers and gas marketers, and Enbridge Gas. It sits above the wires-and-pipes layer of Canada's largest provincial energy market — it does not own assets, does not run the wholesale market (that is IESO) and holds no customer meter data — so everything it publishes is regulatory, rate and utility-performance data rather than consumption data. Its API posture is the sharpest consumer-versus-market split this series has recorded in Canada. On market data it is genuinely open — an Open Data programme launched September 2022 under Ontario's Digital and Data Directive publishes 40 datasets - 198 individual files, verified by crawl on 2026-07-27; the programme's own earlier count was 18 - as anonymous, key-free XML, XLSX and GIS files under the Open Government Licence – Ontario, covering every open application before the Board (updated daily), current electricity and natural gas rates, distributor service-territory boundaries, the distributor performance scorecard, consumer complaints, and thirteen Reporting and Record-keeping Requirements (RRR) filings series going back to 2015. On consumer data it publishes nothing at all, because it holds nothing — it is instead the supervisor of the consumer-data mandate. Ontario is the only Canadian jurisdiction with a compulsory energy-data-sharing rule — O. Reg. 633/21 (Energy Data) under the Electricity Act, 1998 required rate-regulated electricity and natural gas utilities to implement Green Button Download My Data and Connect My Data to NAESB REQ.21 ESPI v3.3 by 1 November 2023 — and the OEB is the body that ran the consultation (EB-2021-0183), amended the Retail Settlement Code, collected quarterly progress reports and publishes the implementation status register naming 54 confirmed distributors and 6 extensions. There is no developer portal, no OpenAPI, no API key and no signup — just files, plus an undocumented but live JSON output on the regulatory document search.
Ontario Energy Board publishes 2 APIs on the APIs.io network: OEB Open Data and OEB Regulatory Document Search (RDS). Tagged areas include Energy, Canada, Ontario, Utilities, and Electricity.
Ontario Energy Board’s developer surface includes documentation, developer portal, support, engineering blog, authentication, changelog, and 22 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Energy & Utilities regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

description: The Ontario Energy Board's Open Data programme, launched September 2022 under Ontario's Digital and Data Directive
(2021) and expanded in October 2023 ("Open Data 2.0") and August 2024. A crawl of both pages of the programme index on
2026-07-27 found 40 datasets linking 198 individual files (the earlier round recorded 18 datasets), all directly downloadable,
anonymous, key-free files — no registration, no application, no rate limit and no terms click-through — under the Open
Government Licence – Ontario. The largest share is XML — the daily-refreshed register of every open application before
the Board, three monthly/quarterly rate files that back the OEB's own bill calculator, twelve annual electricity distributor
performance scorecard files (2013-2024), ten annual consumer complaint files, and thirteen Reporting and Record-keeping
Requirements (RRR) series covering system reliability, service quality, major event response, billing accuracy, LEAP low-income
assistance, customers and connections, labour, capital, supply and delivery, demand and revenue, utility characteristics
and regulated return on equity, each published as separate current, 2015-2021, 2023 and 2024 files. Distributor service-territory
boundaries ship as GIS ZIP archives for electricity and natural gas. This is not a query API — there is no base path,
no parameters, no pagination and no machine-readable contract of any kind. It is a set of stable, versioned, anonymously
fetchable files with a published guide for importing the XML into Excel. Verified live on 2026-07-27, every URL below
returning HTTP 200.

description: The OEB's public regulatory document search, serving every filing, decision, order, licence, code amendment
and piece of correspondence in the Board's case record. It runs on Micro Focus / OpenText Content Manager WebDrawer, and
the OEB links directly to parameterised query URLs of the form /CMWebDrawer/Record?q=CaseNumber=EB-2021-0183&sortBy=recRegisteredOn-&pageSize=400
from its own website — the licensed-companies list alone links hundreds of them. Fetched anonymously on 2026-07-27, this
surface also honours a `format=json` parameter and returns application/json — a Content Manager ServiceAPIModel payload
with Results, TotalResults, Count, HasMoreItems and typed Fields including CaseNumber, SIDocumentType, Applicant, EnergyType,
PrimaryApplicationType and DateIssued — while /CMWebDrawer/Record/{uri}/File/document returns the underlying PDF. IMPORTANT
— the OEB publishes no API reference, no base-URI statement, no query-syntax documentation, no OpenAPI and no terms for
this interface; the JSON output is default behaviour of the underlying WebDrawer product, not a product the OEB documents
or supports. It is recorded here because it was verified live and anonymous, not because it is an offered API. No key,
no signup, no rate-limit policy published.
