# Canada Energy Regulator > Canada's federal energy regulator (CER / Regie de l'energie du Canada), created by the Canadian Energy Regulator Act in 2019 to replace the National Energy Board. It regulates interprovincial and international pipelines and power lines, energy imports and exports, and frontier and offshore oil and gas. It publishes a broad, licence-clean, key-free open data estate and no developer platform: 83 datasets and 944 resources on the federal Open Government Portal, 23 anonymously queryable ArcGIS feature services it operates itself, and one OGC WMS 1.3.0 layer on the Federal Geospatial Platform. There is no OpenAPI, no API key, no rate-limit policy, no developer portal, and no route to any individual's energy usage or billing data — consumer energy data in Canada is provincial, and the only mandate is Ontario's Green Button regulation administered by the Ontario Energy Board. Generated by API Evangelist on 2026-07-27 from https://github.com/api-evangelist/canada-energy-regulator. The CER publishes no llms.txt of its own (https://www.cer-rec.gc.ca/llms.txt returns the site's soft-404 page). ## APIs - [CER ArcGIS Online Feature Services](https://services5.arcgis.com/vNzamREXvX2WcX6d/arcgis/rest/services): The one CER-operated machine-readable surface. 23 public FeatureServers, 25 layers, anonymous, no key. Includes CER pipeline systems (28 features), pipeline incidents (1,899), Alberta Energy Regulator pipelines (315,089), provincial pipeline status and type, oil and gas resource areas, refineries and the Western Canada Sedimentary Basin. Query with /{service}/FeatureServer/{layer}/query?where=1=1&f=json. - [CER Assessments Map Service](https://maps-cartes.services.geo.ca/server_serveur/rest/services/NRCan/CER_Assessments_EN/MapServer): Environmental and Socio-economic Assessments layer on the Federal Geospatial Platform, served both as ArcGIS REST MapServer and as OGC WMS 1.3.0. - [CER Open Data via the CKAN Action API](https://open.canada.ca/data/api/3/action): All CER tabular data, filtered with fq=owner_org:A3EE9522-882F-47B0-BA7D-83420DC8577C. Operated by Treasury Board of Canada Secretariat, not by the CER. Requires a browser-like User-Agent or a WAF returns an HTML rejection under HTTP 200. ## Specs - No OpenAPI, Swagger, AsyncAPI, GraphQL SDL or RAML document is published on any Canada Energy Regulator host.

The CER holds no meter, usage or billing data and regulates no distribution utility; that is a provincial head of power.
