Technology and Data Ontario 4 Minutes Read · published February 11, 2026 Flag of Ontario

Ottawa, Ontario maintains an open data program for publication and access to municipal datasets that supports transparency and reuse. This guide explains publication expectations, metadata and licensing references, and how to access Ottawa datasets via the city portal and API. It summarizes enforcement and administrative pathways, practical steps to prepare and publish data, and how to report issues or request exceptions. Wherever official specifics are available on City of Ottawa pages or the city data portal they are cited directly; where a particular penalty, fee, form, or time limit is not published on the cited page this guide notes that fact and points to the responsible contacts for next steps.

Publication requirements and metadata

Ottawa publishes datasets via the official City of Ottawa open data portal and maintains guidance on dataset publication, recommended metadata fields, and licensing terms on the municipal site and the data catalogue. To confirm accepted file formats, required fields and licensing, consult the City of Ottawa Open Data Program and the data portal API documentation linked below.[1] City of Ottawa data portal[2]

  • Required metadata: title, description, publisher, update frequency (as listed on portal or dataset page).
  • Preferred formats: CSV, GeoJSON, Shapefile, or API endpoints where offered.
  • Licensing: observe the City of Ottawa open data licence or stated dataset licence on the portal.
Always check the dataset landing page for dataset-specific licence and update notes.

API access and technical endpoints

The City of Ottawa data portal exposes datasets and API endpoints for programmatic access; many datasets support CKAN-style API calls and direct resource downloads.
