Ottawa Open Data Requests - Municipal Records & APIs

Technology and Data Ontario 3 Minutes Read · published February 11, 2026 Flag of Ontario

Ottawa, Ontario provides a public open data portal for machine-readable municipal records and APIs to support transparency and reuse. Start by searching datasets on the City of Ottawa portal and catalogue to see if the record is already published on the open portal open.ottawa.ca[1]. If the dataset or API you need is not available, the City describes how to request publication or request access through its Open Data program and licensing terms open data licence[2].

What this covers

This guide explains how to request machine-readable records and APIs from the City of Ottawa, the departments responsible, the forms or channels to use, expected timelines, and enforcement or appeal routes where the City’s open data commitments apply.

How to request machine-readable records or an API

  • Search the public portal for the dataset or API you need at the City catalogue.
  • If not available, prepare a clear description of the data fields, format desired (CSV, JSON, GeoJSON), frequency, and proposed licence or reuse needs.
  • Contact the City’s Open Data program or submit a publication request as directed on the City Open Data program page City Open Data[3].
  • If access concerns personal or sensitive information, the City follows MFIPPA and may require a formal access to information request under provincial rules.
Start with the portal search and dataset metadata before filing a request.

Penalties & Enforcement

The City’s open data pages describe responsibilities and licensing but do not specify administrative fines or monetary penalties for nonpublication on the public open data pages; such sanctions are not specified on the cited pages City Open Data[3].

  • Escalation: not specified on the cited page.
  • Non-monetary sanctions: not specified on the cited page; the City may use internal compliance, publication orders, or administrative directions where applicable.
  • Enforcer: the City of Ottawa Open Data and Open Government program, and the responsible data-holding department; contact details and submission channels are on the City Open Data page City Open Data[3].
  • Appeals/review: formal appeal routes or statutory time limits for refusal are not specified on the City open data publication pages; if a request involves access to personal information, appeals follow MFIPPA procedures (provincial process).

Applications & Forms

  • No distinct generic "open data" surcharge form is published; requesters are directed to the City portal and program contact instructions for publication requests or to file an access to information request under MFIPPA where personal information is involved.

Action steps

  • Search the open portal for the dataset or API.
  • If missing, prepare a publication request with dataset structure and desired format.
  • Send the request through the City Open Data contact channel or follow the portal instructions.
  • If access is refused and the matter involves personal information, consider MFIPPA access to information and appeal routes through the Information and Privacy Commissioner of Ontario.
If a dataset contains personal or exempt information, publication may be refused under privacy rules.

FAQ

Is there a fee for open data publication requests?
The City’s open data pages do not list a standard fee for publication requests; fees for formal access to information under MFIPPA may apply and are governed by provincial rules.
