Technology and Data Quebec 3 Minutes Read · published February 11, 2026 Flag of Quebec · By Daniel Roy

Montréal, Quebec organisations that want to publish datasets to the city open data platform must follow municipal rules, metadata and licensing requirements and use the official portal for submission. This guide explains where to find the official rules, the typical fee and enforcement landscape, submission steps, appeals and contacts for municipal oversight.

Overview

Most dataset publication processes for the City of Montréal are managed through the city open data portal and the City’s open-data policy. Use the portal to create publisher accounts, upload datasets and accept reuse conditions.[1] For policy details and reuse conditions see the City information pages and the portal policy statements.[2]

Publish metadata and a clear licence before uploading files.

Penalties & Enforcement

The city’s public documentation about publishing datasets does not list specific fines or ticket amounts for publishing non-compliant datasets; where figures are absent this guide notes that the value is not specified on the cited page. Enforcement tends to focus on takedown requests, license compliance and administrative action rather than criminal penalties.

  • Enforcer: the Ville de Montre9al open data team or the City clerk’s office is the administrative contact for dataset publication and reuse compliance; specific enforcing office details are not specified on the cited page.
  • Monetary fines: not specified on the cited page.
  • Escalation: the portal documentation does not publish a tiered fine schedule for first, repeat or continuing offences.
  • Non-monetary sanctions: takedown orders, suspension of publishing privileges or requirement to correct metadata or licensing; exact measures are not specified on the cited page.
  • Inspections and complaints: complaints may be filed via the City contact channels listed in Help and Support / Resources below.
If you receive a compliance notice, act promptly and preserve records of corrections.

Applications & Forms

The city open data portal provides the submission interface and account tools for publishers; a distinct downloadable form for dataset publication is not quoted on the cited pages. For application steps and where to submit metadata see the portal guidance and the City open-data article.[1]

Required metadata, licences and technical requirements

Typical municipal requirements include descriptive metadata, source attribution, update frequency, file format and an explicit reuse licence. The exact metadata fields and licence options are specified on the portal’s dataset submission pages.[1]

  • Metadata: title, description, contact, update frequency and keywords.
  • Formats: machine-readable formats are preferred; check the portal for accepted file types.
  • Fees: the cited portal and City pages do not specify mandatory publication fees for organisations; fee amounts are not specified on the cited pages.

  • Incorrect licence or absent attribution - outcome: request to update licence or metadata.
  • Uploading unsupported file types or non-machine-readable data - outcome: request to reformat or re-upload.

How to appeal or request review

Appeals and review routes are administrative; the cited City pages do not provide exact statutory time limits for appeals related to dataset publication. If you receive a notice, follow the contact and complaint procedures provided by the City of Montréal and preserve records of submission and corrections.[2]

Action steps

  • Prepare metadata and choose a compatible licence before upload.
