A History Worth remembering…

In honour of #opendataweek2026

A recent conversation about the “early days” of Toronto Open Data sent us down memory lane. When you’re busy building for the future, it’s easy to forget just how far the program has come. We realized that if we don’t document this journey, the institutional knowledge and the “why” behind our work might get lost in the shuffle.

For those new to the block, or those who have been with us since the first CSV was uploaded, this is a re-introduction. We aren’t just a portal; we are over a decade of policy shifts, community-led design, and a dedicated commitment to transparency.

At the heart of it all sits the Open Data Master Plan, the roadmap that transformed us from a technical project into a city-wide mandate. Here is the story of how Toronto Open Data evolved.

2009 – 2010 The Launch
  • Fall 2009: Official launch of Toronto’s first Open Data website.
  • 2010: Toronto co-founds the “G4” municipal group, setting a national standard for data sharing.
2011 – 2013 Policy Foundations
2015 – 2016 Modernizing the Vision
  • 2015: Formation of the Public Sector Open Data group.
  • 2016: A formal mandate from the City Clerk and CIO directs the team to “build a proper open data portal.”
2017 The Master Plan Co-Design SIGNIFICANT
2018 A Strategic Roadmap
2019 Visualizing Success
2020 – 2022 Stability & Integration
2023 The Centralization Mandate
2024 – 2025 15 Years & Global Impact
