Open Data

The Digital Markham Strategy is a vision of the City's future in 2025. Part of this strategy includes the City of Markham's Open Data initiative and the creation of an online Open Data Catalogue that's accessible to the public.

Open Data is data that is made freely available to the public so that it can be used, modified and shared by anyone and for any purpose.

The Open Data program is intended to support innovation and economic development, create a better informed public, enhance customer service, realize efficiencies, and support value-added benefits from the community.

Imagine a world where developers are able to use open data to create transportation apps so users can view their own personalized planning tool for public transport, or through using open data and predictive analytics, emergency services can track buildings at highest risk of fire. Imagine no more because cities and citizens around the world are already doing this and more. The possibilities of Open Data are numerous, and we are just on the cusp of a new, innovative, digital journey here at the City.

Any data that's generated or collected by the City of Markham is a potential candidate for Open Data release, subject to privacy and confidentiality considerations. The City will not release personal or confidential information, or provide ways to identify individuals as part of the public datasets. All datasets released through Open Data will fully comply with the Municipal Freedom of Information and Protection of Privacy Act (MFIPPA).

Open Data presents a number of potential opportunities and benefits including but not limited to:

  • Improved government transparency and accountability,
  • Enhanced services to citizens and businesses,
  • New opportunities for providing services using businesses or individuals as an intermediary in the service delivery process,
  • Fostered entrepreneurship through innovative use of government data,
  • Optimized processes via streamlined access to data and less external Freedom of Information and data requests; and
  • Development of third-party applications utilizing government data.

The City of Markham's Open Data program is ever-changing as it continues to evolve. Please note that new data will be added to our Open Data Catalogue on a regular basis.

We hope you'll find our Open Data program informative and useful. If you have any questions, comments, or would like to request a specific dataset, we'd love to hear from you at

Open Data Catalogue

Our open data catalogue offers users the ability to interact with and easily download the data.
