Publishing third-party data


The Open Data Portal typically hosts data created by and/or owned by the City. However, there may be cases where hosting third-party data creates value for City of Toronto residents and businesses.

For instance, data about the City of Toronto’s Free-Floating Car-Share program, including locations of stations and usage, is provided by participating car-share companies to Transportation Services. That data can then be used by residents to better understand the efficacy and impact of the program.

In order for third-party data to be considered for hosting on the portal, the following criteria should be met:

  • A division has an existing relationship with a data partner and is using their data in a way that meaningfully contributes to City decision-making or service delivery.
  • The division believes that having their partner’s data accessible on the portal would streamline or add value to their operations.
  • The data is not readily available, or available only in a limited form, elsewhere.
  • The data is determined to be of interest or utility to the public.
  • The external data partner is open to having their data hosted on the portal and can commit to regularly updating and maintaining the data.
  • The data does not contain personal, personal health or confidential information and is able to be shared publicly by the City, according to all relevant laws and policies.

If a division is interested in hosting third-party data on the Open Data Portal, they should contact the Open Data Team.
