Open Data License change: FAQ

Updated: 8 September 2016

Open Data License change: FAQ

The City of Ottawa has implemented a new “Open Data Licence”, replacing the “Open Data – Terms of Use” that previously governed the usage and distribution of City of Ottawa data sets.

The Open Data License is based on version 2.0 of the “Open Government Licence – Canada” which was developed through public consultation and consultation with other jurisdictions. The only substantive changes in this licence are to replace references to the Government of Canada with the City of Ottawa, replace a reference to the Federal Privacy Act with a reference to the Ontario Municipal Freedom of Information and Protection of Privacy Act, and remove a reference to the Federal Court of Canada.

Q: What is the purpose of the Open Data Licence?
A: The Open Data licence governs the usage of data made available by the City of Ottawa through its Open Data platform. It establishes what users can do with the data, what their responsibilities are, and clarifies the exemptions that are not covered by the licence.
The licence helps ensure that Open Data can be as beneficial as possible to residents and businesses by providing an updated framework for using data.

Q: Why were the Terms of Use replaced by the Open Data Licence?
A: Replacing the Terms of Use with the new Open Data Licence allows the City’s Open Data program to simplify the usage, modification and distribution of the data provided through its Open Data platform. Essentially, the goal is to reduce or eliminate as many barriers as possible to the free and open use of data provided by the City of Ottawa.

Different terms of use and licences across jurisdictions make it difficult for users, researchers and developers to fully benefit from open data originating from various government sources. Creating a coherent licensing framework across the municipal, provincial and federal levels facilitates the combination of data sets to create useful analyses or applications.

Adopting a common licensing framework has been an objective of the Open Data program since the first year of its launch in 2010. The creation of the Canadian licence, its positive reception by the public and adoption by many jurisdictions now provides the City with this opportunity.

Q: What are some of the important changes in the Open Data Licence?
A: The Open Data Licence eliminates distribution and proprietary interest wording. Often, this is a barrier for users and businesses that utilize multiple organizational data sets in their applications. The license also adds versioning and definitions sections: versioning helps users know when changes are made to the licence; definitions help clarify terms and reduce ambiguity when using data governed by the licence.

Q: What is the impact to users who obtained data from the City’s Open Data program under the old Terms of Use?
A: Any data set(s) previously accessed under the Terms of Use will continue to be governed by those terms; however, as of 8 September 2016, all data sets accessed through the City of Ottawa’s Open Data website ( will be governed by the new licence. For example, if data set “x” was accessed before 8 September 2016, it is governed by the terms of use; if the same data set is accessed on or following 8 September 2016, it is governed by the new licence.

Q: Was there any cost to adopting this license?
A: There were no costs associated with the adoption of this license outside of staff time.

Q: How will we ensure that we remain consistent with the Canadian Open Government License?
A: Staff participate in several inter-jurisdictional Open Data working/knowledge sharing groups. Any update to the Canadian license will be discussed within these groups and provide opportunity to assess changes to Ottawa’s license.

Users are encouraged to familiarize themselves with the new Open Data Licence which can be found at

Open311 and third party apps

The City of Ottawa has adopted an open standard (Open311) that allows third party apps to communicate directly with our 311 technology. Open311 empowers citizens and allows cities to do more with less.

About the Open311 standard

Open311 is a set of technologies and standards for providing open, two-way communication around city service- and issue-tracking. More specifically, Open311 enables a web-based application programming interface (API) to connect with existing 311 systems. This permits applications to be built that interface directly with the city.

For more information on Open311 and the collaborative effort to create an open standard for 311 services, visit the Open311 website.

Select Service Requests of the following types are currently available:

  • Solid Waste
  • Roads Maintenance
  • Graffiti

Development process

Applications that are built using the Open311 GeoReport v2 Standard for the City of Ottawa should be tested using the following:​/

See our Developer Guidelines for more information.

In order to secure the City’s back-end systems, applications will require the use of an API key for every request in production.  In order to obtain an API key complete the registration form.

The City will review API Key Requests to ensure that developers have a privacy policy and have agreed to the terms and conditions of the City of Ottawa Open311 API Terms of Service prior to issuing an API Key.

Third party apps

The City does not endorse third party applications, guarantee that they will meet your requirements, that their use will be uninterrupted, that there will be no delays, failures or errors or omissions or loss of transmitted information resulting from their use, that no viruses or other contaminating or destructive properties will be transmitted by their use or that no damage will occur to your device  due to their use. You have sole responsibility for use of third party applications and you use them entirely at your own risk.

The City will not be liable to you or to others for any loss, damage or injury of any type caused or contributed to in any way by use of any of third party application and any problems or damages arising from use of third party applications are a matter exclusively between you and the application provider. You release and forever discharge the City from all claims arising from use of third party applications.

* Platform names are trademarks of the respective vendor.

Although the City has adopted the Open311 standard, anyone may continue to instead submit Service Requests directly to the City using the City’s online channel, or by calling 3-1-1.

If you have any questions regarding the City of Ottawa’s Open311 GeoReport v2, please contact Open Data.
