Are you a mobile app developer interested in working with 311 Toronto and the Open311 standard? Please review the information below and then contact us at to receive additional information about our mock-up solution, which can be used in the development and testing of your application.

311 Toronto Mock-up Solution and Testing

311 Toronto has a mock-up solution for 3rd party developers to test their apps against 311 Toronto’s implementation of the Open311 API. This mock-up provides a set of fixed test cases to test the submission of a service request as well as providing status and location information for the test cases for potholes and graffiti.

If you’re interested in working with 311 Toronto to implement and develop applications using the Open311 standard and/or to test applications using the mock-up solution, please e-mail

Note: You do not need an API key to test your app with the mock-up solution.

Authentication of Completed Apps

Once your app is completed and tested using our mock-up solution, you are ready for the next step. At that time you can request an API key to begin the process of having your app authenticated for use with the City’s Open311 API. A production API key is required for a mobile app to submit service requests. 311 Toronto will contact you with further information once you have submitted an API key request.

Please note that you will need to review and agree to our “Technical and Operational Requirements” and the “Open311 API Terms of Service”, which are included in the request form.

We will, however, list the available apps on our website alphabetically with links to the 3rd party developer websites. The City is planning to promote the Open311 channel further in spring of 2012 through advertising and other methods.

311 Toronto does not provide QA support for any 3rd party apps. Any questions can be addressed by e-mail to
