How we use third-party content
Zoned uses open-source software, open data, and commercial services under their respective licences and terms. Where a licence requires attribution (such as the Open Database Licence for OpenStreetMap, the Open Government Licence — City of Ottawa, or the Open Government Licence — Toronto), we provide it here. Where a licence requires redistribution notices or source access, we make those available on request.
Zoned’s interpretations, summaries, site plans, and reports are independent works built on top of these inputs. They are not copies of or substitutes for the official data, by-law text, or professional output of any listed party. For the limits of our use of third-party data and services, see our Terms of Use and Disclaimer. Privacy is covered in our Privacy Policy.
This list is best-effort and may omit transitive dependencies. If you notice a missing or incorrect attribution, please let us know at hello@zoned.ca.
