Open Data Directive

Ontario’s Open Data Directive maximizes access to government data. It requires the data we hold to be made public unless it is exempt from release. Exemptions may be for legal, privacy, security, confidentiality or commercially sensitive reasons.

We support the commitment to openness, accountability and transparency through the Open Data Directive.

Cancer Care Ontario is now part of Ontario Health. For Ontario Health’s data inventory, or to request a specific data set, see the Open Data section on the Ontario Health Corporate Documents page.
