Ontario Geological Survey Publications Release Notices
The Ontario Geological Survey regularly publishes maps, reports and digital data on Ontario's geology. The Publications Release Notice identifies upcoming publications one week prior to their release. Publications can be downloaded for free from the GeologyOntario application (links to new releases are provided in each Release Notice). Maps and reports in hard-copy (paper) format and digital data sets available on physical media (CD or DVD) can be purchased from the Publication Sales office.
To automatically receive the Publications Release Notice by email, subscribe to the distribution list by contacting Publication Sales.
Occasionally errors (errata) are found within publications. A list of publications with errata is available on the Errata webpage.
