Report Chart Discrepancies

We want to hear from you. CHS relies on mariners to notify us when dangers to navigation are discovered, or corrections to charts and publications seem necessary. It's important to provide us with as much information as possible so we can make the changes and ensure safe navigation for all.

Please fill out our Marine Information Reporting Form and email us at: chsinfo@dfo-mpo.gc.ca
