Report chart discrepancies

We want to hear from you. We rely on mariners to notify us when dangers to navigation are discovered, or when 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.

Fill out our  marine information reporting form (PDF version - 93.4 kb) and email it to:  chsinfo@dfo-mpo.gc.ca.
