Update Your Chart

Many mariners understand the importance of having charts onboard but it’s just as important to ensure your charts are up to date.  If a buoy has changed or there is a new obstruction, you need to know about it before you encounter it, not after.  CHS regularly updates charts and it’s essential you have the latest updates for safe navigation.

There are different ways to find out about chart updates depending on the type of chart you have.

Paper Charts

If you have a paper chart, you can register on the Notices to Mariners web site to receive email notifications of updates to your chart.  Chart corrections are issued through Notices to Mariners by the Canadian Coast Guard.  These notices contain updates to charts as well as sailing directions, buoys, radio aids and more.  You can also print patches to your charts from this web site.

Digital Charts

If you have registered your digital chart with CHS, you will automatically receive updates and new editions for one year from the date of registration.

  • Electronic Navigational Charts:
    You will receive updates on an ongoing basis through an online account CHS will set up for you after you register your chart.
  • Raster Navigational Charts:
    If you have registered a raster (BSB) CD, you will now have access to our new online service for monthly updates.  Or, you can request an updated CD which will be available each May.
