Digital Charts

The CHS distributes its nautical charts and publications to over 700 dealers across Canada and around the world. You can use this site to find the chart that you need and the dealer nearest you. By using the new CHS Chart Registry Service and Digital Data Portal to register your digital charts, you will ensure that you have the latest and most up to date charts.

Many CHS charts are available in digital form as either a Raster Navigational Chart (RNC) in the BSB format or as an Electronic Navigational Chart (ENC) in the S-57 vector format. Both kinds of electronic charts, when used with navigation software, contribute to safer navigation. Digital charts are available individually and in geographic collections on CD and on-line.

ENCs offer powerful on-screen navigation via an Electronic Chart Display and Information System (ECDIS) and meet the official S-57 international standard.

Raster navigational charts (RNC) are simply an electronic image of the paper charts and are most commonly used on pleasure craft as well as smaller commercial vessels.  The Canada Shipping Act requires mariners using RNCs to also carry paper charts as a backup.

Update Your Chart

Find Digital Chart Updates

Many mariners understand the importance of having charts onboard but it’s just as important to ensure that 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 is essential that you have the latest updates for safe navigation.

If you have registered your digital charts with CHS, you will automatically receive updates and new editions through the CHS Chart Registry Service and Digital Data Portal.

  • Electronic Navigational Charts (ENC)
    You will receive updates for the duration of your licence.
  • Raster Navigational Charts (RNC)
    If you have registered raster BSBv4 products you will automatically receive updates and new editions for two years from the date of registration.  If you have registered BSBv3 products you will receive updates for the duration of your licence.

KEEP YOUR CHARTS UP TO DATE.   Every month we update Canadian Hydrographic Service Digital Charts® to ensure you are navigating with the latest available information.  Updates may consist of a New Chart, a New Edition or a change to the existing edition of a chart as advertised in Notices to Mariners.  Monthly updates are included with your licence.

CHS’ BSBv4 charts are not GIS compatible.

If you wish to use CHS BSB charts in GIS software please contact CHS by e-mail at for the appropriate licence agreement and we will then provide you with files appropriate for use with GIS.
