Canadian Hydrographic Service Digital Charts

Although CHS does not sell charts directly to the public, we distribute to over 800 dealers across Canada and around the world. You can use this site to find the chart you need and the dealer nearest you. You can also register your digital chart to ensure you receive the latest updates.

CHS offers exceptional digital charts in two formats – Electronic Navigational Charts (ENCs) and raster (BSB) charts. Both charts are available on CD and run on onboard computers.

ENC charts offer powerful onscreen navigation via an Electronic Chart Display and Information System (ECDIS) and meet the official S-57 international standard.

Raster charts are simple electronic versions of paper charts, popular on pleasure craft. Mariners using raster charts are required under the Canada Shipping Act to also carry paper charts as a backup.

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.

Update Chart

Find Digital Chart Updates

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.

If you have registered your digital chart with CHS, you will automatically receive updates and new editions for two years 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 (BSB) Charts:
    If you have registered a 2009 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.

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.

BSB v4 raster charts are not GIS compatible.
