Purchase charts for navigation

CHS distributes nautical charts for navigation through a dealer network that serves Canada and the entire world. You can use this page to find the nautical charts that you need and choose the dealer from which you will order them.

Find nautical charts

Many Canadian Hydrographic Service (CHS) charts are available in digital form as either a Raster Navigational Chart (RNC) or as a vector Electronic Navigational Chart (ENC). Both charts use navigation software to provide navigators with an electronic alternative to paper charts. Learn more about the difference between raster charts and vector charts.

To find the chart that you need, you can search our chart catalogues or our interactive maps.
