Canadian Hydrographic Serv

    97 Products

    Since 1883, the Canadian Hydrographic Service has studied Canadian waters to ensure their safe, sustainable, and navigable use.

    Canada has the longest coastline of any country in the world, with more than a third of it's territory under water. 

    The CHS is a division of the science branch of Fisheries and Oceans Canada (DFO). With access to Canadian Coast Guard ships, the CHS takes advantage of every opportunity to take hydrographic and oceanographic measurements. They conduct regular field surveys, especially for higher risk, higher priority areas and produce navigation charts in both paper and electronic formats for most larger navigable waters in Canada
