Research & Development

CHS is responsible for the surveying, measuring, describing, and charting of the physical features of Canada's oceans, seas, rivers, and lakes. The data are then used to produce nautical material including nautical charts (in both paper and digital formats), Sailing Directions, bathymetric maps, and Tides and Current Tables.

To support development of oil, gas, and other offshore resources, CHS works with the Geological Survey of Canada of Natural Resources Canada on special surveys.
