The Canadian Hydrographic Service

The Canadian Hydrographic Service (CHS) provides detailed mapping and charts of Canada's oceans, lakes, and rivers. These charts help ensure safe navigation for ships, support marine activities, and assist in environmental and resource management. Using advanced surveying technology, CHS collects data on water depths, coastlines, and underwater hazards to produce accurate, up-to-date nautical charts. Their work is essential for maritime safety, commerce, scientific research, and public safety, serving government agencies, mariners, industry, and the public across Canada's vast inland and offshore waters.
