Canadian Hydrographic Service

The Canadian Hydrographic Service (CHS) is a government agency responsible for mapping and studying Canada's waterways, including oceans, rivers, and lakes. Its main goal is to provide accurate nautical charts and data to ensure safe navigation for ships and recreational boaters. CHS collects information on water depth, tides, currents, and underwater features, which is essential for marine safety, environmental protection, and resource management. By delivering reliable and up-to-date information, CHS supports Canada’s maritime activities and contributes to safe travel and commerce across its vast aquatic landscapes.
