Canadian Hydrographic Service
The Canadian Hydrographic Service (CHS) is part of the federal department of Fisheries and Oceans Canada and is Canada's authoritative hydrographic office. The CHS represents Canada in the International Hydrographic Organization (IHO).
The CHS is administratively part of Fisheries and Oceans Canada's Oceans and Ecosystems Science Sector. According to mandated obligations of the Oceans Act and the Canada Shipping Act, the CHS is led by the Hydrographer General of Canada who is responsible for gathering, managing, transforming and disseminating bathymetric, hydrographic and nautical data and information into paper and electronic nautical charts, as well as publications and "hydrospatial" (blue geospatial) data and services, including updating services of: broadcast Navigational Warnings and/or Notices to Mariners; and, other publications, data and services of: Tide & Current Tables; water levels observations in near-real time, real-time and forecasting; Sailing Directions and hydrospatial dynamic data, products and services primarily for safe and efficient navigation in Canadian waters and much more.
CHS is responsible for leading and coordinating the Government of Canada's implementation of a Marine Spatial (Hydrospatial) Data Infrastructure (HDI=MSDI) as a key oceans and freshwater component of the Canadian Geospatial Data Infrastructure (CGDI). MSDI (or HDI) compatible and interoperable globally within the directions and framework of the United Nations Global Geospatial Information Management (UN-GGIM). Feeding and guiding future needs and requirements, such as standard near real-time and real-time Hydrographic and Hydrospatial Dynamic Products, for safe and efficient navigation, and serve new technologies such as Maritime Autonomous Surface Ships (MASS); in close collaboration with Natural Resources Canada's (NRCan) Mapping and Earth Observation (CCMEO) Branch colleagues.
Prior to Confederation, responsibilities for hydrographic survey and chart production in British North America rested with the Royal Navy.
In 1882, the loss of the steamship SS Asia on an uncharted shoal in Georgian Bay resulted in 150 fatalities and was Canada's worst maritime disaster at the time. On August 13, 1883, the Dominion government established the Georgian Bay Survey which was empowered by legislation with the responsibility to survey and chart navigable waters of Georgian Bay and Lake Huron.
Surveying and charting was extended to Canada's Pacific coast in 1891, tidal and current metering nationwide began in 1893, surveying and charting extended to the Maritimes by 1905, and water level gauging of the Great Lakes began in 1912.
In 1904, a Privy Council order renamed the Georgian Bay Survey to the Hydrographic Survey of Canada with some modified responsibilities. In 1913 one of Canada's most famous hydrographic survey vessels, CSS Acadia was commissioned for use on the Atlantic coast. In 1928, the organization was renamed to the Canadian Hydrographic Service. Responsibility was extended on March 31, 1949, with the entry of Newfoundland into Confederation, with CHS taking over surveys and charting around the island of Newfoundland and the coast of Labrador from the Royal Navy.
CHS is a world leader in the adoption of hydrographic survey technology, as well as in research and development. With responsibility for charting the world's longest coastline (243,792 kilometres) as well as 6.55 million square kilometres of continental shelf and territorial waters (second largest in the world), including extensive inland waterways such as the St. Lawrence Seaway, CHS maintains a world-record inventory of more than 1,000 published charts. As such, the organization was an early adopter of single-beam sonar, radio-navigation positioning systems, and computer processing and storage.
