In 1882, the loss of the steamship [[SS Asia|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 Ocean|Pacific]] coast in 1891, tidal and current metering nationwide began in 1893, surveying and charting extended to the [[Canadian Maritimes|Maritimes]] by 1905, and water level gauging of the [[Great Lakes (North America)|Great Lakes]] began in 1912.<ref name="AOLS" />

In 1904, a [[Queen's Privy Council for Canada|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|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 and Labrador|Newfoundland]] into Confederation, with CHS taking over surveys and charting around the island of Newfoundland and the coast of [[Labrador]] from the Royal Navy.<ref name="AOLS" />
