Had been labelled "Chuan Island" on "Plan to accompany the Report of a Canoe Expedition along the East Coast of Vancouver Island" by Governor James Douglas, 1854; spelled "Chouan" elsewhere. The name "Saltspring" was given early by Hudson's Bay Company officers who were interested in obtaining salt from the fourteen briny springs on this island. Labelled "Saltspring Island" on Joseph Pemberton's "Map of Southeastern Vancouver Island", produced for the Hudson's Bay Company in 1855, and on a map to accompany Capt. W. Colquhoun Grant's "Description of Vancouver Island", 1856.

"Saltspring Island... given by the officers of the Hudson's Bay Company, because a number of springs of brine (3,446 grains of salt to the imperial gallon) exist on the island, was changed by Captain Richards on surveying the surrounding waters in 1859, to 'Admiral island'. The first settlers arrived on the island in 1859. Locally, notwithstanding the surveyor's change, the island has always been known as Saltspring, and consequently this name was re-adopted by the Geographic Board of Canada in 1905..." [note that "Saltspring Island" was not actually adopted by the Geographic Board of Canada until 1 March 1910, according to a June 1910 letter from GBC, file V.1.10 ]

"Regarding the name of Admiral island, Captain Richards when surveying here evidently wished to associate the island with Rear Admiral Baynes, commanding at the time, 1857-1860, the Pacific station, his flagship, staff and officers etc. He therefore named the highest mountain Baynes, and the island Admiral; Ganges harbour after the flagship; Fulford harbour after the captain; Burgoyne bay after the commander; Southey point after the admiral's secretary; Mount Bruce after the previous commander in chief; and Cape Keppel after a friend of Admiral Baynes."
