The mountain had been named Mount Baynes c1859 by Captain Richards, RN, and so-labelled on British Admiralty Chart 2840, 1861, however local residents began calling this Mount Maxwell at about the same time. "Mount Maxwell (not Mount Baynes)" was adopted 2 May 1911, as an entrenched local name. By correspondence with local authorities on Saltspring Island, it was agreed in 1939 to designate the highest point Baynes Peak, and name the newly-created surrounding park Mount Maxwell Park (file M.1.36).

" [Saltspring 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."
