 The Canadian Department of Marine and Fisheries took over control of the shore establishment and the responsibility of enforcing control of Canada's maritime interests in the area after the Royal Navy left.After passage of the "Naval Service Act" in 1910 there was a Canadian Naval Service (CNS) that controlled the base and the CNS became the Royal Canadian Navy in 1911.Although the original graving dock was large enough to accommodate the largest ships in the British Pacific fleet at the time of its construction, by the early 20th century larger ships were routinely being built.
