when did british columbia became a province of canada
British Columbia With the agreement by the Canadian government to extend the Canadian Pacific Railway to British Columbia and to assume the colony's debt, British Columbia became the sixth province to join Confederation on July 20, 1871. The borders of the province were not completely settled. The Treaty of Washington sent the Pig War San Juan Islands Border dispute to arbitration in 1871 and in 1903, the province's territory shrank again after the Alaska boundary dispute settled the vague boundary of the Alaska Panhandle.
