In 1841 James Douglas was charged with the duty of setting up a trading post on the southern tip of Vancouver Island, upon the recommendation by George Simpson a new more northerly post be built in case Fort Vancouver fell into American hands (see Oregon boundary dispute). Douglas founded Fort Victoria on the site of present-day Victoria in anticipation of the outcome of the Oregon Treaty in 1846, extending the British North America/United States border along the 49th parallel from the Rockies to the Strait of Georgia.
