 A second more elaborate structure was built in 1862 by the HBC but its economic life was short-lived as the Company relinquished control of Rupert's Land with the 1870 Deed of Surrender.This deed transferred many HBC rights to the new Canadian national government.The fort had one more important role to play in history; it acted as a staging point for part of the North-West Mounted Police (NWMP) force that started at Fort Dufferin and headed west in 1874 to establish law and order in the future provinces of Alberta and Saskatchewan.
