In 1869, the Hudson's Bay Company agreed to surrender its monopoly in the North-West, including Upper Fort Garry. In late 1869 and early 1870, the fort was seized by Louis Riel and his Métis followers during the Red River Rebellion. After the Rebellion, the area around the fort continued to grow. In 1873, the city of Winnipeg was established and the name Fort Garry was no longer used. In 1881-1884 the majority of the fort was demolished to straighten Main Street (it was at Main Street and Assiniboine Avenue).
