The Nine Mile Portage is an aboriginal transportation route that existed centuries before Europeans came to Simcoe County. The portage linked Kempenfelt Bay through Willow Creek, connecting Lake Simcoe to the Nottawasaga River which flows into Georgian Bay off Lake Huron.Barrie played an integral role in the War of 1812. During the War, the city became a supply depot for British forces, and in addition, the Nine Mile Portage was adopted by the British Military as a key piece of their supply line which provided a strategic path for communication, personnel, and vital supplies and equipment to and from Fort Willow and Georgian Bay / Lake Huron. Today, the Nine Mile Portage is marked by signs along roads in Barrie and in Springwater Township. You can follow the scenic path from Memorial Square all the way to Fort Willow.
