Nine Mile Portage
Site of eastern terminus of an Indian portage from Kempenfeldt Bay to Willow Creek and thence by the Nottawasaga River to Georgian Bay. In the winter of 1813-14, a force under Lieut-Colonel Robert McDouall followed it on the way to relieve the isolated British garrison at Michilimackinac. That summer it was developed as a rough wagon road and till about 1830 was in frequent use for transport of supplies to Penetanguishene and the western military and fur trading posts.
