Highway 118 follows or roughly traces the eastern portion of the Monck Road, between Tory Hill and Paudash.

[15] The newly formed District Municipality of Muskoka decided to extend the Peterson Road, which fell into disuse east of Vankoughnet in the 1870s, to Carnarvon, despite nearly half of the route lying in neighbouring Haliburton County.
