Ontario Highway 141 History - The King's Highways of Ontario

King's Highway 141 is a minor collector highway serving the northern Muskoka Lakes region, connecting Highway 11 near Utterson with Highway 400 south of Parry Sound. The highway was created in 1974 when Secondary Highway 532 was renumbered as King's Highway 141 between Utterson and Hayes Corners. The route of Highway 141 remained unchanged until 2003, when Highway 141 was extended westerly from Hayes Corners to meet up with a new section of Highway 400. The extension added approximately 4 km to the length of the highway.

Highway 141 is a two-lane highway for its entire length. The highway passes through mostly rural areas along its route. A 3.5 km section of Highway 141 is signed concurrently with Highway 69 between Hayes Corners and the Parry Sound Airport. Services are rather scarce along this highway outside of larger communities. The speed limit on Highway 141 is 80 km/h (50 mph), unless posted otherwise. Please visit the Highway 141 Mileage Chart page for a list of mileage reference points along Highway 141.
