Ontario Highway 525 (#2) History - The King's Highways of Ontario

Another Secondary Highway 525 was established in the early 1980s in the District of Kenora. This highway was created out of a route renumbering, when an existing section of Highway 596 northwest of Minaki was renumbered as Highway 525. The new Highway 525 route number came into effect on April 1, 1981. The highway is gravel-surfaced for its entire length. Unless posted otherwise, the speed limit on Highway 525 is 80 km/h (50 mph). A different, unrelated Highway 525 existed in the Gravenhurst area between 1956 and 1972.
