Ontario Highway 634
Ontario provincial highway
Secondary Highway 634, commonly referred to as Highway 634, is a remote highway in Northern Ontario that connects Highway 11 in Smooth Rock Falls to the Abitibi Canyon Generating Station in the community of Abitibi Canyon, Ontario. It is the second highway in Ontario to be designated Highway 634, with the original Highway 634 being near Sudbury. The current routing was at first designated as Highway 807, but was renumbered in 1977. The road was re-aligned around the eastern part of Smooth Rock Falls in the mid-1990s.
As of 2019, the entire route is paved. Services along the route are only available within Smooth Rock Falls. Two additional communities exist along Highway 634: Brownrigg and Fraserdale.
