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.

Route description
Highway 634 is an isolated bush highway that connects Highway 11 in the community of Smooth Rock Falls with the Abitibi Canyon hydroelectric dam. The road is 80.3 km (49.9 mi) in length. Like most other two-lane roads in Ontario, the speed limit is 80 km/h (50 mph) although there are sections where such cannot be maintained. The first 65 km (40 mi) of the route is paved, while the last 15 km (9.3 mi) is gravel. The route passes through the communities of Brownrigg along its otherwise isolated route through the Canadian Shield within thick Boreal Forest. At Fraserdale, drivers must turns northeast to reach the Abitibi Canyon Generating Station. Highway 634 ends at the western edge of the dam; the locally maintained Otter Rapids Road continues west of there. A forest road also travels west from Fraserdale to the community of Smokey Falls.
Like other provincial routes in Ontario, Highway 634 is maintained by the Ministry of Transportation of Ontario. In 2010, traffic surveys conducted by the ministry along a lone section of the route showed that on average, 120 vehicles used the highway daily between the northern outskirts of Smooth Rock Falls and Fraserdale.
History
The Highway 634 designation has existed along two routes. The original designation connected Highway 144—then designated Highway 544—in Chelmsford with Highway 69 in Val Caron, entirely within what is now Greater Sudbury. This routing was first designated c. 1962 and remained in place until c. 1974, at which point it was transferred to the Regional Municipality of Sudbury and eventually designated as Municipal Road 15.
The current routing of Highway 634 is one of the northernmost in Ontario. It was originally opened as Highway 807 on July 21, 1966. However, Highway 807 was redesignated as Highway 634 in 1977, establishing the current route. Within Smooth Rock Falls, a slight realignment was constructed during the 1980s, but otherwise the route has remained unchanged.
