Highway 63 begins at Highway 11 and Highway 17 in North Bay and travels northeast to the Ontario–Quebec provincial boundary, where Route 101 continues into Témiscaming. It travels through the communities of Feronia, Redbridge, Balsam Creek, Eldee and Thorne. Prior to 1998, the route included a section of Cassells Street extending into downtown North Bay. Highway 63 is long, situated entirely within Nipissing District. Beginning in North Bay near Lake Nipissing, the source of the French River which flows down to Georgian Bay, Highway 63 travels east through suburbs. It exits the city and travels along the northern shores of Trout Lake, which serves as the headwaters of the Mattawa River, which flows into the Ottawa River and eventually the St. Lawrence River. The portion of Highway 63 west of Trout Lake travels between these water systems. The highway curves northeast to pass through the communities of Feronia and later Redbridge and Balsam Creek, after which it enters thick wilderness dominated by the Canadian Shield and Boreal Forest, with few residences or services outside of communities. It meanders northward, meeting the northern end of Highway 533, which travels south to Mattawa, approximately two-thirds of the distance between North Bay and the Quebec border. For the remainder of the highway, the route passes through isolated forests, travelling north, then curving east towards the Ottawa River. It passes through the community of Eldee before turning north alongside the river, following it up through Thorne. North of Thorne, the highway turns east and crosses the river into Quebec, becoming Route 101 and entering Témiscaming.
History
On August 25, 1937, the North Bay – Témiscaming Road was assumed by the DHO as Highway 63, connecting Highway 11 in downtown North Bay with the Ontario–Quebec border at Témiscaming. The road existed prior to this point as a northern development road. However, on April 1, 1937, the DND merged into the DHO. As a result, numerous highways were assumed in the northern regions of Ontario in mid-1937. The highway remained unchanged for over 60 years, until January 1, 1998, when the Connecting Link agreement through North Bay from Main Street to Highway 11 / Highway 17 - the North Bay Bypass - was rescinded. As a result, Highway 63 was shortened by.
