Ontario Highway 803 History - The King's Highways of Ontario

Tertiary Highway 803 was a short local road serving as an access point to Night Hawk Lake from Highway 101 near Timmins. The highway came into existence in 1970, when Secondary Highway 575 was re-designated as Tertiary Highway 803. The route number change took effect on July 2, 1970. Highway 803 holds the record for Ontario's shortest Tertiary Highway, with a total length of just under 5 km. The highway remains a gravel-surfaced road to this day. On March 31, 1997, the Ministry of Transportation transferred jurisdiction over Highway 803 to the City of Timmins. The former highway is now known as Night Hawk Lake Road.
