Ontario Highway 69

King's Highway 69, commonly referred to as Highway 69, is a provincially maintained north–south highway in the central portion of the Canadian province of Ontario. In conjunction with Highway 400, it links Toronto with the city of Greater Sudbury at Highway 17, via Parry Sound. It is part of the Trans-Canada Highway and the National Highway System. From its southern terminus of Highway 559 at Carling, Highway 69 begins as Highway 400 narrows from a four-lane freeway to a two-lane highway. It travels northerly for approximately 68 kilometres (42 mi) to south of the French River, before widening back to a divided, four-lane freeway for approximately 64 kilometres (40 mi) into Sudbury. The final 6 kilometres (3.7 mi) of the route, connecting to Highway 17, is a five-lane arterial road that will be converted to freeway as the final phase of the four-laning.

Highway 69 was first designated in 1936 when the Department of Highways (DHO) assumed the Rama Road between Atherley and Washago. This short route was extended the following year when the DHO merged with the Department of Northern Development and expanded the King's Highway network north of the Severn River. By the beginning of World War II, the route reached as far north as Britt; a separate segment connected the town of Burwash with Sudbury. However, the rationing of labour and materials due to the war effort resulted in these two sections remaining separated until the mid-1950s.
