Ontario Highway 93

Ontario Highway 93

King's Highway 93, commonly referred to as Highway 93, is a provincially maintained highway in the Canadian province of Ontario. Located entirely within Simcoe County, the highway extends for 23.9 kilometres (14.9 mi) from an interchange with Highway 400 in Springwater, just south of the community of Hillsdale, to an intersection with Highway 12 at the town limits of Midland.

The route follows the Penetanguishene Road, an early colonization road which served to connect Lake Simcoe with Georgian Bay, thus providing an overland route from Lake Huron to Lake Ontario via Yonge Street.

Prior to 1997, the highway was fully twice as long, extending 15 kilometres further south to meet Highway 11 and Highway 400A at Crown Hill, and seven kilometres further north to Penetanguishene. Because the southern leg was only two kilometres east of Highway 400, and the northern segment carried primarily municipal traffic in Penetanguishene and Midland, both segments were transferred to Simcoe County that year. Both segments continue to be known as Simcoe County Road 93.
