Planning a road trip across Ontario? The journey from Sault Ste. Marie to Milton spans approximately 754 kilometers (468 miles) when traveling via Hurontario Street and Highway 10. This route connects two distinctly different regions of the province.
Sault Ste. Marie sits in the far northern reaches of Ontario, nestled along the St. Marys River where it forms the international border with Michigan's Upper Peninsula. The city serves as a gateway to the rugged wilderness of Northern Ontario and the Great Lakes.
Milton, by contrast, lies in the heart of the Greater Toronto Area (GTA) in Southern Ontario. This rapidly growing community sits along the Niagara Escarpment, offering residents proximity to Toronto's urban amenities while maintaining access to conservation areas and the Bruce Trail.
The primary route follows Hurontario Street northward, transitioning to Highway 10. This corridor cuts through the province's varied landscapes—from the Canadian Shield's rocky terrain in the north, through cottage country's lakes and forests, past the agricultural lands of central Ontario, and finally into the developed Golden Horseshoe region.
Drivers should plan for approximately 8-9 hours of driving time under normal conditions, though weather, traffic, and rest stops can extend this considerably. Winter travel requires particular caution, as Northern Ontario sections can experience severe snowstorms and reduced visibility.
The route passes near several notable destinations: Sudbury's mining heritage sites, the Muskoka Lakes region, Barrie's waterfront on Kempenfelt Bay, and the rolling hills of the Caledon area before reaching Milton.
