Where Highway 17 meets the International Bridge

Sault Ste. Marie is the single road crossing for commercial traffic on a stretch of the Canada-US border that runs from Sarnia to Pigeon River, about 1,300 kilometres, and the Sault Ste. Marie International Bridge carried 42,365 truck crossings from January through August 2025, connecting to I-75 in Michigan. Highway 17, the Trans-Canada, reaches the bridge after crossing the Montreal River Hill, and three railways serve the city: Canadian National, Canadian Pacific and the Huron Central Railway, which carries coil steel from Algoma Steel and paper from the Domtar mill in Espanola for about 80 percent of its freight. The city is negotiating a long-term lease with Algoma Steel for 216 acres of brownfield land for a heavy industrial park, with an option on 950 acres more.

A fenced compound isn't always enough. In August 2025, thieves breached the fence around a road contractor's trailer on Bay Street, supporting road work on nearby Queen Street East, and cut a hole in the trailer's floor from underneath to get in. They drove off with a Ford F-150 pickup truck and took tools, computers, two GPS rover units used to lay out the job and the keys to other vehicles, in a break-in valued at about $90,000. For a Sault contractor or industrial yard, the lesson is the same: a locked compound on its own doesn't stop someone who has the time to get through the floor.

Sigma watches a Sault Ste. Marie job site or yard live instead of waiting for the morning walk-through. AI person and vehicle detection flags anyone near the compound or fence after hours, an agent checks the camera, gives a live, instant talk-down through the site's speakers and calls police if the person doesn't leave. For cross-border fleets, Yard Operations adds truck and trailer damage inspections and visual seal checks on video, while Gate Operations checks each driver before the gate opens.
