Warehouse and yard security in Cornwall
Sigma's live agents watch Cornwall warehouses, trucking yards and job sites near Highway 401 and the border around the clock, and act while an intrusion is still happening.
Local and live
The Cornwall Business Park, the 401 and the border
Cornwall sits on Highway 401 and the CN mainline between Toronto and Montreal, with VIA Rail serving the city's north-end station. The Three Nations Crossing bridge connects Cornwall to Roosevelltown, near Massena and Malone, New York, and the St. Lawrence Seaway Management Corporation is headquartered in the city. Cornwall's Business Park holds two large distribution centres: Walmart's original 1.5-million-square-foot facility, which employs nearly 1,000 people, and a second distribution centre on a 169-acre parcel that Walmart took over after Target Canada left the Canadian market in 2015.
Freight moving through that corridor can carry more than what's on the manifest. On February 5, 2025, a Ministry of Transportation safety inspection of a tractor-trailer near Cornwall found two stolen vehicles hidden inside a sea container on the trailer; they had been reported stolen out of Toronto weeks earlier, and OPP charged the driver with possession of property obtained by crime over $5,000. For a Cornwall yard or distribution site, the same highway and border access that bring in freight can also move stolen goods through quickly.
Cornwall properties get watched around that same border and highway traffic. Live agents cover every camera at once, and AI person and vehicle detection flags anyone on the lot after the business closes for the night. The agent on shift checks the live video, gives a live, instant talk-down through the site's speakers and calls police and your contacts if the person stays, and Gate Operations keeps a log of every truck that comes through the gate after hours.

The vehicles had been reported stolen out of Toronto weeks earlier, and OPP charged the 61-year-old Toronto driver with possession of property obtained by crime over $5,000.

FAQ
Cornwall monitoring questions
Our distribution centre is in the Cornwall Business Park. Can you watch the yard and loading docks?
Yes. Cameras and speakers are installed over the docks, the yard and the fence line, and AI detection flags anyone there once the building is closed for the night. An agent confirms it live, delivers a live, instant talk-down and calls police and your contacts if it's warranted.
Can agents check drivers crossing in from the Three Nations Crossing or arriving at our Cornwall yard at night?
Yes, with Gate Operations. The agent on duty sees each driver arrive, speaks with them through the gate speakers, checks them against your rules, schedule or pickup list, and opens the gate remotely when it matches. Each entry and exit is recorded with a time and an image.
We're near the border, not near Acton, Ontario. How does Sigma set up a Cornwall site?
The border doesn't change anything, since monitoring is done remotely over the internet rather than in person. A Sigma technician still comes out to install the cameras and speakers, and compatible cameras already on a Cornwall property can often be connected instead of replaced. Your side keeps the power, the internet connection and the gate running.
How do I get started?
Request a free site assessment or call (416) 477-5589 ext 2. A Sigma specialist reviews your layout, existing cameras and risks, then recommends the right coverage, at no cost and with no obligation. Every quote costs less than a 24/7 guard.
