Local and live

Where the QEW meets the Welland Canal

St. Catharines straddles the QEW, where Niagara's 400-series highways connect, putting all of the Buffalo-Niagara border crossings 15 to 30 minutes away. The Welland Canal runs along the city's eastern edge, and a $5.2 million project at Port Weller is improving cargo-handling areas and developing 11 acres of land to support a cement trans-loading facility run with Stubbe's Cement, with Heddle Marine managing the dry docks and quay-side operations. General Motors' Propulsion Plant on Glendale Avenue, a 2-million-square-foot engine and transmission factory, draws in parts by truck from foundries in Ohio and Michigan, and the redeveloped Merritton industrial area now counts 452 businesses employing 4,787 people.

Trailers parked in the open are a target here. Niagara Regional Police said a utility dump trailer worth $15,000 was stolen from a property on Oakdale Avenue near Hickory Street in St. Catharines; the owner's hidden Apple AirTag tracker led officers to a property in West Lincoln, where two men, one from West Lincoln and one from Grimsby, were charged in connection with the theft. The same service has also been investigating a string of commercial break-ins across the region, with suspects smashing glass doors to get into businesses. For a yard near the canal or the QEW, an empty trailer or a loading dock left unwatched overnight is an open invitation.

Sigma covers St. Catharines warehouses, trucking yards and plant lots the same way, around the clock. Agents watch every camera live, 24 hours a day, 365 days a year, and AI person and vehicle detection flags anyone near parked trailers or loading docks after hours. The agent verifies it on video and gives a live, instant talk-down, then calls police and your contacts if the person stays put. Yard Operations adds truck and trailer logs, damage inspections and visual seal checks on video.

FAQ

St. Catharines monitoring questions

Can you watch a trailer yard near the Welland Canal or Glendale Avenue?

Yes. An agent has eyes on the cameras at all hours, all year. AI person and vehicle detection flags anyone near parked trailers or loading docks after hours, an agent verifies it on video, gives a live, instant talk-down through the site's speakers and calls police and your contacts if the person stays.

Can agents check drivers delivering to our St. Catharines plant or warehouse?

Yes, with Gate Operations. Carriers are checked on arrival: the agent speaks through the gate speakers, matches them to your rules and opens up remotely. Times and images are kept for each entry and exit.

Sigma is based in Acton. How does setup work for a St. Catharines site?

All the monitoring runs remotely through the site's internet connection. Our technicians come out to install the cameras and speakers, and compatible cameras already on site can often be connected. The site looks after the power, internet and gate.
