Protecting St. Catharines Around the Clock

Xtreme Security Inc. serves St. Catharines and the Niagara Region from our national network of 4,800 full-time security professionals, with access to 17,000 hired guards across Canada. As a privately-owned Canadian company operating in every province, every local assignment is backed by our 24/7 National Security Operations Centre, 270+ marked mobile patrol units and 40+ regional offices.

The Garden City's manufacturing base — automotive parts, industrial plants and the Welland Canal corridor — needs gatehouse operations and industrial yard security. We provide contractor screening, shift-change access control and overnight compound patrols for industrial clients across Niagara.

Niagara's wine country, hospitality venues and tourism traffic create constant demand for event and venue security. From winery events to festivals and the performing arts centre, our teams handle ticket checks, crowd management and access control.

Brock University, the hospital, downtown retail and the Pen Centre corridor complete our coverage. From institutional access control to loss prevention and construction site security, every shift is documented with GPS-verified checklists and live photos.
