Protecting Saint John Around the Clock

Xtreme Security Inc. serves Saint John and southern New Brunswick 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.

Canada's oldest incorporated city is also one of its most industrial — the port, the refinery complex and energy terminals demand industrial-grade security. We provide gatehouse operations, contractor screening, perimeter patrols and after-hours monitoring for port-adjacent and industrial clients.

Uptown Saint John, the Boardwalk district, cruise ship season and the hospitality sector need visible, professional public-facing security. Our officers and event teams handle retail corridors, venues and seasonal tourism traffic with approachable, firm presence.

The regional hospital, university campus, retail centres and construction sector complete our coverage. From institutional access control to loss prevention and fire watch, every shift is documented with GPS-verified checklists and live photos.
