/ Markham · Overview
Licensed security guards in Markham.
Markham runs on technology and logistics. We protect corporate campuses along Highway 7 and the 404 corridor — access control, visitor management and executive floor coverage for technology head offices — and we patrol the warehouse and light-industrial belts around Woodbine, Steeles and the 407. Data-centre clients receive NDA-signed officers and documented escort procedures as standard.
Markham sits inside our York Region dispatch zone: average alarm response is 12 minutes, with GPS-verified checkpoint scans on every patrol and a report in your inbox before your next business day. Coverage extends across Unionville, Markham Village, Cornell, Milliken, Cathedraltown and Thornhill — from Main Street retail and Pacific Mall-area plazas to residential estates and active subdivision construction.
Tell us the property type, the hours you need covered and what concerns you most — tailgating at a lobby, after-hours dock doors, a construction perimeter. We will come back with a written post order and a firm start date, typically within 24 to 72 hours.
