Local Coverage
Security services that match how Markham does business
Markham calls itself Canada’s high-tech capital, and the city counts more than a thousand technology and life-science companies among its employers, concentrated in the business parks along Highways 404 and 407 and the Commerce Valley corridor in Thornhill. Those campuses share a specific set of needs: reception coverage, employee and visitor access control, contractor sign-in, server-room and loading-area oversight, and after-hours checks that get documented.
The rest of the city runs on a different rhythm. Downtown Markham and Unionville South keep adding condo towers that need front-desk concierge coverage. Milliken and the Pacific Mall area carry some of the heaviest retail traffic in York Region. Cornell and Greensborough have active construction. And as anywhere in the GTA, property and vehicle theft stay a standing concern, which is why most properties end up layering cameras, lighting and patrol rather than leaning on an alarm alone.
Supreme Security Services is a licensed Ontario security agency, in business for more than 15 years, with its head office in Concord. We staff Markham sites with PSISA-licensed guards, run mobile patrol routes across the city, and monitor camera systems, so one accountable provider can cover the building, the lot and the cameras.
What We Provide
Security services we provide across Markham
Each service maps to a different kind of Markham property, from a corporate campus on the 404 to a condo tower in Downtown Markham.
Corporate and Office Security
Reception-desk guards, employee and visitor access control, contractor sign-in and after-hours lockup checks for tech campuses, professional offices and multi-tenant buildings.
See uniformed security servicesSecurity Camera Installation and CCTV
Camera installation is available through our security camera installation service, for offices, warehouses, plazas and condos, with layouts planned around real coverage gaps rather than a parts list.
See security camera installationLive Video Monitoring
Trained operators watch your cameras with alarm verification and documented escalation. Pairs with new or existing CCTV so the system does something at 3 a.m. besides record.

What changes from one part of Markham to another
The post orders for a Commerce Valley office campus and a Pacific Mall area plaza have little in common. Here is how the work differs across the city.
Downtown Markham and Unionville South
The new condo and mixed-use core. Buildings here need concierge coverage, visitor screening, parcel-room support, garage patrols and clean documentation for boards and property managers.
Commerce Valley and Thornhill
Corporate campuses and professional offices along the 404 and 407. Coverage runs on access control, reception presence, contractor management and after-hours floor checks.
Milliken and the Pacific Mall area
One of North America’s largest Asian retail clusters plus busy plazas. Typical scope: retail patrols, parking control, loss-prevention support and weekend coverage that scales with traffic.
The 404 business parks and Woodbine corridor
Warehouses, light industrial and tech facilities. Gate control, yard and perimeter patrols, camera monitoring and vacant-unit checks carry the load here.
Markville and central Markham
Established residential neighbourhoods, the Markville mall area and community facilities. Evening patrols, alarm response and school or community-event coverage are the usual asks.
Cornell, Berczy and Greensborough
Growing residential communities with active construction. Site hoarding checks, material and equipment protection, and patrols for newly registered condo and townhouse communities.
How It Works
How coverage starts at your Markham property
Call or request a quote
Tell us the property type, the problem and the hours you need. You get a written quote within 24 hours.
Site assessment
A supervisor walks the property with you, identifies weak points and writes the post orders your guards will follow.
Guards deployed
Most Markham sites are staffed within the same week, subject to scheduling. Urgent coverage is handled 24/7 and prioritized by our dispatch.
A recent engagement
A family leaving for an extended trip wanted more than an alarm. We scheduled house checks with photo-logged visits, mail collection checks and video monitoring alerts. They came home to a documented record of visits and zero surprises, and now book the same coverage for winter trips.
Areas We Cover
Where we work in Markham
Coverage spans Markham’s postal areas L3P through L6G, from the 404 corporate corridor and Downtown Markham to Unionville, Milliken, Cornell and Box Grove. That takes in the Commerce Valley and Thornhill office campuses, the condo core, the Pacific Mall retail cluster, the Woodbine business parks and the active construction on the eastern edges.
Guards are recruited local to Markham, with 24/7 dispatch behind them. Our head office is in Concord.
We also cover Richmond Hill, Scarborough and Stouffville. See every city we cover on our service area page.
Why Supreme
Why Markham businesses choose Supreme as their security agency
Supreme Security Services has been in business for more than 15 years, licensed and insured as an Ontario security agency, with its head office in Concord. Markham coverage runs with guards recruited local to the area, briefed on the specific property they protect, and backed by 24/7 dispatch. We say where we are based plainly, because trust starts with accuracy: what you get in Markham is local staffing with the systems, supervision and reporting of a GTA-scale agency.
Licensed and site-briefed guards
Every guard holds a valid Ontario security licence under the Private Security and Investigative Services Act, then is briefed on your property before the first shift: entrances, cameras, escalation contacts and reporting format.
Guards, cameras and monitoring from one provider
Most firms sell one piece. We staff the desk, monitor the cameras and route installation through our camera installation service, so you are not refereeing three vendors when something goes wrong.
Reports managers can act on
Shift logs, incident reports, visitor records and patrol checks written in plain English and delivered on schedule, written so a manager, board or insurer can use them afterward.
Coverage sized to the site
A 10-person office does not need what a corporate campus needs. We quote guards, patrol, cameras, monitoring or a mix after seeing the site, and we say so when the cheaper option is enough.
Verified Reviews
What clients say about working with Supreme
