One Group.
Every Operational Need.
Supreme Management Group owns and operates specialized companies in security, surveillance, staffing, and commercial cleaning — serving organizations across Ontario and built to operate across Canada.
Licensed. Insured. Canadian-owned.
A management organization that owns the work
Supreme Management Group is the parent of four operating companies serving businesses, institutions, and property portfolios across Ontario. We are not a vendor, and we are not a broker — we own the companies that do the work.
Supreme Security Services provides licensed guards. Supreme Surveillance runs remote video monitoring. Supreme Employment supplies staffing. Profound Cleaning delivers commercial janitorial in 30+ cities.
Each company is a licensed specialist, and every one answers to the same leadership team and the same quality standard. For the organizations we serve, that means one place responsibility can land — no subcontractor maze, no vendors pointing at each other.
Four specialized companies. One standard.
Every Supreme Management Group company is independently focused and centrally accountable. Explore them individually, or combine them under one agreement.
Security Services
Licensed security guards
Uniformed guards, mobile patrol, and concierge security for condos, commercial buildings, and construction sites — every guard PSISA licensed.
Company Profile →Monitoring & Surveillance
Cameras that are actually watched
Live remote video monitoring, voice-down intervention, and lone worker response — connected to a real response capability the group owns.
Company Profile →Staffing & Workforce
The people your operation runs on
General labour, warehouse, industrial, and administrative staffing across Ontario — temporary, temp-to-hire, and direct placement.
Company Profile →Facility Services
Commercial cleaning you never chase
Janitorial programs, floor care, and post-construction cleaning across 30+ Ontario cities — one standard, one report format, one contact.
Company Profile →Built around the operations we serve
Most of our clients run buildings, sites, fleets, or facilities where a service failure costs real money by morning — and most use more than one of our companies.
One relationship. Full accountability.
The case for the group comes down to four facts you can verify before signing anything.
We own the companies that do the work
No subcontractor layer between you and the people on your site. When you escalate to the group, you are talking to the owner of the company responsible — not a broker reading from someone else’s contract.
Consolidated vendors, simpler operations
Replacing four vendor relationships with one group agreement collapses procurement, insurance verification, and coordination overhead into a single account contact, a single escalation path, and a single quality standard.
Licensed, insured, procurement ready
Our companies hold the licensing their industries require — including PSISA security licensing — with WSIB coverage and commercial general liability across the group. Certificates are ready the day your procurement team asks.
Canadian-owned, built to scale
Headquartered in Ontario and Canadian-owned. The group structure lets each company grow inside shared leadership, shared standards, and shared back-office strength. When your portfolio adds a city, the group follows.
What one group can do that five vendors can’t
Coordination is not something we promise to build after you sign. It is how the group was built.
Tell the group what you need
One conversation covering security, cleaning, staffing, monitoring, and healthcare support — in any combination.
We assemble the plan
Each company scopes its portion. The group aligns schedules, service levels, and reporting, and assigns one accountable point of contact.
You manage one relationship
Consolidated reporting. One escalation path that ends with an owner. One renewal date.
Built deliberately, growing across Canada
Each company exists because clients of the previous one kept asking for it.

Operator-led, hands-on by design
Supreme Management Group is led by operators, not absentee owners. The leadership team that sets the standard in the boardroom is the same one that inspects it on client sites — guard posts, cleaning routes, dispatch boards, and warehouse floors included.
That proximity is a policy, not a personality trait. It is how a group keeps four companies honest to one standard.
“We built this group around one belief: essential services fail when nobody is accountable. So we own the companies, we set the standard, and we answer for the result.”
— Mazhar Tahir, Founder & President
Anchored in Ontario. Structured for Canada.
The group’s companies serve clients across Ontario today, with active coverage in the Greater Toronto Area, Hamilton, Kitchener-Waterloo, London, Windsor, and more than 30 surrounding cities.
We are deliberate about geography. We enter a market when we can deliver the group’s standard there — licensed, staffed, supervised — and not before.
