Oshawa security at a glance
Supreme Security Services is a licensed security company serving all of Oshawa, from downtown storefronts and the 401 industrial corridor to north Oshawa (postal areas L1G through L1L). Uniformed guard coverage starts around $28 per hour, quotes arrive within 24 hours, and dispatch answers 24/7.
Business-First Coverage
What the security companies in Oshawa should actually be doing for you
Most Oshawa businesses do not need a lobby full of guards. They need a storefront that stops getting hit overnight, a plaza where the parking lot behaves, a warehouse where trailers stay put over the long weekend, or a student rental building where move-in season does not turn into a damage claim. That is the work we build quotes around.
Oshawa’s mix makes the job varied. Downtown is reviving, with new residents, restaurants and offices, but it still carries more street-level pressure than anywhere else in Durham, and businesses there feel it in break-ins and trespassing. The 401 and Stevenson Road corridors run on manufacturing and logistics, anchored by the GM assembly plant and its supplier network. North Oshawa is one construction site after another as the city grows around Ontario Tech and Durham College, whose students fill rental buildings across the city.
Supreme Security Services has been in business for over 15 years, with 24/7 dispatch from our head office in Concord. Every guard is licensed under Ontario’s Private Security and Investigative Services Act, insured, and briefed on your site’s access points, house rules and reporting format before the first shift.

What We Provide
Security services we provide across Oshawa
Each service maps to a different kind of Oshawa property, from a downtown storefront to a yard off Stevenson Road.
Business and Commercial Security
Uniformed guards for storefronts, offices, plazas and commercial buildings. Opening and closing coverage, trespass response, loss-prevention support and documentation you can hand to your insurer.
See uniformed securityMobile Patrol
Logged vehicle patrols for plazas, lots and multi-site portfolios. Scheduled or randomized rounds, lockups, unlocks and alarm response, billed per visit so smaller businesses can afford real coverage.
See mobile patrolWarehouse and Industrial Security
Gate control, driver sign-in, yard patrols and overnight coverage for the 401 corridor, the Stevenson industrial parks and the auto-supplier network.

What changes from one part of Oshawa to another
A downtown storefront and a Kedron construction site fail in completely different ways. Here is how coverage differs across the city.
Downtown Oshawa
Storefronts, offices and new residential above retail, with the heaviest street-level pressure in Durham. Businesses here want evening presence, trespass response handled calmly, and documentation for police follow-up.
Oshawa Centre and Vanier
Durham’s biggest mall and the plazas around it. Retail patrols, parking control, loss-prevention support and closing-time coverage lead the requests.
South Oshawa and the port lands
Industrial operations, the Port of Oshawa and older employment lands. Gate control, perimeter patrols and camera monitoring with logs kept tight for insurers.
Stevenson Road and the 401 corridor
Manufacturing and logistics anchored by the GM assembly plant and its suppliers. Yard checks, trailer security, driver sign-in and overnight patrols carry the load.
North Oshawa, Windfields and Kedron
The growth front: subdivisions under construction and new plazas around Ontario Tech and Durham College. Site security, material protection and patrols for newly built communities.
Taunton and Harmony corridors
Big-box retail, supermarkets and established residential. Evening plaza patrols, alarm response and parking control are the usual scope.
Pricing
What security coverage costs in Oshawa
Most Oshawa clients pay between $28 and $45 per hour for uniformed guard coverage, in line with 2026 rates across the GTA. The exact rate depends on hours per week, the number of guards, the training the post requires, and how quickly coverage must start. Longer contracts bring the hourly rate down, and same-day requests carry a premium.
As a guide to 2026 ranges: a uniformed security guard on a single site runs $28 to $35 per hour, a condo concierge or front desk officer $28 to $34 per hour, and a construction site or fire watch guard $30 to $40 per hour. Mobile patrol starts from $25 per visit, and event security staff run $35 to $45 per hour.

How It Works
How coverage starts at your Oshawa 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 Oshawa 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 distribution warehouse asked for overnight coverage after thefts at neighbouring properties. We combined an on-site guard with live video monitoring of the yard. When intruders tested the fence line one night, the operator saw it live, the guard responded, police were called, and nothing left the property.
Areas We Cover
Where we work in Oshawa

Why Supreme
Why Oshawa businesses keep us after the first contract
Supreme Security Services is a licensed and insured Ontario security agency, in business for more than 15 years, operating from our head office in Concord with dispatch answering 24/7. Most of our Oshawa work is small and mid-size business coverage, which means the pricing model and the reporting are built for owners, not just for downtown towers.
Sized for small business, not just towers
Per-visit patrol pricing and shared routes mean a single storefront can afford professional coverage. You are not subsidizing a service model built for downtown Toronto towers.
Licensed and briefed before shift one
Every guard holds a valid Ontario security licence under the PSISA and walks the site with a supervisor first: entrances, cameras, escalation contacts and reporting format.
Reports you can actually use
Shift logs, incident reports and patrol records in plain English, delivered on schedule and written so a manager, board or insurer can use them. When something happens, you have evidence instead of an argument.
A named supervisor who answers
One supervisor owns your site, knows its history and picks up the phone. No ticket queue between you and the person responsible.
