About Security ONE.
Protecting Southern Ontario since 1974. We're a local, family-minded team driven by a single mission — to give our community genuine peace of mind through technology and service no national chain can match.
Trusted by leading organizations
To provide cutting-edge security solutions that bring peace of mind to homes, businesses, and communities across Ontario.
Every system we design, every line we monitor, and every technician we send begins with that single promise — protection you can feel, delivered by people who live here too.
Five decades of trust.
Founded in Ontario
Security ONE opens its doors with a simple promise — protect our neighbours with technology and service no national chain could match.
Monitoring Centre
We built our own ULC-certified monitoring centre, staffed entirely by local operators — never outsourced, never automated.
Smart Integration
We pioneered fully integrated smart-home and commercial platforms across Southern Ontario, unifying surveillance, access, and automation.
50+ Years Strong
Five decades on, we still never subcontract a single install — every technician is a vetted, certified member of our own team.
What sets us apart.
After fifty years, our advantage isn't a product — it's a standard we refuse to compromise.
Never Subcontracted
Every technician and operator is a direct, vetted employee — accountable to you and to us, never a third party.
Proprietary Technology
We install and support a rigorously tested, end-to-end encrypted hardware ecosystem for uncompromising reliability.
Genuinely Local
Live Ontario operators and regional response teams who know the community they protect — because they live in it too.
Licensed, certified, and built to protect.
Our ULC- and CANASA-certified monitoring means your alarms are answered by accredited operators held to the highest national standards — right here in Ontario, around the clock.
Rooted in the communities we protect.
Protecting Ontario means more than installing systems. We invest in the people and places that make this region home.
- Sponsoring local youth and community safety programs across the region
- Supporting first responders and emergency services initiatives
