Security ONE


Security ONE has been the premier security company in Southwestern Ontario for over 30 years. Locally owned and operated since 1978, the company has been led by a group of individuals with an extensive background in commercial and residential security.

We are a member of the Better Business Bureau, Canadian Alarm & Security Association (CANASA) and listed with Underwriters Laboratories Canada (ULC).


We offer 24-hour, 365-day a year monitoring of your home, office, or medical alert of a loved one. All of our monitoring is done locally, based out of our Leamington, Ontario monitoring station.

Security ONE is an authorized dealer for Honeywell and First Alert Security System. We provide our customers with complete solutions, and a full line of security products and services. We offer additional monitoring services such as low temperature, rising sump pump levels, asset protection, and protection from noxious gases.

You can count on us for all of your security needs, including the design, installation, servicing and monitoring of your Security ONE Alarm system.

Local ULC Monitoring

Monitored in Southwestern Ontario.


Monitored in Southwestern Ontario by our own ULC-Listed emergency care center professionals.

We don’t outsource the monitoring of your alarms to 3rd party call centers out of the country. Our SIA (Security Industry Association) Certified care operators are on site 24/7 to handle all emergency calls and alarms.

Because we own and operate our own monitoring center – we can customize, monitoring and dispatch commands to best suit the needs of all our clients.  Our operators have an extensive understanding of your communities and streets, because they live local. Local Matters!

Professional Installation

Over 100 Years combined technical experience


Our technicians are all ULC and CANASA (Canadian Alarm Association) Certified. 

We personally install what we sell.  We are not a “third party” Alarm Company.”  Our technicians are not only trained to the highest of standards on installations, they also add a layer of knowledge when positioning all the components of your security system.  This again ensures that there are no vulnerabilities in your system.

When our technicians leave your home or business you will be setup and secured.  Our station will then ensure that your system is transmitting properly, each and every day.

Full Service Security

Chosen by Honeywell as an Authorized Dealer


We can integrate security alarms, medical alarms, access control, and video surveillance into one complete system.

Whether your home or business requires a basic security system, or a very complex multi system design, Security ONE has the expertise and experience required to provide a safe, secure and affordable solution.

We take great pride in participating in community events, events that give back to our communities.  For the past 2 years we have provided a family with a FREE security system with FREE monitoring!  This is a highlight of the year for many of our team.  We look forward to continuing this tradition.


Client Testimonials

“We found out that at least 4 houses on our street were broken into while the owners were sleeping inside. I’m guessing everyone else on our street wishes they had an alarm system right about now. This is now the second time that our house has had an attempted break-in. Because of our home alarm system, our house has never actually been illegally entered. I just wanted to let you know and send you a quick note of thanks!! “

– Billie Stapleton – Kingsville

“Security ONE has been a wonderful company to deal with. Everything from our initial quote, to the unobtrusive installation has been nothing short of excellent. The security we now have far outweighs the minimal monthly expense that we pay for this service. We would definitely recommend Security ONE for their customer service, quality, and affordability.

– Frank & Emily Gabbana – Windsor

“I would like to say thank-you to Security ONE for the wonderful service and installation of my home alarm system. I was very pleased with your Security Consultant (Debbie Jacques). I received other quotations from a few companies, and one was lower in price. However, I found Debbie Jacques very knowledgeable and thorough in educating me about the product and felt more comfortable using Security ONE. “

– Barb Mayea – Windsor

“I just want to thank you for the terrific service my husband, Gordy Cooper, and I received from you with respect to purchasing an alarm system. Now that we have our alarm, he cannot believe the “peace of mind” it brings him. Your service and knowledge were the selling points in us having an alarm installed and making us feel safe, with at home or away!”

– Tracy Panchuk – Windsor

“Our insurance company told us we needed to install a sump pump/water bug sensor. We contacted Security ONE and they came and installed water bugs and a sump pump detector. They work great! We had a water issue when the upstairs toilet overflowed, the water bugs detected it and Security ONE called. It was a life saver! Thank you!

– Linda Enns – Leamington
