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.

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
