Our History


Security One Support

Providing peace of mind since 1978.


Security ONE has come a long way since our humble beginnings in 1978. Set up by group of partners with an extensive background in security, the company remains locally owned and operated to this day.

With its origins in the basement of a house on Erie St in Leamington, ON, the company’s head office remains in the tomato capital of Canada. For many years, Security ONE operated out of an office on Oak St, when it expanded to include a branch office in Windsor, ON, and eventually Chatham, ON.

Security ONE moved its head office operations from Oak St to our current location on Sherk St, in Leamington, into the former agricultural testing facility for the H.J. Heinz Company. That same year saw the company’s latest expansion into London, ON.

With a team of nearly 50, Security ONE serves customers across Southwestern Ontario and beyond.
