Our History

Since its establishing in the Nickel Capital of the world (Sudbury, Ontario) in 1995, SSI- Sonmar Security Inc. has been a leader in business security, camera surveillance, and all low voltage electronics. From our revolutionary control panels, to our industry-leading IP alarm systems and now our High Definition IP camera surveillance, SSI has always been front and center in the security field.

SSI flourished in the community through developing a reputation for providing excellent customer service. We did this through the acquisition of many well‐known and highly frequented businesses’, such as The New Sudbury Shopping Center, Tim Hortons, The Canadian Revenue Agency and the Sudbury Catholic School Board.  In time, SSI needed to expand to meet the new demand for the brand, and hired more technicians, administrative staff and added locksmith services to our expanding business.

Our customers desired our customer service to the extent that they began asking us to branch out and help them in other areas. In turn, through additional, extensive research and training, we expanded into other areas and became leaders throughout Ontario in residential/business security, access control, audio/visual, integration/automation and networking solutions. Shortly after this expansion, SSI began to see their customer base grow even outside the boundary of Sudbury. We were now serving customers in Timmins, North Bay, Sault Ste. Marie, Barrie, Toronto (GTA) and beyond, just through word of mouth with no advertisement in these areas. We knew, that the only way Son‐Mar could maintain its high level of customer service, was to branch out at a higher level into those communities; it was time to expand again.

In 2012, the owners of SSI began lengthy discussions about how we would expand at this larger scale, yet still ensure new members of our team would hold the integrity of the SSI name. We realized that what brought us to where we were, was the reality that as owners, we worked harder for our clients, and the harder we worked on this, the more successful we were. The only way this could truly happen for the new team, was if they too became owners themselves, and the idea of offering the Dealer Program opportunity came to be. This was our opportunity to create an Ontario‐wide integration company.

With our trusted network of dealers throughout the country, SSI is equipped to suit every Commercial and Industrial need.  We know that security service is not the same for every customer, that is why we custom design each security and locksmith system to make your business perform efficiently, providing you and your employees a secure and safe environment to work.
