Spadina Security Incorporated (SSI) is a locksmith company specializing in Security Locks. We service the greater Toronto area (GTA) but focus in specific areas of the city, especially downtown Toronto. Electronic security has become a big part of what we do. Electronic locks with remote controls, access control systems and even camera systems are now part of our daily routine as well as installing deadbolt locks. Part of our job is to advise you, the purchaser, on the best product for your needs.
