About us


Systèmes de Support Informatique (SSI) was founded in 1983. At that time, the company’s goal was to offer innovative and customized solutions to solidify and secure mechanical and electrical infrastructures for IT environments. This is what it has been doing since its inception and is what has earned the company’s reputation in the field. 

In 1987, SSI became the leading distributor of Mitsubishi uninterruptible power supply (UPS) systems for sale and service in Canada. 

Located in the town of Saint-Laurent in the Montreal region, SSI covers a large area and the team operates across the whole of Quebec. Its expertise in the implementation of custom-built uninterruptible power supply (UPS) systems has developed over the years of operation. Its systems are reliable, innovative, and its customer service is exemplary. Since 1983, SSI has successfully deployed and still maintains close to a thousand UPS systems.

The company holds several licenses and certifications, granting it impressive credibility. It is also ETL and ISO 9001 certified.

Also, every member of the team of technical professionals has received detailed training on the products and their maintenance.
