The Perseus Group, part of Constellation Software, focuses on nurturing businesses with data-driven guidance. Sofina Foods Canada is a prominent manufacturer of various meat and fish products. The presence of several major software development companies, such as Enghouse Systems and Jonas Software, indicates a strong technology cluster in the area.

## How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
