These Ontario-based companies operate primarily in financial services, human resources, and technology, with a strong presence of mid-sized firms. For example, Wealthsimple simplifies investing, EQ Bank offers high-interest banking, and Propel Holdings provides fintech credit solutions. Canada Job Bank connects job seekers with recruiters, while Mechanical Jobs and Career focuses on mechanical engineering opportunities. Voices is a marketplace for voice actors, and Clutch is an online used car retailer.
A notable pattern is the concentration of headquarters in Toronto, indicating a central hub for online businesses in the province. Many of these companies were founded in the 2010s, reflecting a recent surge in online service and technology ventures.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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 12, 2026.
