The companies with mobile apps in Ontario are mostly large groups in banking and financial services, but also in retail, telecommunications, and hospitality. For example, TD, RBC, and Scotiabank are major financial institutions. Four Seasons operates luxury hotels globally, while Shopify provides e-commerce tools. Loblaw Companies is a large Canadian retailer.

A clear pattern is the strong concentration of headquarters in Toronto, with the majority of these large companies based there. Other significant headquarters cities include Ottawa and Brampton. This indicates a centralized corporate presence within Ontario.

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.
