Half of them were founded in 1981 or later. The most common headquarters are Toronto (7), Calgary (5) and Montreal (5).
This selection of large accounting and financial services firms in Canada includes companies like KPMG Canada, which provides audit, tax, and advisory services, and MNP, a national accounting, tax, and business consulting firm. Other prominent firms are PwC Canada, offering audit assurance and consulting, and BDO Canada, known for its assurance, tax, and consulting services.

## 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.
