The 50 largest Accounting companies in Canada (2026 list)

These Canadian accounting firms include large national networks and professional bodies, alongside regional and specialized firms. MNP offers national accounting, tax, and business consulting. Chartered Professional Accountants of Canada supports Canadian CPAs through regulation and development. Baker Tilly Canada provides audit, tax, and advisory solutions via an independent member network, while RSM Canada offers assurance, tax, and consulting services globally.

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.
