# The 50 largest Accounting companies in Canada

Tamtam tracks 55 Accounting companies headquartered in Canada. This list ranks the 50 largest by number of employees on LinkedIn, led by MNP, Chartered Professional Accountants of Canada (CPA Canada) and Baker Tilly Canada. Their median headcount is 169. Half of them were founded in 1996 or later. The most common headquarters are Toronto (9), Calgary (6) and Montreal (6).

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.

A notable pattern is the concentration of headquarters in major urban centers. Toronto hosts several large firms, including CPA Ontario, which protects the public and advances the CPA profession. Montreal is home to FBL S.E.N.C.R.L., a prominent Quebec accounting firm, and Ordre des CPA du Québec, a professional organization with over 35,600 members.

## 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.
