What PSB BOISJOLI does

PSB Boisjoli is a Montreal-based accounting and professional services firm founded in 1930, historically devoted to the financial needs of small and medium enterprises. The firm operates as a partnership led by managing partners Kristina Ashqar and Frank Maselli, with a workforce of 30 partners/associates and over 200 employees delivering services from its boulevard Graham office in Montreal. Its core offering centers on accounting, certification, taxation, and advisory services for business clients.

Effective January 1, 2026, PSB Boisjoli joined Raymond Chabot Grant Thornton (RCGT) in what RCGT described as the largest consolidation of professionals in its history. Post-merger, the firm operates as part of RCGT while retaining its Montreal office, and clients gain access to more than 60 services spanning certification, taxation, management consulting, risk consulting, financial advisory, HR consulting, and restructuring and insolvency services. Through RCGT, the combined entity extends reach to the global Grant Thornton network spanning nearly 160 markets and approximately 100 offices across Quebec, Ottawa, and Edmundston, with specialized clienteles including bioalimentaire, cinema and television, retail, construction, manufacturing, municipal, public/parapublic, natural resources, and tourism sectors.

The business model is professional services fee-for-engagement: revenue is generated through direct delivery of accounting, tax, and advisory services by professional staff to business clients, primarily SMEs in Quebec. No technology platform, proprietary software, or AI/ML capabilities are disclosed for PSB Boisjoli itself. Pricing is not publicly disclosed, consistent with bespoke professional services engagements. The go-to-market is enterprise field sales delivered through office-based partner-led client relationships, now augmented by RCGT's broader regional and international distribution network.
