Segal GCSE

What Segal GCSE does

Segal GCSE LLP is a Canadian limited liability partnership headquartered at 10 York Mills Road, Toronto, that provides professional services in assurance and advisory, tax, transaction advisory, transfer pricing, valuations, outsourced accounting, business advisory, and penetration testing. The firm was formed effective July 1, 2022 through the merger of Segal LLP (founded 1976) and GCSE LLP (29+ years of prior operating history), and together they now operate as one of the largest independent firms in the Greater Toronto Area, with 35 Partners and over 275 audit, accounting, tax and advisory professionals. Client segments span owner-managed businesses and entrepreneurs, high-net-worth individuals, multinational enterprises with Canadian operations, OSC/IIROC/MFDA-regulated financial services firms, not-for-profits and registered charities, and professional corporations in legal and medical fields.

The firm delivers services through partner-led engagement teams using standard professional services technology — Citrix ShareFile for secure client document exchange, QuickBooks Online for outsourced accounting and bookkeeping clients, and the Aiwyn portal for invoicing and payments — rather than proprietary software products. International reach is enabled through membership in Moore North America and the Moore Global Network, while specialized capabilities such as penetration testing are delivered through a partnership with The Bonadio Group's Enterprise Risk Management Division. The firm markets primarily through its website insights, the annual Tax Series for Accountants professional education program, an annual "In Touch with Tax" publication, and a LinkedIn/Instagram presence.

Revenue is generated exclusively through engagement-based professional services billing, with fees determined by scope, complexity and professional time on multi-year client relationships covering recurring audit, tax compliance, transfer pricing, transaction support and advisory mandates. Pricing is not publicly disclosed and there are no software/SaaS or productized revenue streams; the firm operates a single-country (Canada) delivery model with cross-border capacity accessed through the Moore Global affiliation and partnerships. The firm has been recognized by Inside Public Accounting as a Best of the Best Firm in 2017, 2018, 2019, 2020 and 2024.
