What Koff & Associates does

Koff & Associates is a financial services firm based in Markham, Ontario, Canada, founded in 1994 and operating with 1–10 employees. The firm offers compliance, audit, investment advice, wealth management, retirement planning, and insurance services to clients in the Greater Toronto Area and surrounding markets. Its service portfolio, as reflected in the successor firm's public materials, spans tax planning and compliance (including R&D incentives, indirect tax, US corporate tax, cross-border personal tax, international tax, succession and estate planning, and transfer pricing), assurance and audit (ASPE, IFRS, NPO and public sector accounting), risk management (governance/risk/compliance, internal audit, SOX certification, third-party assurance), advisory (transactions, restructuring, forensics, cybersecurity, consulting), cloud-based accounting, Indigenous services, ESG and sustainability advisory, and family business services.

The firm operates on a fee-for-service professional services model typical of Canadian accounting and advisory practices, with pricing not publicly disclosed and engagements offered on a quote basis. Distribution is via direct client engagement; a client portal supports ongoing service delivery. The technology stack centers on cloud accounting solutions and a client portal positioned as an ease-of-use differentiator.

The defining structural event for the firm is its integration into Doane Grant Thornton LLP, a Canadian member firm of Grant Thornton International Ltd that employs 3,000+ colleagues across 70+ Canadian offices with 85+ years of legacy. Founder Michael Koff is listed in the leadership record, suggesting continuity through the transition. Post-integration, the firm is positioned within a national platform serving Canadian businesses, not-for-profit organizations, Indigenous communities, and family businesses across tax, assurance, advisory, and risk services.
