What Welch LLP does
Welch LLP is a privately-held Chartered Professional Accounting Limited Liability Partnership founded circa 1918, headquartered in Ottawa, Ontario, with 12 offices spanning Eastern Ontario, the Ottawa Valley, the Quinte region, the Greater Toronto Area, and the Outaouais region of Quebec. The firm operates a full-service accounting, audit, tax, and advisory practice serving owner-managed businesses, not-for-profit organizations, government and public sector entities, family offices, manufacturers, and an expanding roster of verticals that now includes SaaS companies, Indigenous businesses, and media/entertainment clients. Bilingual service delivery is provided through the Lévesque Marchand Welch SENCRL entity in Gatineau, and international client needs are routed through the firm's BKR International network membership.
Revenue is generated almost exclusively through professional services fees across five intertwined streams: Assurance and Accounting (audit, review, compilation), Tax Services (corporate, personal, trust/estate, cross-border, SR&ED), Business Advisory (M&A, due diligence, family office, business incentives), Client Accounting Services (bookkeeping, back-office, controllership), and Digital Services (technology risk, cybersecurity, digital transformation). Pricing is engagement-based and not publicly disclosed. Go-to-market is relationship-driven and localized, with each office staffed by dedicated partners serving community clients, supplemented by a content/thought-leadership engine (Insights blog, webinars, tax memos), CPA student recruitment at regional universities, and active community involvement anchored by the Welch Community Foundation.
The firm employs between 501 and 1,000 staff and partners, has no proprietary technology platform, no external private equity or parent ownership, and has shown continued organic expansion signals in 2025-2026 including new partner promotions, a SaaS industry launch, active hiring in Ottawa, and a digital/cybersecurity advisory practice under specialized partner leadership. Award recognition (CPA Ontario 2024 Fellow, Governor General's Curling Club induction) and Canadian institutional standards expertise (former Public Sector Accounting Board staff on partner roster) anchor credibility for public sector and NPO engagements.
