Kenway Mack Slusarchuk Stewart

What Kenway Mack Slusarchuk Stewart does

Kenway Mack Slusarchuk Stewart (KMSS) is a privately held chartered professional accountant (CPA) firm headquartered in Calgary, Canada. Founded in 1986, the firm provides a multi-disciplinary professional services offering that spans accounting, audit, consulting, and tax planning. Its service breadth positions it as a full-service mid-market accounting practice serving clients that require assurance work alongside recurring compliance and advisory support.

The firm operates with 51–100 employees, placing it in the small-to-mid-tier of Canadian CPA practices by headcount. Its ownership and governance structure is consistent with a multi-partner professional services model, though specific partner identities, ownership splits, and management roster are not disclosed in the available data. The firm's website (kmss.ca) is its primary digital presence; most enrichment sources returned bot-verification screens rather than substantive firmographic content, which limits publicly retrievable detail on client roster, sector mix, engagement models, and partner-level governance.

The business model follows standard CPA firm economics: revenue is generated through fee-for-service engagements (hourly or fixed-fee) across audit, tax, accounting, and consulting lines. The firm does not appear to be venture-backed, does not operate a technology product, and does not disclose pricing, packaged service offerings, or technology platform details. There is no evidence of geographic expansion beyond Calgary, no subsidiary structure, and no disclosed M&A, capital raising, or strategic transaction activity in the supplied data.
