about

Meet Purvish Shah, CPA, CA

Purvish Shah is the founder and principal of Adian Professional Corporation. He holds the CPA, CA designation and a Master of Accounting from the University of Waterloo — one of Canada’s most respected accounting programs. Before founding Adian, Purvish trained and worked at a Big 4 public accounting firm, where he developed the technical foundation and professional rigour that informs every engagement at this firm.

Purvish’s practice focuses exclusively on incorporated businesses and CCPCs operating under the Canadian Income Tax Act. His work spans T2 corporate tax return preparation, CSRS 4200 compilation engagements, and structured tax planning for shareholders facing material tax decisions — corporate reorganizations, LCGE planning, post-mortem planning, and trust and estate structures.

He does not delegate client work. When you engage Adian Professional Corporation, you work directly with Purvish. The level of attention you receive reflects the background and experience described above — not a tiered service model where senior credentials are sold and junior execution is delivered.

How We Work

Every engagement at Adian Professional Corporation follows the same principles regardless of the complexity of the work:

Principle What It Looks Like in Practice
Scope confirmed in writing before work begins Engagement letter issued for every engagement. Fee confirmed. No work starts without written agreement. No hourly billing, no surprise invoices.
Senior CPA on every file Purvish prepares and reviews every return personally. Client work is not delegated to staff or outsourced.
Technical accuracy is non-negotiable We apply the current Income Tax Act provisions, CRA administrative positions, and professional standards to every engagement. We do not guess and we do not cut corners.
We tell you when we are not the right fit If your situation is outside our scope — Quebec provincial filings, US tax, international structures, or a matter that requires specialist counsel — we tell you at the outset and refer you appropriately. We do not take on engagements we cannot execute properly.
Written deliverables for planning work Tax planning engagements produce a written plan with ITA section references. Verbal advice is not our product.

Who We Work With

Our client base is incorporated businesses and their shareholders operating under the Canadian Income Tax Act. We do not serve clients with US tax obligations, foreign income, or international structures.

We serve clients in all Canadian provinces and territories except Quebec. Our office is in Mississauga, Ontario. All engagements are conducted remotely.
