Who We Are
Your Trusted Accounting Partner in Canada and Beyond
R.A. Mirza Professional Corporation is a boutique CPA firm built on a simple belief: that growing businesses and professionals deserve the same calibre of accounting and advisory expertise as large corporations — delivered with the personal attention that only a boutique practice can provide.
The firm was founded by Rizwan Mirza, a Chartered Professional Accountant holding designations in Canada, the United States, and the United Kingdom. Rizwan brings a rare combination of international credentials, cross-border expertise, and hands-on involvement with every client file. When you work with R.A. Mirza Professional Corporation, you work directly with Rizwan — not a junior associate.
We serve businesses, professionals, non-profit organizations, and cross-border clients across Canada and internationally, providing accounting, assurance, taxation, and advisory services that go well beyond compliance. Our goal is not simply to file your returns — it is to be a trusted financial partner who understands where you are going and helps you get there.
Our Mission
To provide growing businesses, professionals, and non-profit organizations with expert accounting, taxation, assurance, and advisory services — delivered with technical excellence, personal attention, and a genuine commitment to long-term client success. We measure our performance not by the returns we file, but by the outcomes we help our clients achieve.
Our Vision
To be the most trusted boutique CPA firm for growing businesses and professionals in Canada — known for our multi-jurisdictional expertise, our advisory-first approach, and the quality of the relationships we build. We aim to be the firm that clients recommend without hesitation, because working with us made a real difference to their business.
Our Values
Everything we do is grounded in four core values that define how we work and the standard we hold ourselves to:
• Integrity — We provide honest, transparent advice, even when it is not what a client wants to hear. Our clients trust us with their financial lives, and we honor that trust completely.
• Excellence — We hold ourselves to the highest professional standards in every engagement, from the accuracy of a T2 filing to the quality of a strategic advisory recommendation.
• Personalization — Every client is different. We take the time to understand each client's situation, goals, and industry before giving advice — so our guidance is always relevant, not generic.
• Partnership — We think of every client relationship as a long-term partnership. We are invested in your success, and we show that through consistent engagement, proactive communication, and advice that looks ahead.
Assurance & Advisory
Rigorous, standards-compliant assurance services — from review engagements to ASNPO reporting for non-profits.
Taxation
Corporate, personal, and cross-border tax services for Canada, the United States, and beyond.
Business Advisory
Strategic financial consulting, cash flow planning, incorporation, and profitability analysis to help your business grow.
Let’s Work Together
Why Choose Us?

Mirza Professional Corporation has the expertise, the credentials, and the personal commitment to support you. Contact us today to schedule a complimentary consultation.
Multi-Jurisdictional Expertise
Rizwan Mirza holds professional accounting designations in Canada (CPA, CA and CGA), the United States (CPA, Colorado), and the United Kingdom (ACCA). This breadth of qualification is rare in a boutique practice and gives our clients access to cross-border tax and advisory expertise that most local firms simply cannot offer. Whether your business operates in one country or three, we have the knowledge to keep you compliant and well-advised.
Advisory-First Approach
We do not just file returns and close the file. Our engagement with every client begins with listening — understanding your business model, your goals, your industry, and your challenges. From there, we provide practical, forward-looking advice that helps you make better decisions, plan ahead, and avoid costly surprises. Compliance is the floor, not the ceiling.
Personalized, Relationship-Driven Service
As a boutique firm, every client works directly with Rizwan. There are no account managers, no junior staff handoffs, and no rotating contacts. You receive consistent, senior-level attention from a CPA who genuinely knows your business — and who is available when you need answers, not just at tax time.
Industry-Specific Knowledge
We bring specialized knowledge to every sector we serve. From the nuances of professional corporation tax planning for physicians and consultants, to construction company accounting, to ASNPO-compliant financial statements for non-profits — our advice is always grounded in the real financial landscape of your industry, not a generic template.
