We built the firm we wished we'd had as business owners.
McRally Professional Corporation is a Calgary-based CPA firm founded on a simple idea: financial advice lands differently when it comes from someone who has actually run a business. Our work is why owners across Alberta trust us with the numbers behind their livelihoods.
Our story
McRally Professional Corporation is a Chartered Professional Accountant firm based in Calgary’s Inglewood-Ramsay corridor, built around a gap we kept seeing: business owners between $350K and $10M in revenue are too big for a shoebox-and-spreadsheet setup, but too small to justify a full-time CFO. So they end up with compliance-only accounting – books filed, taxes submitted, and no one actually helping them run the business.
What sets us apart isn’t just credentials – it’s experience. We’ve sat on both sides of the table: as chartered professional accountants, and as business owners making payroll, managing cashflow, and living with the consequences of financial decisions. When we tell you a hire is premature or a tax structure is costing you money, it’s not theory. It’s pattern recognition from having carried the same weight.
That dual perspective shapes everything about how the firm runs. We keep engagements hands-on and senior-led. We give straight answers even when they’re not the ones you were hoping for; we’d rather lose a pitch than soften a number. And we build every engagement to grow with the client, from foundational bookkeeping through to full CFO-level strategy, so you’re never forced to switch firms just because your business got bigger.
Today we serve owners across all of Alberta, with an expansion to Vancouver planned for early fall 2026. Beyond client work, we also run Quantum Transformation. It’s a coaching course for other accountants — because raising the standard of advice in this profession benefits everyone who relies on it.

Leslie Ly, CPA
Leslie works closely with business owners to bring clarity to their numbers and turn financial information into practical decisions. Whether it’s understanding cashflow, improving reporting, building a forecast, planning for taxes, or evaluating the next opportunity, his focus is on helping owners understand what the numbers mean, why they matter, and what to do next.
At McRally, Leslie takes a hands-on approach to financial advisory, working alongside clients as their businesses evolve and grow. He believes good financial advice shouldn’t make things more complicated. It should give owners a clearer picture of their business and the confidence to make better decisions.

He brings that technical foundation together with a practical, straightforward approach to helping businesses build stronger financial foundations.
What makes us different
Years of hands-on accounting and CFO work across a range of industries, not just theory. We’ve seen enough businesses from the inside to know which problems are normal, which are urgent, and which are about to get expensive.
You get direct access to the people doing the work, not a rotating cast of junior staff. Your questions get answered by someone who knows your file, your history, and your goals, usually the same day you ask.
Straight answers about what your numbers actually mean, even when it’s not what you want to hear. If a plan doesn’t hold up financially, we say so before you commit – not after it costs you.
As business owners ourselves, we understand the pressure behind every financial decision you make. Payroll deadlines, slow receivables, growth bets – we’ve navigated them in our own business, not just advised on them.
From trades to tech, we work across sectors, bringing broad pattern recognition to your numbers.
Our support scales as you do – from foundational bookkeeping to full CFO strategy. Crossing $2M in revenue shouldn’t mean finding a new firm; it means your existing partner shifts gears with you.
OUR PLATFORM PARTNERS
A typical McRally client
Owner-led businesses, $350K to $10M, any industry
Our clients don’t share an industry. They share a situation: owner-led companies generating $350K–$10M in revenue, often using Xero or QuickBooks Online, and looking for more than someone who simply prepares the books.
Across industries, the financial questions are often the same. What changed this month? Where is the cash going? What should you be watching? We work with you to understand what the numbers are telling you and give you straightforward answers you can act on.
