About
About Greywood Advisory
Who We Are
A Personal Tax Practice
in London, Ontario
Greywood Advisory is a personal tax preparation and advisory firm based in London, Ontario. We work with individuals who want their taxes done right: filed accurately, priced transparently, and handled by someone with the expertise to manage it properly.
Who Is Behind It
Founded by
a CAF Veteran
Greywood Advisory was founded by Tyler, a 16-year veteran of the Canadian Armed Forces, including an overseas deployment. He served as a Human Resources Administrator, the trade that handles military pay and records, and is completing a Bachelor of Commerce in Accounting at Thompson Rivers University. That history doesn't make for a more interesting bio, but it makes for a more disciplined practice. Deadlines are real. Details matter. Work gets done.
That same standard carries into every return we prepare, and that history is why military members, veterans, nurses, and first responders receive a 15% service appreciation rate here.
Why We Exist
Two Options.
Neither Quite Right.
Most people in London have two real options at tax time: a national chain that processes returns at volume, or an accounting firm where a personal T1 isn't exactly a priority. Neither option feels quite right, and for a lot of people, it isn't.
Greywood was built to fill that gap. You get dedicated, competent service on your personal return, at a price you know before you commit.
What We Believe
Simple to Do.
Hard to Do Well.
Tax preparation isn't complicated to do: it's complicated to do well. The difference is in what you claim, what you don't, and whether the person preparing your return understands your situation or is just entering numbers into a form.
Your return deserves the same care you'd expect from any professional service. That means asking the right questions, knowing the rules, and filing a return you can stand behind.
Based in London
Built for
the Long Term
We meet clients in person in London and work by video and phone across Ontario and the rest of Canada: same care, same fees, wherever you file from.
Greywood Advisory is being built for the long term, not a side project, not a seasonal pop-up. The clients we take on now are the foundation of what this practice becomes.
If that sounds like the kind of firm you want handling your taxes, we'd be glad to work with you.
Our Approach
How We Work
Document-First Preparation
We review every slip, statement, and supporting document before preparing your return. Nothing is estimated or assumed: accuracy starts with the source material.
Fixed Fees, Agreed in Advance
Your fee is confirmed before any work begins. You'll never receive an invoice that surprises you, and you'll never be billed extra for asking a reasonable question.
One Adviser, Always
You communicate directly with the person preparing your return. Not a call centre, not a junior staff member, not an automated email queue. Your situation is known, remembered, and handled by one professional throughout.
Deadline Ownership
We track every relevant CRA deadline for you: April 30, June 15, instalment due dates. If you engage us with enough lead time, your return is filed before the deadline. That is not a promise we've ever had to walk back.
Direct Answers, Plain Language
Ask a question, get an answer you can actually use: what it means for your return, in plain terms, without a billing meter running. If something in your file looks off, we raise it with you before we file, not after the CRA does.
We Stay on Your File
Filing isn't the finish line. We check your notice of assessment when it lands, prepare adjustment requests when something changes, and, with your signed authorization through the CRA's Represent a Client service, respond to CRA reviews on your behalf, so a brown envelope never ruins your week.
The Work Itself
What We
Actually Do
Personal, corporate, and trust returns, crypto reporting, and the bookkeeping and payroll that keep the records clean in between — the full personal and small-business tax cycle, handled by one person.
The services page sets out each one, and the fee calculator gives you the number before you commit.
