About A&P
About Our Accounting Firm in London, Ontario
A&P Accounting & Tax Experts is an incorporated accounting and tax practice in the core of downtown London. We exist for a simple reason: people want a real accountant they can sit down with, ask questions of and call again when the CRA writes, rather than a seasonal storefront or an app.
Our clients include salaried employees and students, landlords, sole proprietors, incorporated owner-managers and executors handling a family estate. The work spans personal and corporate tax, bookkeeping, payroll, HST and CRA correspondence.
Every review on our Google profile is five stars, 11 so far, and the same three themes come up in them: clear explanations, careful attention to detail and fast responses.

Why we do this
Our Story

A&P was built around a gap we kept seeing in London. Walk-in help at the CRA tax services office on Talbot Street is limited, many seasonal tax shops close in May, and large firms are rarely set up for a family with one rental unit or a contractor in his first year.
So we set up in a downtown office tower, kept Saturday hours for people who work weekdays, and made one rule non-negotiable: nobody signs a return until they understand it. That review conversation is often where missed credits and wrong assumptions surface.
Being a few blocks from the CRA office and at the centre of the city also means clients from every London neighbourhood, and from towns along Highways 4, 401 and 402, can reach us easily or skip the trip and work online.
The work covers everything from personal tax returns for London families to T2 corporate returns for owner-managed companies.

Our working style
How Our Team Works
Credentials matter, but what clients feel is how a firm works day to day. You deal with people who know your file, deadlines are tracked from the first call, and nothing sits forgotten in a pile until the week before it is due.
These habits are what clients tend to mention in their reviews, and they apply to every file we take on.
Plain-Language Reviews Before Anything Is Filed
We walk you through the result line by line in person, by phone or on video. You learn why the refund or balance is what it is, and what would change it next year.
Detail Checked Against Your CRA Records
With your authorization, we can see the slips employers and banks filed with the CRA, which helps catch a forgotten T5 or T4A before the CRA's matching program does.
Quick, Direct Answers
Questions get answered by phone during office hours, Monday to Saturday. Responsiveness is one of the most common things clients mention about working with us.
Support That Continues After April 30
Review letters, reassessments and instalment reminders arrive all year. We read them with you and handle the reply, so you are never left decoding CRA language alone.
What you can check
Credentials, Software and Scope of Practice
When you compare accounting firms in London, Ontario, look past the logo wall and ask what the firm actually does, which tools it works in and what past clients say. Here is our honest answer to each.
Accounting and Tax Specialists
We prepare personal, trust and corporate tax returns, keep books, run payroll and prepare financial statements under compilation engagements (CSRS 4200), the standard for most private companies.
In Canada, anyone may prepare tax returns, while the CPA title is protected. If you are looking for a CPA in London, Ontario specifically, you can confirm any member or firm in the CPA Ontario public directories.
Software We Work In
Bookkeeping is done in QuickBooks Online or Xero, whichever suits your business, with bank feeds reconciled each period. Returns are filed electronically through the CRA's EFILE and corporate internet filing systems.
Documents move through a secure client portal, and authorizations are signed by e-signature.
What Our Google Reviews Say
We hold a 5.0-star rating from 11 Google reviews, all five stars. Reviewers return to clear explanations, attention to detail and quick replies.
Privacy and security
How We Protect Your Financial Information
Your files are shared only through our secure portal or in person, and only the people working on your file see them. Your SIN, slips and bank statements are some of the most sensitive documents you own, so we treat access to them as narrowly as possible.
Secure Client Portal and E-Signatures
Instead of unprotected attachments, documents are uploaded to a secure client portal where you and our team can both see what has arrived.
Forms like the T183 e-filing authorization are signed electronically, so nothing sensitive needs to travel by paper.
CRA Represent a Client Authorization
To speak with the CRA or view your account, we ask you to authorize us through the CRA's Represent a Client service. Level 1 lets a representative view information; Level 2 also lets them request changes on your behalf.
You confirm the request in your CRA My Account and can cancel it any time, online or by phoning the CRA. Businesses manage the same access through My Business Account.
Record Retention
The CRA generally requires you to keep tax records and supporting documents for six years from the end of the tax year they relate to.
Copies of what we file and the documents behind each return stay in your client file, so a question about an earlier year can be answered without you digging through boxes.
