Most business owners who are unhappy with their accountant already know it. The fees keep coming, the responses get slower, and somewhere along the way the relationship stopped feeling like a partnership and started feeling like a subscription you forgot to cancel.
The thing that keeps most people from making a move isn’t satisfaction — it’s the assumption that switching is going to be messy. What happens to the files? Will there be a gap? Is this going to be awkward? In practice, a well-run transition is none of those things.
First — Your Data Belongs to You
This is the most important thing to understand before you do anything else. Your financial records belong to your business. Full stop. A professional firm cannot hold your data hostage — regardless of how the relationship ended or whether there’s an outstanding balance. Your tax returns, payroll history, and general ledger are your property.
One distinction worth knowing: your accountant technically owns their internal working papers — their notes, internal spreadsheets, and calculations. You don’t need those. What you do need is the Trial Balance and the Adjusting Journal Entries. That’s the information a new firm needs to pick up exactly where things left off.
Your data includes: financial statements, the general ledger, all corporate tax returns and CRA correspondence, and full admin access to your accounting software — QBO, Xero, Dext, or whatever platform you’re on.
Before You Send Any Emails — Do This First
Log into your accounting software and export a full General Ledger and Aging Report to a CSV file. Save it somewhere you control. This takes about five minutes and gives you a hard backup of exactly where things stood the moment you decided to make a change.
You Don’t Have to Manage This Yourself
This is the part most owners don’t realize: your new firm should lead the handoff, not you. In Canada, when a business switches accounting firms, the new firm initiates what’s called Professional Clearance. They reach out to the previous firm directly, handle the technical handoff, and manage the professional dialogue. Your job is to sign the engagement letter and give the new firm permission to make contact. They handle the rest.
The Steps That Actually Matter
Step 1 — Sign with the new firm first
Never give notice to your current accountant until the new engagement letter is signed. You want zero gap between relationships.
Step 2 — Send a short, professional notice
No long explanations. No venting. A brief, factual email that the relationship is ending and that a new firm will be in touch regarding the file transfer.
Step 3 — Clear any outstanding balance
If you owe the previous firm money, pay it before initiating the transfer. An unpaid balance gives them a reason — and sometimes a legal basis — to delay releasing your files.
Step 4 — Update your CRA authorization
Log into your CRA My Business Account and revoke the previous firm’s access. Then grant the new firm Level 2 or Level 3 authorization so they can communicate with the CRA on your behalf. This step gets forgotten more often than it should.
Step 5 — Tell your bank
If you have a commercial loan or a line of credit, let your lender know about the transition. Some commercial lending agreements require notification when your financial advisors change. A quick heads-up prevents an unnecessary review of your loan covenants.
You Don’t Have to Wait for Year-End
A lot of owners talk themselves into waiting — for the fiscal year to close, for tax season to pass, for some cleaner moment that never quite arrives. There isn’t one. Mid-year is actually a better time to switch than most people think. A new firm that comes in with six or eight months left in your fiscal year has time to review what’s there, fix what needs fixing, and build a proper plan before year-end pressure hits.
