Why your credit report matters before a mortgage application
When you apply for a mortgage, your lender reviews your full financial picture. According to the Financial Consumer Agency of Canada, a lender or mortgage broker looks at your assets, income, and debt, and will typically request identification, proof of employment, proof of funds for the down payment and closing costs, and details about any existing financial obligations. Your credit report sits at the centre of that review: it tells lenders how reliably you have managed debt in the past.
An error on your report, whether it is a payment incorrectly marked late, a balance that does not reflect what you actually owe, or an account that belongs to someone else entirely, can lower your credit score and affect the terms a lender is willing to offer. Catching and correcting those errors before you submit a formal application is one of the most practical steps you can take to make sure your file reflects your true financial situation.
Common types of errors to look for
Not every mistake on a credit report is obvious. Some errors are straightforward, while others require careful comparison with your own records. Here are the most frequent categories to watch for:
- Wrong account status: A loan or credit card that you paid off in full may still appear as open or in collections. This can inflate your apparent debt load.
- Incorrect payment history: A payment you made on time may be recorded as late or missed. Even a single entry like this can drag your score down noticeably.
- Inaccurate balances or credit limits: If a reported balance is higher than your actual balance, or a credit limit is shown as lower than it really is, your utilization ratio will look worse than it is.
- Duplicate accounts: The same debt may appear more than once, making it seem as though you owe more than you do.
- Identity or fraud-related entries: Accounts you never opened, addresses you never lived at, or inquiries you never authorized can signal that someone else has used your information.
Reviewing your report carefully, line by line, is the only reliable way to catch these issues before a lender does.
How to obtain and review your credit report in Canada
In Canada, the two main credit bureaus are Equifax and TransUnion. Both are required to provide you with a free copy of your credit report upon request. You can request your report by mail, online, or by phone, depending on the bureau. It is worth requesting both reports, since lenders may check one or both, and the information they hold is not always identical.
When your reports arrive, compare each entry against your own records: bank statements, loan agreements, and payment confirmations. Note any discrepancy, no matter how small it appears. Keep a written log of what you find, including the account name, the reported information, and what you believe the correct information to be. This log will become the foundation of your dispute.
General guidance consistently encourages reviewing credit reports for errors well before a mortgage application, so that any corrections have time to be processed and reflected in your score. Starting this process several months before you plan to apply gives you the most flexibility.
The formal dispute process with Canadian credit bureaus
Once you have identified an error, you can file a dispute directly with the credit bureau that is reporting the incorrect information. Both Equifax and TransUnion have formal dispute processes available online, by mail, and in some cases by phone. Here is how the process generally works:
- Gather your supporting documents. Collect any evidence that supports your position: a bank statement showing a payment was made on time, a letter from a creditor confirming an account was closed, or a fraud report if the entry is not yours at all.
- Submit your dispute in writing. Clearly identify the entry you are challenging, explain why it is incorrect, and attach copies (not originals) of your supporting documents. Keep a copy of everything you send.
- Wait for the investigation. The bureau is required to investigate and respond within a set timeframe. During this period, the bureau contacts the creditor or lender that reported the information and asks them to verify it.
- Review the outcome. If the bureau confirms the error, the entry will be corrected or removed. If the creditor insists the information is accurate and you still disagree, you have the right to add a consumer statement to your file explaining your position.
Correction timelines vary. Simple errors may be resolved within a few weeks; more complex disputes, particularly those involving fraud, can take longer. Confirm current timelines directly with the bureau when you file.
Timing your dispute around your mortgage application
Before shopping for a property, it is worth clarifying your financing situation and understanding what documents a lender will request. If you know a dispute is pending, it is generally better to wait for the correction to appear on your report before submitting a formal mortgage application. A corrected report gives your lender an accurate picture of your credit history from the start.
If you are already in the application process and discover an error, inform your mortgage broker right away. In some cases, a lender will accept a letter from the credit bureau confirming that a dispute is under review, or a letter from the creditor acknowledging the error. Your mortgage broker can advise you on what documentation a specific lender is likely to accept and how to present your file clearly.
Keeping thorough records throughout the dispute process, including correspondence with the bureau and any responses from creditors, means you will have everything on hand if a lender asks questions. Learn more about how a mortgage broker can help you prepare your application file.
Working with a mortgage broker during the process
A mortgage broker can be a practical resource when you are navigating credit report issues alongside a home purchase. Because brokers work with multiple lenders, they are familiar with how different institutions weigh credit history and what kinds of documentation they accept when a dispute has been filed or recently resolved.
Your broker can also help you understand how your overall financial profile, including your income, assets, and existing obligations, fits together in a lender's assessment. This broader view can be useful if a credit error has temporarily affected your score and you want to understand how the rest of your file is positioned.

The essential takeaway
Disputing credit report errors takes time and documentation, but addressing inaccuracies before you apply for a mortgage means your lender sees an accurate picture of your financial history. Start by requesting your reports from both Canadian credit bureaus, compare every entry against your own records, and file a formal dispute with supporting documents for anything that does not match. Give yourself enough lead time so that any corrections are reflected before your application is submitted. A mortgage broker can help you understand how your full file reads to a lender and guide you through presenting your situation clearly.

Frequently Asked Questions
Should I dispute errors on both my Equifax and TransUnion reports, or just one?
It is worth checking and disputing errors on both reports. The two bureaus hold information independently, so an error may appear on one and not the other. Since a lender may pull either or both reports during a mortgage review, correcting inaccuracies on each one ensures your full credit picture is accurate no matter which bureau is consulted.
What documents should I gather before filing a credit report dispute?
Collect any records that directly contradict the error: bank statements showing a payment was made on time, a letter from a creditor confirming an account was closed or a balance was paid, or a fraud report if the entry is not yours. Send copies only, never your originals, and keep a full copy of everything you submit, including your written dispute letter and any attachments.
What does a lender actually look at when reviewing my mortgage application?
When preparing a mortgage application, a lender or mortgage broker looks at assets, income, and debt, and may request identification, proof of employment, proof of funds for the down payment and closing costs, and information about debts or financial obligations.
How far in advance should I start reviewing my credit report before applying for a mortgage?
Starting several months before you plan to apply gives you the most flexibility. Disputes take time to investigate and for corrections to be reflected on your report. The earlier you begin, the less likely a pending correction will overlap with your formal application, which helps your lender see an accurate picture of your credit history from the outset.
What can I do if a dispute is still pending when I am ready to apply for a mortgage?
Let your mortgage broker know right away. In some cases, a lender will accept a letter from the credit bureau confirming that a dispute is under review, or a letter from the creditor acknowledging the error. Your broker can advise you on what documentation a specific lender is likely to accept and how to present your file as clearly as possible given the circumstances.
