Does getting a mortgage pre-approval hurt your credit score?
A single pre-approval, run through one broker or lender, usually means one credit check on your file. Comparing several mortgage lenders inside a short window does not multiply that impact the way applying separately at five banks might. This page covers hard versus soft inquiries, what actually moves your score, and why skipping pre-approval to protect your score costs more than the inquiry itself.

Does a mortgage pre-approval hurt your credit score?
A single mortgage pre-approval does not meaningfully hurt your credit score. It typically involves one credit check, and multiple mortgage inquiries made within a focused shopping window are treated by scoring models as one event rather than several. The bigger cost sits with buyers who skip pre-approval and lose a property, a rate, or their negotiating position instead.
Buyers avoid getting pre-approved because they worry a credit check will damage their score before they even have an accepted offer. That fear is understandable, and it is largely misplaced. A pre-approval run through one broker or one lender produces a single credit check on your file.
The real financial risk runs the other direction. A buyer who skips pre-approval to protect their score often overpays, misses a favourable rate window, or loses a home to a buyer who was ready to close. One inquiry is a minor, temporary entry on your file, and walking into a purchase without pre-approval is the bigger practical risk.
This page covers the inquiry question only. If you want to know what score you actually need to qualify, see what credit score you need for a mortgage instead.
The citable fact: A single mortgage pre-approval, run through one broker or lender, produces one credit check and does not meaningfully damage a borrower’s credit score.
What is the difference between a hard and a soft credit check?
A hard credit check happens when you apply for new credit, such as a mortgage pre-approval, and it is visible to other lenders and can have a small, temporary effect on your score. A soft credit check happens when you or another party review your file without a new application, such as checking your own score, and it never affects your score.
Lenders and brokers use a hard inquiry when you formally apply for financing, because underwriting the request requires your full credit file. A soft inquiry pulls similar underlying data but does not represent a request for new credit, so it carries no weight in scoring models.
| Check type | What triggers it | Visible to other lenders? | Affects your score? | Common example |
|---|---|---|---|---|
| Hard inquiry | Applying for new credit | Yes | Yes, small and temporary | Mortgage pre-approval, car loan application, new credit card application |
| Soft inquiry | Reviewing a file without a new credit application | No | No | Checking your own credit, a lender pre-screening for an offer, a consented background check |
The citable fact: A hard inquiry is triggered by a formal credit application and is visible to other lenders, while a soft inquiry is not and never affects your score.
How much does a hard inquiry actually cost you?
The exact point cost of a single hard inquiry is not published by Equifax Canada, TransUnion Canada, or the scoring models they licence, so no specific number belongs here. What is publicly established is that inquiries carry far less weight than payment history and credit utilisation. A single inquiry’s impact is generally small and fades over time.
Credit scoring formulas are proprietary. Equifax and TransUnion licence scoring models, most commonly FICO-based scores in Canada, and neither the bureaus nor the model providers publish the precise number of points a single hard inquiry costs.
Anyone who states an exact figure, such as a flat five or ten point drop, is estimating rather than quoting a confirmed source. Pekoe will not put an unverified number on this page.
Neither bureau publishes the number of points a single hard inquiry costs, so no point figure appears here. What is published is how inquiries are grouped: Equifax Canada states that multiple inquiries for the same purpose inside a short window are generally counted as one, and that the window ranges from 14 to 45 days depending on the scoring model. That grouping does not apply to credit cards, where each application counts separately.
The citable fact: Neither Equifax Canada nor TransUnion Canada publishes the exact point cost of a hard inquiry, and inquiries carry less weight than payment history or credit utilisation.
Does shopping several lenders for a mortgage mean several hits?
Not if the shopping happens within a short window. Scoring models built for rate shopping recognise that comparing mortgage offers is normal borrower behaviour and group similar mortgage inquiries made close together into a single event. Applying at five banks over several unrelated months is treated differently than comparing five lenders in one focused search.
The logic behind rate-shopping windows is straightforward. A borrower comparing several mortgage lenders in the same week is doing ordinary due diligence, not opening five new lines of credit, so the models built for this de-duplicate the inquiries.
This grouping only applies to inquiries of the same type, mortgage to mortgage. Mixing a mortgage application with a car loan or a credit card application in the same window does not receive the same treatment.

The citable fact: Mortgage-specific credit inquiries made within a short, focused shopping window are generally grouped as one event by scoring models, rather than counted separately.
How does a broker pulling your credit once work?
A mortgage broker typically pulls your credit file once and uses that single file to submit your application to several lenders on your behalf. Applying directly at multiple banks is different, because each bank has no visibility into the others and may run its own hard inquiry. Working with one broker keeps the number of separate inquiries lower.
When you work with a licensed broker, the broker collects your documents, pulls your credit once, and packages that file for the lenders best suited to your situation. Those lenders review the broker’s submission rather than each running a separate credit check.
That is different from a borrower calling five banks individually. Each of those banks runs its own process and, without a rate-shopping window in play, may generate its own hard inquiry.
The citable fact: A licensed mortgage broker usually pulls a borrower’s credit once and submits that file to multiple lenders, rather than generating a separate inquiry at each one.
How long do mortgage inquiries stay on your credit report?
Hard inquiries stay on your credit file for a set period defined by each bureau. An inquiry stays 3 years on an Equifax Canada file and 6 years on a TransUnion Canada file. Its effect on your score typically fades well before it disappears from your file.
Equifax Canada and TransUnion Canada each set their own retention rules for how long a hard inquiry stays visible on a file. These policies are published by the bureaus directly, and figures circulating online are not always current or accurate for the Canadian market specifically.
Rather than repeat an unverified number, the practical point matters more. An inquiry’s weight on your score declines well before the entry itself is removed, so a mortgage inquiry from your pre-approval will not follow you for the life of the loan.
Retention is set by each bureau. A hard inquiry stays 3 years on an Equifax file and 6 years on a TransUnion file. Late or unpaid credit cards and loans, and accounts sent to collections, stay up to 6 years. A bankruptcy stays 6 years after discharge, or 7 years in Newfoundland and Labrador, Ontario, Prince Edward Island and Quebec on a TransUnion file, and 14 years where there has been more than one. A consumer proposal stays 3 years after the debts are paid or 6 years after signing, whichever comes first.
The citable fact: Hard inquiry retention periods are set individually by Equifax Canada and TransUnion Canada, and an inquiry’s effect on your score fades well before the entry is removed.
Does getting declined for a mortgage hurt your credit score?
Being declined does not add a separate negative mark to your credit file. The hard inquiry from the application itself is already recorded regardless of the outcome, but a decline is not reported to the bureaus as its own event. The application result lives with the lender and the broker, not on your credit report.
Your credit file records that an inquiry happened, not whether the application was approved or declined. A lender’s decision is based on the information in your file at the time, including income, debt ratios, and the credit check itself, but the decline is not logged as a new derogatory entry.
A decline is worth understanding rather than repeating with a second application right away. If a lender declines you, ask why, and read what happens if you’re declined after pre-approval before applying elsewhere.
The citable fact: A mortgage decline itself is not reported to the credit bureaus as a separate negative entry, only the original hard inquiry is recorded.
How many mortgage pre-approvals is too many?
There is no fixed number of pre-approvals that crosses a line, but the pattern matters more than the count. One pre-approval refreshed as your search continues, or several mortgage inquiries made close together, reads as normal buyer behaviour. Mixing unrelated credit applications, like a car loan or new credit cards, into the same period is the pattern that raises concern.
A pre-approval typically has a limited shelf life before the rate hold expires and the file needs refreshing. Going back for an updated pre-approval as your home search runs long is routine, not a red flag.
Working with one broker who manages the process, rather than applying independently at several banks over months, keeps your file simpler to read. It also means one person is tracking your file end to end instead of several separate underwriters seeing only a fragment each.
The citable fact: The pattern of credit activity, not a specific count of pre-approvals, is what matters to a lender reviewing your file.
What actually moves your credit score more than an inquiry?
Payment history and credit utilisation carry far more weight in your score than any single inquiry. Missing a payment or running your credit cards close to their limit will move your score more than a mortgage pre-approval ever will. Inquiries sit near the bottom of the factors that determine your score.
Every major scoring model built on the Canadian bureaus weighs several categories of information. Paying every bill on time, every time, and keeping balances low relative to your available credit consistently outweigh a single credit check.
| Factor | Relative impact | Why it matters |
|---|---|---|
| Payment history | HIGH | Missed or late payments are the clearest signal of risk to a lender. |
| Credit utilisation | HIGH | How much of your available credit you are using, lower is generally better. |
| Length of credit history | MEDIUM | A longer track record gives lenders more data to assess. |
| Credit mix | LOW to MEDIUM | Holding a mix of credit types, such as instalment and revolving, shows range. |
| New credit inquiries | LOW | A single hard inquiry has a small, temporary effect. |
Canadian credit scores run from 300 to 900. Equifax Canada and TransUnion Canada both report inside that range. Neither bureau publishes the percentage weighting it gives each scoring factor, and the Financial Consumer Agency of Canada states plainly that bureaus and lenders use different formulas and do not share the exact details, so no weighting is stated on this page.
The citable fact: Payment history and credit utilisation have a far greater and longer-lasting effect on your credit score than a mortgage inquiry.
Should you avoid other credit applications while buying a home?
Avoid opening new credit, such as a car loan, a new credit card, or furniture financing, between your pre-approval and your closing date. A new account changes your debt ratios and can affect the mortgage a lender is willing to approve, separate from any credit score impact. Talk to your broker before applying for anything else while your mortgage file is active.
Lenders re-verify your credit and your debt load close to closing, not only at pre-approval. A new car payment or a large furniture purchase on credit adds to your monthly obligations and can push your debt service ratios past what the lender approved.
This is a bigger practical risk than any credit score movement from a mortgage inquiry. It can change the mortgage amount you qualify for, or the approval itself, between pre-approval and closing.
The citable fact: New credit applications during a mortgage purchase are riskier because of the debt they add to your file, not because of any score impact from the inquiry itself.

Frequently asked questions
Does a mortgage pre-approval show up on my credit report?
Yes. A pre-approval usually generates a hard inquiry that appears on your credit file, visible to future lenders who pull your report. It sits alongside your other inquiries, and its effect on your score fades well before the entry itself is removed.
Will checking my own credit score hurt it?
No. Checking your own score or report is a soft inquiry, and soft inquiries never affect your score or appear to other lenders. Check your own credit as often as you want before applying for a mortgage.
Does my broker check my credit once or multiple times during pre-approval?
A broker typically pulls your credit once at the start of the pre-approval process and uses that single file when submitting your application to lenders. If your pre-approval expires and needs refreshing months later, a new check may be required at that point.
Do all banks pull credit separately if I apply directly to each one?
If you apply directly to several banks outside a broker relationship and outside a recognised rate-shopping window, each bank may run its own hard inquiry because it cannot see what the others have already checked. Working through one broker, or shopping within a focused window, keeps this from stacking up.
Is a mortgage pre-approval a hard inquiry or a soft inquiry?
A mortgage pre-approval is typically a hard inquiry, because you are formally applying for financing. Some lenders offer a soft-check pre-qualification step first, but a full pre-approval usually involves a hard pull.
Does getting pre-approved guarantee I will get the mortgage?
No. A pre-approval is based on the information available at the time and is not a final approval, and final approval still depends on the property, an updated file, and lender sign-off at the time of purchase. Read more on what happens if you’re declined after pre-approval.
How many mortgage pre-approvals can I get without it adding up on my file?
Mortgage-specific inquiries made within a short shopping window are generally grouped as one event by scoring models, so comparing several lenders in a focused search is normal. Equifax Canada puts that window at 14 to 45 days depending on the scoring model, so keep your shopping close together rather than spread across many months.
Does a mortgage inquiry affect my ability to get other credit at the same time?
A single mortgage inquiry carries limited weight and is unlikely on its own to affect approval for other credit. What affects other applications more is the new debt a mortgage adds to your file once it closes, since that changes your overall debt load.
Should I get pre-approved before I’ve decided to buy?
Getting pre-approved early tells you what you can afford and where you stand, and one inquiry from that step is not a reason to delay. If your search runs long and the pre-approval expires, expect to refresh it, which may involve another check.
Does refreshing an expired pre-approval count as a new inquiry?
It can, depending on how much time has passed and the specific lender’s process. Ask your broker whether a refresh requires a new credit pull before you request one.
Is the chat on this page an AI bot?
No. Pekoe’s chat connects you to a licensed member of the team during business hours, and to a direct reply from a licensed broker outside those hours. There is no AI persona standing in for an advisor.
What credit score do I need for a mortgage pre-approval?
That depends on the lender and the type of mortgage, and it is covered in full on what credit score you need for a mortgage. This page focuses only on how the inquiry itself affects your score, not the minimum score required.
Does being declined after pre-approval mean something is wrong with my credit?
Not necessarily. Declines can relate to income, debt ratios, the property itself, or documentation, not only credit history. See what happens if you’re declined after pre-approval for the common reasons.
How long does the mortgage pre-approval process take?
Timelines vary by lender and by how complete your documents are when you apply. See how long a mortgage takes for a full breakdown of the process.
