Why Did My Credit Score Drop?
Reporting periods below were verified on 19 August 2026 against Canadian credit bureau guidance.
You opened the app, the number was lower than last month, and nothing obvious happened. No missed payment you can remember. No new loan.
Something did change — scores do not move on their own. The useful question is which of about nine things it was, because some of them fix themselves in a month and one or two of them are telling you about a real problem.
The most common cause of a sudden drop with no obvious trigger is a jump in credit utilisation — your reported balances rose relative to your limits, often just because a statement landed before your payment did. That one can reverse within a single billing cycle. The causes that stay are a payment reported 30 or more days late, an account sent to collections, or a new derogatory entry. Everything else is usually noise.
Where to go from here. Most people reading this have a temporary, self-correcting dip — the nine causes below will tell you which. If the drop traces to balances you cannot pay down, or to accounts already in collections, there is a separate section near the end for homeowners, because equity changes what is possible there. If you rent, skip it; the diagnosis is the same and the fix is behavioural.
The nine things that actually move a Canadian credit score
Ordered roughly by how often they are the answer.
| Cause | How it shows up | How long it lasts |
|---|---|---|
| 1. Utilisation jumped | Balances rose against limits. Often just statement timing | Reverses as balances fall — often one cycle |
| 2. A payment went 30+ days late | Creditors generally do not report until you are a full cycle behind | Up to 6 years from when it was reported |
| 3. A credit limit was cut | Same balance, smaller limit — utilisation rises with no spending | Until the balance or the limit changes |
| 4. You closed a card | Removes available limit and, eventually, account history | Utilisation effect immediate; history effect much longer |
| 5. A hard inquiry | You applied for something. Small effect, but real | Stays on the report 3 years; scoring weight typically fades within about a year |
| 6. An account went to collections | Often a forgotten telecom or utility bill, not a loan | 6 years from the first delinquency, paid or not |
| 7. A new account opened | Lowers the average age of your accounts | Recovers as the account ages — usually a few months |
| 8. A loan was paid off | Yes, really — closing an instalment loan can nudge a score down | Temporary — typically settles within a cycle or two, and not a reason to keep debt |
| 9. An error or fraud | An account that is not yours, or a payment marked late in error | Until you dispute it — do this first if nothing else fits |
Start with utilisation, because it is usually the answer
Utilisation is the share of your available revolving credit you are using. It is recalculated every time a lender reports, which is typically monthly, and it carries real weight in every scoring model.
The trap is that lenders report your statement balance, not what you owe today. Pay your card in full on the 20th, but if the statement closed on the 15th showing $4,200, that is the number that gets reported. You can carry no debt at all and still look heavily used on paper.
Common ways this happens without you doing anything wrong:
- A large purchase landed just before the statement date, even though you paid it off straight after.
- A lender reduced your limit. Same balance, higher percentage.
- You closed a card you never used. The balances stayed; the available limit shrank.
- You moved a balance between cards, and both got reported mid-transfer.
General guidance in Canada is to keep reported utilisation under 30%, and lower tends to be better. You do not need to carry a balance or pay interest to show well — that is a persistent myth. Using the card and paying it off is enough.
Work out where you actually sit, and what paying a specific amount down would do, with the credit utilization calculator. Its what-if simulator is the quickest way to see whether utilisation is your problem or a red herring.
Why did my credit score drop after paying off debt?
This is the one that feels most unfair, and it has two separate explanations depending on what you paid off.
If you paid off and closed an instalment loan — a car loan, a personal loan — you removed an active account with a payment history attached. That changes the mix of account types on your file and lowers the average age of what remains. The dip is usually small and typically settles within a cycle or two. It is not a reason to keep paying interest on something you could clear.
If you paid off a credit card and the score still fell, check the timing rather than the payment. Your lender reports the statement balance, so a payment made after the statement closed will not show until the next cycle. And if you closed the card afterwards, you removed its limit from your utilisation calculation entirely — which can push your reported usage up on the balances that remain.
My score dropped for no reason I can see
A small drop with no visible cause is common and is usually reporting timing rather than anything you did. Lenders report on their own schedules, not on the same day, so your file can look different from one week to the next purely because of when balances were captured.
The test is whether it recovers. A timing artefact reverses at the next reporting cycle. A real change — a late payment, a collection, a limit reduction — does not, and it will be visible as a new or altered entry when you pull your actual report. If the number keeps sliding month after month, stop looking for a single event and read the section on symptoms further down.
If it was a missed payment, know what happens next
Most creditors do not report a payment as late until you are a full billing cycle behind — around 30 days. A few days late is usually a fee, not a credit event. That is why a drop can arrive weeks after the thing that caused it.
Once it is reported, it stays for up to six years, and paying the balance afterwards does not remove it. What paying does is stop it getting worse, and let it age. Payment history carries more weight than almost anything else in a scoring model, so the priority is making sure there is not a second one.
If a payment is late because the money genuinely is not there — not because of an oversight — treat that as the actual problem. One late payment is a scoring event. A pattern is a cash-flow problem, and cash-flow problems do not resolve by being ignored.
Two things worth ruling out before you worry
Why is my TransUnion score different from my Equifax score?
Because they are not measuring the same thing from the same data. The two bureaus hold separate files, and not every lender reports to both — so an account, a balance or a late payment can appear on one and not the other.
On top of that, the score you see in a free app is usually an educational scoring model, which is not the model a lender uses when it pulls your file. Different model, different data, different number. A gap between two sources is normal and is not evidence that something is wrong.
The practical rule: track one source against itself over time. A drop within a single source means something. A difference between two sources usually does not.
Check whether the entry is even yours
If none of the nine causes fits, pull your actual credit report — not an app score — from both bureaus and read the account list line by line. An account you do not recognise, or a payment marked late that you know you made, is a dispute, and filing one is free.
Both bureaus take disputes online: Equifax Canada’s dispute page and TransUnion Canada’s dispute page. Investigations are generally concluded within about 30 days, and if the information cannot be verified it is removed or corrected. Do this before anything else, because every other step assumes the data is right.
When the drop is a symptom rather than the problem
Everything above is maintenance. But some drops are the credit file catching up with something real: balances climbing month after month because income no longer covers the outgoings, or an account that has already been handed to a collection agency.
You can tell the difference quickly. A one-off dip has a single identifiable cause and reverses. A symptom looks like a downward line over several months, with utilisation rising because you are paying minimums, and no month where the balance actually falls.
If that is the shape of it, no amount of credit-file management fixes it. The score is reporting the debt accurately. The debt is what has to change.
For homeowners: the option most people are not offered
This section is only relevant if you own property with usable equity. If you rent, the honest answer is that the route out is a repayment plan, a credit counselling arrangement, or a conversation with a Licensed Insolvency Trustee — and there is no shortcut worth pretending otherwise.
If you do own a home, high-interest revolving balances can often be paid out of equity. The cards go to zero, the reported utilisation drops sharply at the next reporting cycle, and the accounts report as current instead of maxed. Over time, balances that are paid down and payments that are made on time do tend to help — but be clear about what it does and does not do:
- It does not erase your history. Missed payments already reported stay for their six years. Collections already on file stay six years from first delinquency whether you pay them or not. Nothing wipes the file clean, and anyone who tells you otherwise is selling something.
- It moves the debt onto your house. An unsecured card balance is not registered against your home. A second mortgage is. If the payment is not made, the lender’s remedy runs against the property. That is the trade, and it is not a small one.
- It needs an exit. An interest-only second mortgage is bridge money, not a destination. Before it makes sense there should be a plan — refinancing both into one mortgage at your next renewal once the file has recovered, paying the principal down deliberately, or a dated income event. “We will refinance in two years” is a hope, not a plan, unless there is something behind it.
Where the numbers do work, it tends to be a second mortgage behind your existing first, or a full refinance if the file supports it. See debt consolidation using home equity for how that is structured, and mortgages with bad credit if your score has already slipped far enough to worry you.
Alternative and private lenders tend to place more weight on the property and the available equity than a bank would, while still considering income, credit history, location and how the loan gets repaid. Most home-equity lending is limited to roughly 80% of appraised value, though lender and product rules vary — so if the mortgage plus the debt pushes past what the property realistically supports, there is nothing to arrange, and we will tell you that rather than string it out.

If the balances are the problem, find out what your equity can do
Send your address, your mortgage balance and your total card and line-of-credit balances. We will tell you whether paying them out of equity works, what it would cost each month, and if it does not work we will say so and point you to the right option instead.
A conversation, not an application — we will tell you what the numbers look like before anything is submitted anywhere.
Credit score drop FAQ
Why did my credit score drop when I did nothing wrong?
Usually reported utilisation. Lenders report your statement balance rather than your current balance, so a purchase made just before the statement date can push your reported usage up even if you paid it off days later. A reduced credit limit or a closed card does the same thing without any spending at all.
Why did my score drop after I paid off a loan?
Closing an instalment loan removes an active account with a payment history from the mix, and can lower the average age of your accounts. The effect is usually small and temporary. It is not a reason to keep debt you can afford to clear.
How long does a late payment stay on my credit report in Canada?
Up to six years from when it was reported, and paying the past-due balance afterwards does not remove it. What it does is stop the situation deteriorating and let the entry age.
How long does a collection stay on my credit report?
Six years from the date of first delinquency on the account, whether or not you pay it. Paying it does not remove it early, though a collection showing a zero balance may weigh differently than an outstanding one.
Does checking my own credit score lower it?
No. Checking your own report or score is a soft inquiry and does not affect it. Hard inquiries — where a lender pulls your file because you applied for something — are the ones that count, and they stay on the report for three years, though their scoring weight fades much sooner.
Should I close credit cards I do not use?
Not usually, if the card is free to hold. Closing it removes available limit, which raises your reported utilisation on the balances that remain, and eventually removes that account’s history. If it carries an annual fee, the maths is different — but expect a dip.
My score is different on two apps. Which one is right?
Both, probably. Different sources use different scoring models, and the two bureaus do not hold identical data, so the numbers are not meant to match. Track one source over time rather than comparing across them.
Will paying off my credit cards raise my score quickly?
Reported utilisation updates when your lenders next report, usually within a cycle, so that part can move relatively quickly. Missed payments and collections already on your file do not move — they age off on their own timetable. So expect improvement, not a reset.
How long will it take to rebuild after this?
It depends on which of the nine causes it was — a utilisation dip and a collection are completely different timescales. We have set out both clocks in how long it takes to rebuild credit after debt in Canada.
