Ratesopedia’s Take
Credit score drops rarely happen randomly. Most changes trace back to five key factors: payment history, credit utilization, new credit applications, account closures, or reporting errors. The good news? Most drops are temporary and reversible with strategic action. This guide breaks down the most common causes affecting Canadians in 2026 and shows you how to recover quickly.
How Credit Scores Work in Canada
Canadian credit scores range from 300 to 900, with Equifax and TransUnion as the two main credit bureaus. Your score reflects how you manage credit over time, not your income or savings.
Five factors determine your score, each carrying different weight. Understanding this breakdown helps you identify why your score might have changed.
| Factor | Weight | What It Measures |
|---|---|---|
| Payment History | 35% | On-time vs late payments |
| Credit Utilization | 30% | Balance vs available credit |
| Length of History | 15% | Age of oldest and average accounts |
| Credit Mix | 10% | Variety of credit types |
| New Credit | 10% | Recent applications and inquiries |
Your score can vary between Equifax and TransUnion by 20-30 points under normal circumstances. Lenders report information at different times throughout the month, creating natural fluctuations.
Payment History Issues
Payment history accounts for 35% of your credit score, making it the single most damaging factor when problems occur. Even one late payment can significantly impact your score.
Late Payment Impact
Credit card issuers and lenders typically don’t report late payments to credit bureaus until they reach 30 days past due. If you pay on day 29, you might face a late fee, but your credit score remains unaffected.
Once a payment crosses the 30-day threshold, the damage shows up on your credit report. According to recent data, a payment reported as 30 days late can cause a fair credit score to fall by 17 to 37 points. An excellent score could drop by 63 to 83 points.
| Late Payment | Fair Score Impact | Excellent Score Impact | Report Duration |
|---|---|---|---|
| 30 days | 17-37 points | 63-83 points | Up to 6 years |
| 60 days | 40-60 points | 80-100 points | Up to 6 years |
| 90+ days | 50-80 points | 113-133 points | Up to 6 years |
The severity increases with payment delinquency. A 90-day late payment hits much harder than a 30-day mark, with excellent scores potentially dropping over 100 points.
Forgotten Accounts
Many Canadians discover credit score drops caused by old accounts they no longer use. A store credit card opened years ago for a one-time discount might post an annual fee you never see.
These forgotten accounts continue reporting to credit bureaus. Missing payments on them damages your score just as severely as missing payments on active accounts you use regularly.
Credit Utilization Changes
Credit utilization measures the percentage of available credit you’re currently using. This factor comprises 30% of your credit score, making it the second-largest influence after payment history.
The 30% Threshold
Credit scoring models calculate utilization both per card and across all revolving accounts combined. Exceeding 30% utilization triggers score declines, with maxed-out cards causing drops of 50 points or more even when you pay on time.
Rates and terms may vary by financial institution. For optimal credit health, aim to keep utilization below 30%, with under 10% being ideal for the highest scores.
- Per-Card Utilization: Each individual card’s balance divided by its limit affects your score separately
- Overall Utilization: Your total balances across all cards divided by total available credit
- Statement Timing: Credit card companies report your balance on the statement closing date, not the payment due date
Common Utilization Mistakes
You could charge $4,500 to a $5,000 limit card, have that 90% utilization reported to bureaus, then pay it off in full before the due date to avoid interest. Your score still drops because bureaus saw the high utilization.
Strategic timing matters. If you plan to make a large purchase, consider paying down your balance before your statement closes or splitting the purchase across multiple cards to maintain lower per-card utilization.
Credit Limit Reductions
Credit card issuers periodically review accounts and can decrease credit limits without advance notice. When your limit drops but your balance remains the same, your utilization ratio automatically increases.
This creates a challenging situation where your score falls even though your spending behaviour didn’t change. If you carry a $2,500 balance on a $10,000 credit card at 25% utilization, and the issuer reduces your limit to $5,000, your utilization suddenly jumps to 50%.
Issuers typically reduce limits when they detect increased risk in your credit profile, such as making minimum payments for several months instead of paying in full, or showing signs of financial stress on other accounts.
New Credit Applications
Every time you apply for a credit card, auto loan, personal loan, or mortgage, the lender pulls your credit report, creating a hard inquiry. Each hard inquiry can lower your score by 5 to 10 points.
While a single inquiry rarely causes a major drop by itself, multiple applications within a short period signal to lenders that you might be financially stretched. Applying for three credit cards, an auto loan, and a personal loan within a month could generate five or more hard inquiries.
Rate Shopping Exception
Credit scoring models treat multiple mortgage or auto loan inquiries within a 45-day window as a single inquiry. This rate-shopping window lets you compare lenders without each application compounding the damage.
Credit card applications don’t receive this treatment. Each card application counts as a separate inquiry regardless of timing, making it important to be selective about which cards you apply for.
- Hard Inquiry Duration: Remains on your credit report for three years at Equifax and six years at TransUnion, but only affects your score for the first 12 months
- Impact Fades: An inquiry might cost 8 points initially, 5 points after six months, 2 points after nine months, and zero points after a year
- Soft Inquiries: Promotional inquiries for preapproved offers and employment credit checks don’t affect your score
Account Closures
Closing an old account or having one closed by the issuer can trigger significant score drops. The age of your credit accounts comprises 15% of your score, affecting both your oldest account and the average age of all accounts.
Why Closing Accounts Hurts
When you close a 10-year-old credit card that represents your oldest account, your credit history suddenly looks much younger. If your other accounts average three years old, losing that decade-old account dramatically reduces your average account age.
Additionally, closing an account reduces your total available credit, increasing your credit utilization ratio even if your spending stays constant. This creates a double impact on your score.
Paying Off Loans
Finishing student loan or auto loan payments can temporarily drop your score, even though it’s a positive financial milestone. The reason relates to credit mix, as scoring models favour seeing you manage different types of credit.
When you pay off your only installment loan and only have credit cards remaining, you’ve reduced the variety in your credit profile. The scoring model reflects this change, though the drop is usually modest and temporary.
Credit Report Errors
Credit reporting errors are surprisingly common and can devastate your score through no fault of your own. Approximately 20% of consumers have errors on at least one of their credit reports.
- Incorrect Late Payments: Payments marked late when you paid on time
- Wrong Account Status: Accounts listed as open when you closed them years ago
- Incorrect Credit Limits: Lower limits shown than actual amounts, inflating utilization
- Duplicate Accounts: One loan reported twice, making it appear you owe double
- Mixed Files: Accounts belonging to someone else with a similar name appearing on your report
Sometimes creditors report accurate information to the wrong credit bureau, creating discrepancies between your Equifax and TransUnion reports. You might have a perfect payment record according to one bureau but show delinquencies on the other.
2026 Credit Scoring Changes
Canadian lenders increasingly use trended data alongside the traditional score, examining not just your current balances but your payment patterns over time.
In practice, a borrower who only makes minimum payments can look riskier under trended data than the score alone suggests, even if income and debt levels have not changed.
Rising delinquency rates on credit cards, auto loans, and personal loans have contributed to declining average scores. Economic pressures from inflation and elevated interest rates continue to affect Canadian consumers in 2026.
How to Recover Your Score
Most credit score drops are temporary and reversible with consistent action. The recovery timeline depends on what caused the decline and how quickly you address it.
Immediate Actions
- Check Your Credit Report: Review reports from both Equifax and TransUnion to identify the specific cause
- Dispute Errors: File disputes immediately if you find inaccuracies, providing supporting documentation
- Pay Down Balances: Focus on cards closest to their limits first to reduce utilization quickly
- Set Up Autopay: Prevent future late payments by automating at least minimum payments
- Request Limit Increases: Ask issuers to raise your credit limits without hard inquiries to improve utilization ratios
Recovery Timeline
High utilization often rebounds within one to two months once balances drop below 30%. Hard inquiries cause short-term dips that typically recover within a few months as the inquiry ages.
Missed or late payments affect your score for months or years, though the impact fades over time. The negative mark remains on your report for six years, but its influence diminishes as you build positive payment history.
Prevention Strategies
Preventing credit score drops requires ongoing monitoring and strategic credit management. Small habits can protect your score from unexpected declines.
- Monitor Regularly: Check your credit score monthly through your bank’s app or free monitoring services
- Pay Before Statement Dates: Make payments before your statement closes to ensure lower balances get reported
- Keep Old Accounts Active: Use old credit cards occasionally to prevent issuer closures due to inactivity
- Limit New Applications: Apply for new credit only when necessary and space out applications over time
- Review All Accounts: Audit your credit accounts annually to identify any you’ve forgotten about
Before making major financial decisions, compare savings accounts and other products to ensure you’re maximizing value while maintaining healthy credit.
Bottom Line
Credit score drops rarely happen without cause. Most changes trace back to payment history issues, credit utilization spikes, new credit applications, account closures, or reporting errors. Understanding which factor affected your score helps you take targeted action to recover.
The majority of score drops are temporary and reversible. Paying on time, keeping utilization below 30%, and monitoring your credit reports can prevent most issues. When drops do occur, addressing the root cause quickly minimizes long-term impact.

why did my credit score drop – FAQ
What are the most common reasons credit scores drop in Canada?
The most common reasons include late or missed payments (35% of your score), high credit utilization above 30% (30% of your score), new credit applications creating hard inquiries, closing old accounts that reduce credit history length, and errors on your credit report. Payment history issues cause the most severe drops.
How much does a missed payment drop your credit score in Canada?
A payment reported as 30 days late can drop a fair credit score by 17 to 37 points and an excellent score by 63 to 83 points. A 90-day late payment can drop an excellent score by 113 to 133 points. The impact depends on your starting score and previous payment history.
What credit utilization ratio should I maintain?
Keep your credit utilization below 30% on each card and across all cards combined. For optimal scores, aim for under 10% utilization. Credit card companies report your balance on the statement closing date, so pay down balances before this date to ensure lower utilization gets reported.
How many points does a hard inquiry drop your credit score?
A single hard inquiry typically drops your score by 5 to 10 points. The impact is temporary, usually recovering within a few months. Multiple mortgage or auto loan inquiries within 45 days count as one inquiry, but each credit card application counts separately regardless of timing.
Why did my score drop after paying off a loan?
Paying off an installment loan can temporarily drop your score because it reduces your credit mix. Scoring models favour seeing you manage different types of credit, both revolving accounts like credit cards and installment loans like auto loans or mortgages. The drop is usually modest and temporary.
How long does it take for a credit score to recover?
Recovery time depends on the cause. High utilization often rebounds in one to two months once balances drop. Hard inquiries recover within a few months. Late payments affect your score for months or years, though the impact fades over time. The negative mark stays on your report for six years but has less influence as you build positive history.
Can closing a credit card hurt my credit score?
Yes, closing a credit card can hurt your score in two ways. It reduces your total available credit, which increases your utilization ratio even if spending stays the same. It also affects the average age of your accounts, especially if you close your oldest card. Keep old accounts active with occasional small purchases instead.
How do I dispute errors on my credit report?
Contact both Equifax and TransUnion directly to file a dispute. Provide supporting documentation such as payment receipts, account statements, or correspondence with creditors. The bureau must investigate within 30 days and correct any confirmed errors. Check your report again after the investigation to ensure corrections were made.
What credit score changes happened in Canada in 2026?
Canadian lenders increasingly combine the traditional score with trended data, which looks at payment patterns over time rather than just current balances. A borrower who consistently pays only the minimum can therefore be assessed as riskier than the score alone suggests, even with unchanged income and debt levels. The mortgage stress test is a separate income-based rule and is not driven by your score.
Should I worry about small credit score fluctuations?
Small fluctuations of 5 to 10 points are normal and occur as lenders report information at different times throughout the month. Your score can vary by 20 to 30 points between Equifax and TransUnion under normal circumstances. Investigate drops of 20 points or more to identify specific causes and address them if needed.
Can I raise my credit score back up in 30 days?
A meaningful jump in 30 days is possible only if the drop came from high utilization, since paying down balances before your statement closes can restore several dozen points within one billing cycle. Recovery from a late payment or a closed account takes longer, usually several months to a year, because those marks stay on your report and lose influence gradually. Dispute any reporting error right away, since bureaus must investigate within 30 days and a correction can restore your score quickly. For a step-by-step recovery plan, see our guide to increase your credit score.
Why does my score drop if I pay my card in full?
Because the balance sent to the credit bureaus can be close to your limit, even if you pay it off in full afterwards. According to the Financial Consumer Agency of Canada (FCAC), being close to your credit limit is one of the factors that affect your score, and the bureaus update your credit report at least once a month. For example, with a $500 limit, a $450 balance already uses 90% of your available credit. To bring that ratio down, make a payment before your statement date, or ask for a limit increase once your issuer allows it.
