You checked your credit score and it dropped — maybe 20 points, maybe 80. Don’t panic. A score drop is almost always diagnosable, and most causes are fixable with a clear plan. This guide walks through every common reason a Canadian credit score falls, how much it likely hurt, and exactly what to do about it.
Step One: Find Out What Actually Changed
Before guessing, check your credit report. Both Equifax Canada and TransUnion Canada are required by law to provide your full report for free. You can also use Borrowell (Equifax-based) or Credit Karma Canada (TransUnion-based) for free ongoing monitoring with email alerts when your score changes.
When reviewing your report, look specifically for: any new accounts or hard inquiries you don’t recognize, changes in balances on existing accounts, any accounts newly marked as late or in collections, closed accounts that recently disappeared, and errors — incorrect payment dates, wrong balances, or accounts that don’t belong to you.
Once you know what changed, match it to the causes below. Most drops trace back to one of these seven.
The 7 Most Common Reasons Your Score Dropped
1. You Missed a Payment — or Paid Late
This is the single most damaging cause on this list. Payment history is 35% of your credit score — the biggest single factor. Even one payment that’s 30 or more days late can drop a score by 40–110 points, and the damage is proportionally larger if you started with a higher score. A single late payment on an 800 score hurts far more than the same event on a 600 score.
Key Takeaway
A single 30-day late payment can drop a credit score by 40–110 points — and the higher your score, the harder the fall. Set up autopay for at least the minimum on every account. This one habit prevents the most common and most damaging credit event.
What to do: Bring the account current immediately. Set up autopay for at least the minimum payment on every account. If this was a genuine one-time mistake, call the lender and ask for a “goodwill adjustment” — some lenders will remove a first-time late payment from your report if your overall history is strong.
Recovery timeline: Score impact softens meaningfully at the 12–18 month mark. Full recovery takes 2–4 years, at which point the record is still on your report but carries minimal weight.
2. Your Credit Utilization Jumped
Credit utilization — the percentage of your available credit you’re using — accounts for 30% of your score. If your balance rose from $200 to $800 on a $1,000-limit card, your utilization went from 20% to 80%. Above 50% starts to hurt significantly; above 80% can drop a good score by 30–50 points.
Key Takeaway
Utilization is the fastest credit score lever available. Pay down your balance before the statement closing date — not just the payment due date — and your score will reflect it within 30–45 days. Fix this month, score improves next month.
What to do: Pay down balances before your statement closing date — not just the payment due date. The closing date is when the lender reports your balance to the bureau, so that’s the number that counts. Alternatively, request a credit limit increase (if you won’t use it) — same balance with a higher limit produces lower utilization.
Recovery timeline: This is the fastest fix available. Reduce the balance, and your score typically reflects it within 30–45 days once the next statement reports.
3. You Applied for New Credit (Hard Inquiry)
Every formal credit application — credit card, car loan, mortgage, line of credit — triggers a hard inquiry. Each hard inquiry typically drops your score by 5–10 points, and multiple inquiries in a short period signal financial stress to scoring models.
What to do: Avoid applying for credit you don’t need. If you’re shopping for the best mortgage or auto loan rate, note that Canadian scoring models typically group multiple inquiries for the same loan type within 14–45 days as a single inquiry — so rate-shopping efficiently doesn’t multiply the damage. Soft inquiries (checking your own score, prequalification checks) have zero impact.
Recovery timeline: Hard inquiry impact fades steadily over 12 months and is removed from score calculations entirely after 2 years.
4. You Closed an Old Credit Card
Closing a credit card hurts your score in two ways simultaneously: it reduces your total available credit (increasing utilization across all accounts), and if it was one of your older accounts, it shortens your average credit history length. Both factors move in the wrong direction — it feels like responsible behaviour, but it typically isn’t.
What to do: Reconsider closing old cards, especially cards with no annual fee. A dormant card with a $0 balance still contributes to your total available credit and history length. If the card has an annual fee, call and ask for a downgrade to a no-fee version rather than closing it. If you’ve already closed it, focus on keeping remaining accounts in good standing and wait for other accounts to age.
Recovery timeline: The utilization impact resolves as you pay down other accounts. The history length impact takes 2+ years to recover.
5. An Account Went to Collections
If a debt — a forgotten phone bill, unpaid medical expense, old credit card — gets sent to a collection agency, it appears as a separate negative item. This is one of the most damaging events possible: a collection can drop a score by 80–150 points depending on the balance, the age of the debt, and your starting score.
What to do: Don’t ignore collection calls — verify the debt is yours first (ask for written validation). In most Canadian provinces, a debt becomes statute-barred after 2 years, meaning the collector can’t sue you for it. Paying a collection doesn’t automatically remove it from your report, but “settled” vs. “outstanding” matters to some lenders. If you’re going to pay, request a “pay for delete” agreement in writing before paying.
Recovery timeline: The collection item stays on your Canadian report for 6–7 years from the original delinquency. Score begins recovering within 12–24 months if all other accounts remain in good standing.
6. There’s an Error on Your Credit Report
Credit report errors are more common than most people realize. Common errors include: accounts that don’t belong to you (especially after identity theft or mixed files), incorrect late payment dates, balances that were paid but still show as owing, duplicate accounts, and outdated negative items that should have aged off.
What to do: Pull your full report from both Equifax Canada (equifax.ca) and TransUnion Canada (transunion.ca). File a written dispute with each bureau where you find an error — include documentation (bank statements, receipts, settlement letters) where possible. Both bureaus are required to investigate disputes within 30 days and correct confirmed errors.
Recovery timeline: The fastest fix available if the error is confirmed — 30–45 days from a successful dispute to score update.
7. A Major Life Event or Account Change
Some score drops are side effects of normal financial moves: co-signing a loan for someone else (their behaviour now affects your score), taking out a new mortgage (new inquiry + new debt), going through a divorce where you become responsible for shared debts, or a student loan entering repayment status.
What to do: Understand whether the drop is temporary (new mortgage inquiry and initial balance — these recover as the account ages and you make payments) or potentially ongoing (co-signed debt where the other person may miss payments). For divorce: close or separate joint accounts as part of the legal process before finalizing.
Recovery timeline: New mortgage/car loan: recovers in 6–12 months. Co-signing risk: ongoing. Life event-related missed payments: follows the missed payment timeline above.
Recovery Timeline at a Glance
| Cause | Typical Score Drop | When Score Starts Recovering | Full Recovery |
|---|---|---|---|
| Missed payment (30+ days late) | 40–110 pts | 12–18 months (with on-time payments) | 2–4 years |
| High credit utilization | 10–50 pts | Next statement cycle (~30–45 days) | Immediate once balance paid down |
| Hard inquiry (new application) | 5–10 pts | Fades over 12 months | 2 years (removed from scoring) |
| Closed old credit card | 10–30 pts | 6–12 months | 2+ years |
| Collection account | 80–150 pts | 12–24 months | 6–7 years (item ages off report) |
| Credit report error | Varies | 30–45 days after successful dispute | Within 45 days |
| New mortgage or major loan | 10–30 pts | 6–12 months | 12–18 months |
Key Takeaway
High utilization is the only cause in this table with a recovery time under 60 days. If your score dropped and you’re carrying a high balance, paying it down before your next statement close is the single fastest move available.
What Not to Do After a Score Drop
These common reactions often make things worse:
- Don’t apply for more credit to “fix” it — more hard inquiries make the situation worse, not better
- Don’t close your remaining credit cards — this increases utilization and shortens history length
- Don’t pay a “credit repair” company — everything a credit repair company can do (disputes, goodwill letters), you can do yourself for free. Canada’s Financial Consumer Agency has warned about credit repair scams
- Don’t ignore collection calls without first verifying the debt in writing — ignoring doesn’t make it go away
- Don’t carry a balance to “show you use it” — carrying a balance doesn’t help your score and costs you interest
Bridging the Gap While Your Score Recovers
Credit rebuilding takes months to years. One of the biggest practical risks is running short on cash between paycheques and missing the credit card payment that matters — setting your recovery back 12–18 months.
If you’re managing a tight cash flow while rebuilding, a cash advance app like NotchUp can cover a gap between paycheques without a credit check and without affecting your credit file. It won’t improve your score — but it can prevent the missed payment that would worsen it. NotchUp charges a $5 flat fee, sends via Interac e-Transfer in about 15 minutes, and does not report to the credit bureaus (with the exception of NotchUp Plus).
The credit-rebuilding work itself requires time and consistent on-time payments — see our guide to building credit in Canada for the full strategy, and realistic timelines for each starting point.
Frequently Asked Questions
How much does a missed payment affect a credit score in Canada?
A single 30-day late payment can drop your score by 40–110 points, depending on your starting score. Higher scores experience proportionally larger drops — a single late payment on a 780 score hurts more than on a 620 score.
Why did my credit score drop when I paid off a loan?
Paying off an installment loan (car loan, personal loan, student loan) closes that account, which can cause a small, temporary drop: it reduces your credit mix and stops the ongoing positive payment history from that account. The drop is usually minor (5–15 points) and typically recovers within 3–6 months.
How long does it take to recover from a credit score drop in Canada?
It depends on the cause. High utilization fixes in 30–45 days once balances are paid down. Hard inquiry impact fades over 12 months. A missed payment’s impact softens after 12–18 months of on-time payments. Collections take 2–4 years to reduce impact significantly. See the recovery timeline table above for specifics.
Does a hard inquiry always lower your credit score?
Each hard inquiry typically drops a score by 5–10 points. Multiple inquiries within 14–45 days for the same loan type (mortgage, auto) are typically treated as a single inquiry by Canadian scoring models. Soft inquiries — checking your own score, prequalification checks — never affect your score.
Can I dispute errors on my Canadian credit report?
Yes. Both Equifax Canada and TransUnion Canada have free online dispute processes. File your dispute, provide documentation, and both bureaus are required to investigate within 30 days. If the error is confirmed, it must be corrected. Dispute directly at equifax.ca or transunion.ca.
