The standard advice — “never close old credit cards” — is too blunt. It is right in most cases, but it ignores the legitimate reasons to close a card and overstates how damaging closure always is. The truth is that whether to close an old credit card depends on three things: whether the card carries an annual fee you cannot justify, how the closure will affect your utilization ratio, and whether the card is your oldest account. This article is part of the Canadian credit scores hub.
Closing a credit card can hurt your score through two mechanisms. First, it removes available credit, which raises your utilization ratio — the percentage of your total credit limit you are currently using. Second, if the closed card is your oldest account, it shortens your average account age. Both factors are weighted in Canadian credit scoring models. But the damage from each depends heavily on your overall credit profile, and for many people with strong credit and multiple accounts, closing one card has a modest and temporary effect.
For cards with no annual fee, the calculation is simple: keep them open. They cost nothing and provide a passive benefit to your utilization ratio and account history. For cards charging $100–$150 per year whose benefits you do not use, keeping the card open has a real cost — and the credit score benefit rarely justifies it. The right question is not “will this hurt my score?” but “by how much, and is that worth the annual fee I am avoiding?”
What Closing a Card Does to Your Credit Score
Credit scores in Canada (Equifax and TransUnion) are calculated from five factors. Closing a card directly affects two of them.
| Credit Factor | Approximate Weight | How Closing a Card Affects It |
|---|---|---|
| Payment history | ~35% | No impact if closed with $0 balance |
| Credit utilization | ~30% | Increases utilization — negative effect |
| Credit history length | ~15% | May decrease if it is your oldest card |
| Credit mix | ~10% | Minor impact if only revolving account closed |
| New credit inquiries | ~10% | No impact when closing |
The utilization and history length effects are independent. If you close a newer card, you only take the utilization hit. If you close your oldest card, you take both hits simultaneously. Never close your oldest card. If it carries an annual fee, call the issuer and ask for a product downgrade to a no-fee version — the account stays open, the history is preserved, and the fee disappears.
How Closing a Card Affects Your Utilization Ratio
Credit utilization — balances divided by total credit limits — is the second most heavily weighted factor in credit scoring at roughly 30%. Closing a card shrinks your total available credit, which raises your ratio even if your spending does not change.
| Scenario | Your Balances | Total Available Credit | Utilization |
|---|---|---|---|
| Before closing ($5,000-limit card) | $2,000 | $20,000 | 10% |
| After closing that card | $2,000 | $15,000 | 13.3% |
| Closing a $10,000-limit card instead | $2,000 | $10,000 | 20% |
| Closing a card while carrying high balances | $6,000 | $10,000 | 60% |
The damage scales with two factors: how large the closed card’s limit is relative to your total credit, and how much balance you are currently carrying elsewhere. A borrower who carries no balances across any card takes a smaller utilization hit than one carrying significant balances on other cards.
If you must close a card and you carry balances, pay down the balances first, then close. This minimises the utilization impact of the closure.
When Closing a Card Makes Sense
Annual fee that exceeds the benefits you actually use. A card charging $120–$150/year in exchange for travel lounge access, points, or insurance is only worth keeping if you use those features. If the card sits in a drawer and you collect 500 points per year that you never redeem, you are paying $120 for a credit score benefit that could be replicated with a no-fee product. In this case, close it — or better, ask for a downgrade.
Joint card after a divorce or separation. Joint credit card accounts leave both parties liable for the balance and any future spending by the other account holder. Closing a joint account after a relationship ends is a legitimate financial protection measure, regardless of the credit score cost. Get the balance to zero, then close it.
Fraud or security risk. A card you never use can be compromised and go unmonitored for months. If you have been notified of a breach or notice suspicious activity on a dormant card, closing it is appropriate. Credit score impact is secondary to financial security.
Simplification. Managing 6+ credit cards across multiple issuers adds administrative complexity — statements, payment dates, annual fee renewals. Consolidating to 2–3 active, high-limit cards is reasonable. Close the newest, lowest-limit cards with fees, and keep the oldest, highest-limit no-fee cards.
When to Keep an Old Card Open
No annual fee. A no-fee card costs nothing to hold. The ongoing benefit — maintaining utilization headroom and account age — is real, even if small. There is no scenario where keeping a no-fee card open hurts you; there are many scenarios where closing one does.
Your oldest account. The average age of your credit accounts is approximately 15% of your score. Closing your oldest card directly shortens this average. Even if it is an old card with a low limit and no benefits, downgrade it to a no-fee product and leave it open rather than closing it.
Your highest credit limit card. High-limit cards contribute the most to lowering your utilization denominator. A $15,000-limit card you rarely use is quietly doing useful work for your credit score each month by keeping your utilization ratio low.
Before any major credit application. Do not close any card within 3–6 months of applying for a mortgage, car loan, or large line of credit. The utilization increase and any score drop will appear on your report at the worst possible moment.
Alternatives to Closing
Before closing a card, consider options that eliminate the cost while preserving the credit benefit.
Product downgrade. Call the issuer and ask to switch your card to a no-fee version within the same product family. Most major Canadian card issuers — RBC, TD, Scotiabank, CIBC, BMO, American Express — offer both premium and no-fee variants of their core products. The account stays open, the credit history is preserved, the annual fee disappears, and your utilization denominator is unchanged. This is the right first move for any fee card you are considering closing — see Does Closing a Credit Card Hurt Your Credit Score? for the full score impact breakdown.
Freeze or cut the card. Keep the account open but remove the physical card. Some issuers allow you to lock a card through their app. Cutting the card still leaves the account active for credit reporting purposes while eliminating the risk of impulsive spending.
Make a small annual purchase. Card issuers can close inactive accounts on their end after extended dormancy, typically 6–24 months of no activity depending on the issuer. Making one small purchase per year — a coffee, a streaming subscription — and paying it off immediately keeps the account active without meaningful spending.
Timing: Avoid Closing Near Major Credit Applications
| Time Before Application | Recommended Action |
|---|---|
| 6+ months out | Safe window to close a fee card if needed |
| 3–6 months out | Avoid closing unless the fee is the current month — ask your broker first |
| Under 3 months out | Keep all accounts open; do not disrupt your credit profile |
This applies to mortgage applications, car loan applications, and any large personal loan or line of credit application. Mortgage lenders review your credit score at pre-approval and again close to the funding date — both pulls matter.
