Closing a credit card is one of the most misunderstood credit topics in Canada. Many people assume cancelling a card is responsible — but from a credit score perspective, an unused open card is usually better than a closed one. The key is understanding which cards are safe to close and which ones protect your score.
How closing a card affects your score: two mechanisms
Mechanism 1: Utilization ratio increases
When you close a card, that card’s credit limit disappears from your “available credit.” Your balances on other cards haven’t changed, but the denominator of your utilization ratio has shrunk.
| Scenario | Total Credit | Balance | Utilization | Score Effect |
|---|---|---|---|---|
| Before closing: 3 cards ($5K, $5K, $5K) | $15,000 | $3,000 | 20% | Healthy |
| After closing $5K card | $10,000 | $3,000 | 30% | Moderate concern |
| After closing $5K card (if balance was $5K) | $10,000 | $5,000 | 50% | Significant hit |
Mechanism 2: Average account age decreases (if closing an older card)
Credit scoring models reward long account histories. Closing your oldest card removes a significant anchor from your average account age.
| Scenario | Card Ages | Average Account Age |
|---|---|---|
| 4 cards: 12, 8, 5, 2 years old | All open | 6.75 years |
| Close the 12-year-old card | 8, 5, 2 years | 5.0 years |
| Close the 2-year-old card | 12, 8, 5 years | 8.33 years |
Closing an older card has more score impact on account age than closing a new one.
Which cards are safe to close
| Card Type | Safe to Close? | Why |
|---|---|---|
| New card (under 2 years old), low limit, no annual fee | ✅ Relatively safe | Little account age contribution; low limit impact |
| Newer card with high annual fee you can’t justify | ✅ Consider closing | Downgrade to no-fee version first if possible |
| Old card (5+ years), no annual fee, low or no balance | ❌ Keep open | Strong account age contribution; free to hold |
| Old card with high limit, no annual fee | ❌ Keep open | Major utilization benefit; free to hold |
| Store card with high interest, no annual fee | ❌ Keep open if low limit | Even store cards contribute to history |
| Duplicate card (you have 3 Mastercards) | ⚠️ Depends | Close the newest one with the smallest limit |
The annual fee question: when it is worth cancelling
If a card costs $120+/year and the rewards don’t justify the fee, the math may favour cancelling — even with a modest score impact:
| Option | Score Impact | Financial Impact |
|---|---|---|
| Cancel the card | −5 to −25 points (temporary) | Save $120+/year |
| Keep it open | No change | Lose $120+/year |
| Downgrade to no-fee version | ✅ No score impact | Save $120/year; keep account history |
Best approach: Before cancelling any annual fee card, call the issuer and ask:
- Can you waive the fee this year?
- Can I be downgraded to the no-fee version of this card?
Many Canadian issuers (TD, RBC, Scotiabank, etc.) offer product transfers that preserve your account history while eliminating the fee.
How to cancel a credit card with minimal score impact
If you decide to cancel:
- Pay the balance to zero — never close a card with a balance outstanding
- Redeem any outstanding rewards — points are forfeited on cancellation
- Ask about a product downgrade first — may preserve account history
- Cancel lower-limit or newer cards first — minimizes utilization and account age impact
- Wait 3–6 months after opening any new credit — stacking a cancellation on a recently opened account amplifies the score drop
- Call to cancel officially — do not just stop using the card; inactivity may lead to involuntary closure on the issuer’s terms, plus outstanding annual fee charges
Will a cancelled card still affect my credit report?
Yes — positively, for a long time:
| Status | Impact on Credit Report |
|---|---|
| Closed account (good standing) | Stays on report up to 10 years; positive payment history continues to count during this period |
| Closed account (missed payments before closing) | Negative history stays 6–7 years from date of last activity |
| Closed account — average account age | The account continues to count in average age calculations while it remains on the report |
The score damage from closing a card is primarily the immediate utilization increase — which is real but typically recovers within a few months as balances are paid down or the scoring model adjusts.
