Your credit card limit — the maximum amount you can charge to your card — is one of the most misunderstood aspects of Canadian credit. Here’s how limits are set, how to increase them, and how they affect your credit score.
What Is a Credit Limit?
A credit limit is the maximum balance you’re allowed to carry on a credit card at any given time. If your limit is $5,000, you cannot charge more than $5,000 without the transaction being declined (or, on some cards, triggering an over-limit fee or service).
Credit limits are set at the time of application and can be:
- Increased (by request or automatically)
- Decreased (if the issuer identifies risk or the account is not used)
- Fixed or flexible (some Amex cards have no pre-set limit — spending power adjusts to usage patterns)
How Issuers Set Your Credit Limit
Canadian credit card issuers use the following factors:
| Factor | Impact on Limit |
|---|---|
| Annual income | Higher income → higher limit |
| Credit score | 760+ → higher limit offers |
| Existing debt | High debt → lower limit |
| Credit history length | Longer history → more trust |
| Employment type | Salaried > contract > self-employed (all else equal) |
| The card product | Each card has a set min/max range |
Income is the dominant factor. Most issuers use a debt-to-income ratio to ensure credit is manageable relative to your earnings. A common rule of thumb: credit limits are often set around 1–3 months’ gross income for entry-level to mid-tier cards.
Minimum Credit Limits by Card Type
| Card Type | Typical Starting Limit |
|---|---|
| Student cards | $500–$1,000 |
| No annual fee entry-level | $1,000–$3,000 |
| Mid-tier (Visa Infinite, WE Mastercard) | $5,000–$10,000 minimum |
| Premium / Infinite Privilege | $10,000–$50,000+ |
| Amex (no pre-set limit) | Adjusts to usage patterns |
Note: Visa Infinite cards require a minimum $5,000 credit limit under Visa’s programme requirements. Visa Infinite Privilege requires $10,000+. If your creditworthiness supports a lower limit, you may be approved for a lower-tier card instead.
How Credit Limits Affect Your Credit Score
Your credit limit directly impacts your credit utilisation ratio — the second-largest factor in your Canadian credit score (after payment history):
$$ ext{Utilisation} = rac{ ext{Balance}}{ ext{Credit Limit}} imes 100%$$
| Utilisation | Credit Score Impact |
|---|---|
| Under 10% | Excellent |
| 10–30% | Good |
| 30–60% | Moderate negative |
| 60–80% | Significant negative |
| 80%+ | Severe negative |
Example: You have a $5,000 credit limit and a $3,000 balance. Your utilisation is 60% — a red flag for lenders. If your limit increases to $10,000 with the same $3,000 balance, utilisation drops to 30% — a significant improvement.
How to Request a Credit Limit Increase
Method 1: Online / App Request
Most major Canadian banks allow online limit increase requests:
- TD: EasyWeb or TD app → Account Services → Credit Limit Increase
- RBC: Online Banking → Credit Cards → Request Limit Increase
- BMO: BMO Online Banking → My Accounts → Credit Limit
- Scotiabank: Scotia OnLine → Credit Cards → Request Credit Limit Increase
- CIBC: CIBC Online Banking → My Accounts → Credit Limit Change
Method 2: Phone Request
Call the number on the back of your card. An agent can often process the request immediately and inform you whether a hard credit check is required.
Method 3: Automatic Increase
Many issuers proactively increase your limit after 6–12 months of:
- On-time payments (every payment, no missed or late)
- Responsible utilisation (below 30%)
- Regular card usage (the card is not idle)
Will a Credit Limit Increase Hurt My Score?
The short answer: possibly short-term, then positively long-term.
| Event | Score Impact |
|---|---|
| Hard inquiry at time of request | -5 to -15 points (temporary) |
| Limit approved, same spending | Utilisation drops → score improves |
| Net effect after 3 months | Usually positive |
Ask your issuer before requesting: “Is this a hard or soft credit inquiry?” Some issuers use a soft inquiry for existing customers (no score impact). Others always perform a hard pull.
What If Your Limit Is Too Low?
A low limit causes high utilisation even with modest balances. Strategies:
- Request an increase after 6+ months of on-time payments
- Apply for a second card — adds available credit (but requires a hard inquiry)
- Pay your balance mid-cycle before the statement date — lowers the reported balance and utilisation
- Keep low-limit cards open even if unused — closing them removes available credit and raises utilisation
Over-Limit Fees in Canada
Under Canadian federal regulations, issuers cannot charge an over-limit fee unless you opt in to over-limit coverage. By default, transactions that exceed your credit limit are declined. Check your cardholder agreement — if you have over-limit opt-in enabled, disable it to avoid surprise fees.
