Credit Score Basics: What It Is, Why It Matters, and How to Improve It
Understand how credit scores work in Canada, what factors affect your score, how to check it for free, and proven strategies to build excellent credit.
Your credit score is a three-digit number that can save you thousands of dollars—or cost you thousands. Whether you're applying for a mortgage, renting an apartment, or getting a phone plan, your credit score matters. Here's everything you need to know.
What Is a Credit Score?
A credit score is a number (typically 300-900 in Canada) that represents how likely you are to repay borrowed money. Lenders use it to decide:
- Whether to approve your application
- What interest rate to offer you
- How much credit to extend
Higher score = better rates = more money in your pocket.
Credit Score Ranges (Canada)
| Score | Rating | What It Means | |-------|--------|---------------| | 800-900 | Excellent | Best rates available, easy approvals | | 720-799 | Very Good | Great rates, most applications approved | | 650-719 | Good | Competitive rates, generally approved | | 600-649 | Fair | Higher rates, some applications denied | | 300-599 | Poor | Difficult to get credit, highest rates |
The Two Credit Bureaus in Canada
Canada has two main credit bureaus that track your credit history:
Equifax and TransUnion
Each maintains its own file on you, and your scores may differ slightly between them. Lenders may check one or both.
How Your Credit Score Is Calculated
Your score is based on five main factors:
1. Payment History (35%)
The biggest factor. Do you pay your bills on time?
- Payments 30+ days late hurt your score
- Collections and bankruptcies are major negatives
- Consistent on-time payments build strong credit
Tip: Set up automatic payments for at least the minimum due.
2. Credit Utilization (30%)
How much of your available credit are you using?
Formula: (Credit Used ÷ Credit Available) × 100
Example:
- Credit card limit: $5,000
- Current balance: $1,500
- Utilization: 30%
Target: Keep utilization below 30%, ideally under 10%.
Tip: Pay your balance before the statement closes, not just before the due date.
3. Credit History Length (15%)
How long have you had credit?
- Older accounts help your score
- Average age of all accounts matters
- Don't close your oldest credit card
Tip: Keep your first credit card open, even if you rarely use it.
4. Credit Mix (10%)
Do you have different types of credit?
- Credit cards (revolving credit)
- Car loans (installment credit)
- Mortgages (secured credit)
- Lines of credit
Tip: A healthy mix helps, but don't take on debt just to diversify.
5. New Credit Inquiries (10%)
How often are you applying for new credit?
- "Hard inquiries" (credit applications) slightly lower your score
- Multiple inquiries in a short time (mortgage shopping) count as one
- Too many new accounts can signal risk
Tip: Don't apply for multiple credit cards at once.

Common Credit Score Myths
Myth: Checking your score hurts it
Reality: Checking your own score is a soft inquiry with no impact.
Myth: Carrying a balance builds credit
Reality: Pay your full balance monthly. You build credit by having accounts and paying on time, not by paying interest.
Myth: Closing cards improves your score
Reality: Closing cards can hurt your score by increasing utilization and reducing history length.
Myth: Income affects your credit score
Reality: Income isn't part of your credit score calculation. A student can have a higher score than a CEO.
Myth: Debit cards build credit
Reality: Debit cards aren't reported to credit bureaus. Only credit accounts count.
