Key Takeaway

Your credit score in Canada ranges from 300 to 900 and is calculated by two bureaus: Equifax and TransUnion. It determines whether you qualify for mortgages, credit cards, and loans, and at what interest rate. The five main factors are payment history (35%), credit utilization (30%), length of credit history (15%), credit mix (10%), and new credit inquiries (10%). You can improve your score by paying bills on time, keeping credit card balances below 30% of your limit, and checking your free annual credit report for errors.

What Your Credit Score Means for Your Finances

In Canada, your credit score is a three-digit number that lenders, landlords, insurers, and even some employers use to assess your financial reliability. A higher score unlocks better mortgage rates, higher credit limits, and easier approval for loans. According to the Financial Consumer Agency of Canada, most Canadian lenders consider a score above 650 acceptable, while 750 and above is excellent (FCAC, 2026). Understanding how the score is calculated and what actions improve it can save you thousands of dollars in interest over your lifetime.

1. What Is a Credit Score and Who Calculates It?

A credit score is a numerical summary of your creditworthiness, ranging from 300 (poor) to 900 (excellent) in Canada. Two private credit bureaus, Equifax and TransUnion, collect data from lenders (banks, credit card issuers, utilities, telecom companies) and use proprietary algorithms to calculate your score. Each bureau may have slightly different information, so your Equifax score and TransUnion score can differ by a few points. Lenders typically pull from one or both bureaus when you apply for credit. The score itself is not reported to lenders by law, but many lenders calculate it using the data in your credit report.

2. Payment History: The Biggest Factor (35%)

Your payment history, the single most important component, tracks whether you pay bills on time. A single missed payment (30 days or more overdue) can drop your score by 50 to 100 points and remain on your report for six years in most provinces (longer in some cases, such as Quebec for certain records). To protect this factor, set up automatic payments for at least the minimum due on credit cards and loans, and pay all bills by the due date. Even utility and phone bills matter: if sent to collections, they appear on your credit report and damage your score.

3. Credit Utilization: Keep It Below 30% (30%)

Credit utilization is the ratio of your current credit card balances to your total credit limits. For example, if you have two cards with a combined limit of $10,000 and owe $2,000, your utilization is 20%. Lenders view high utilization (above 30%) as a sign you are overextended. To improve this factor, pay down balances before the statement closing date (not just the due date, because the balance reported to the bureaus is typically the statement balance), and avoid closing old credit cards, which lowers your total available credit and raises your utilization ratio. Requesting a credit limit increase, if you can avoid spending more, also helps.

4. Length of Credit History: Older Is Better (15%)

This factor measures the average age of your credit accounts and the age of your oldest account. A longer credit history demonstrates stability. Closing your oldest credit card, even if you no longer use it, can shorten your average account age and lower your score. Keep old accounts open and use them occasionally (a small purchase every few months) to keep them active. If you are new to credit, consider becoming an authorized user on a family member’s longstanding, well-managed card, or apply for a secured credit card to start building history.

5. Credit Mix: Variety Signals Reliability (10%)

Lenders like to see that you can manage different types of credit: revolving credit (credit cards, lines of credit) and installment loans (car loans, personal loans, mortgages). You do not need one of each, but having only credit cards, for instance, is less favourable than having a mix. Do not take on debt you do not need just to improve your mix, but when you do borrow (for a car, for example), recognize that on-time payments contribute positively to this factor and to your overall score.

6. New Credit Inquiries: Limit Hard Checks (10%)

Every time you apply for credit, the lender performs a hard inquiry (hard pull) on your credit report, which can lower your score by a few points. Multiple hard inquiries in a short period suggest you are desperate for credit or taking on too much debt. The impact is small and fades after a year, but inquiries remain visible on your report for three years (as covered in foundational texts such as Introduction to Business from OpenStax). When rate-shopping for a mortgage or auto loan, multiple inquiries within a 14 to 45 day window (depending on the scoring model) typically count as a single inquiry. Avoid applying for multiple credit cards or loans at once, and check your own credit report regularly: self-checks are soft inquiries and do not affect your score.

7. Check Your Credit Report for Free and Dispute Errors

Under federal law, Equifax and TransUnion must provide you with a free copy of your credit report once per year (by mail; online reports may carry a fee). Request your report from both bureaus, review every entry, and dispute any errors: incorrect late payments, accounts that do not belong to you, or outdated information. According to the Ontario Securities Commission’s financial literacy resources, even a single corrected error can improve your score significantly (OSC, 2026). The dispute process is free and can be done online or by mail; the bureau must investigate within 30 days.

8. Quick Wins to Improve Your Score in 30 to 90 Days

For immediate improvement, pay down credit card balances to below 30% utilization (ideally below 10%), set up automatic payments to ensure no missed due dates, and ask your credit card issuer for a credit limit increase if your income has risen and you have a history of on-time payments. Becoming an authorized user on a family member’s high-limit, low-balance card can also raise your score within one billing cycle, as long as that account reports to the bureaus. Avoid closing accounts, and if you have any outstanding collections, negotiate payment or settlement and request a letter confirming the debt is resolved.

Conclusion

Your credit score in Canada is a powerful financial tool that affects your borrowing costs, housing options, and even employment prospects. By understanding the five factors (payment history, utilization, history length, credit mix, and inquiries) and taking deliberate steps to strengthen each one, you can build and maintain a strong score. Check your free annual report from Equifax and TransUnion, correct any errors, and develop habits that protect your score over the long term.
