Key Takeaway

Your credit score in Canada is a three-digit number (typically between 300 and 900) that lenders use to assess your creditworthiness when you apply for a mortgage, loan, or credit card. The score is calculated by credit bureaus Equifax Canada and TransUnion Canada based on your payment history, credit utilization, length of credit history, types of credit, and recent inquiries. Improving your score takes time but can be done by paying bills on time, keeping credit utilization below 30 percent, avoiding unnecessary credit applications, and regularly checking your credit report for errors.

What Is a Credit Score?

A credit score is a numerical representation of your credit risk, calculated using information from your credit report. In Canada, scores typically range from 300 to 900, with higher scores indicating lower risk to lenders. According to the Financial Consumer Agency of Canada, most lenders consider a score above 660 to be good, while scores above 750 are considered excellent (FCAC, 2026).

The two main credit bureaus in Canada, Equifax Canada and TransUnion Canada, each maintain your credit file and calculate your score using their own proprietary models. While the exact formulas are not public, both bureaus use similar factors to determine your score.

Why Your Credit Score Matters

Your credit score directly affects your ability to borrow money and the cost of that borrowing. Lenders use your score to decide whether to approve your application for a mortgage, car loan, credit card, or line of credit, and what interest rate to charge you.

For mortgages in particular, your credit score plays a critical role alongside the OSFI stress test (B-20 guideline). Even if you can afford the mortgage payment at the higher qualifying rate, a low credit score may result in a declined application or a higher interest rate. A difference of just one percentage point on a mortgage rate can cost you tens of thousands of dollars over the life of the loan.

Credit scores also matter beyond borrowing. Landlords often check credit reports when screening tenants, and some employers review credit history for positions involving financial responsibility.

How Credit Scores Are Calculated in Canada

As explained in foundational personal finance texts such as Principles of Finance (OpenStax, 2022), credit scoring models weigh several factors to assess risk. In Canada, the main factors are:

Payment history (35 percent): Your track record of making payments on time is the single most important factor. Late payments, collections, and bankruptcies negatively impact your score. Even one missed payment can drop your score significantly.

Credit utilization (30 percent): This is the ratio of your current credit card balances to your total credit limits. Lenders prefer to see you using less than 30 percent of your available credit. For example, if you have a total credit limit of $10,000 across all cards, keeping your combined balance below $3,000 is ideal.

Length of credit history (15 percent): A longer credit history generally helps your score, as it gives lenders more data to assess your behaviour. This includes the age of your oldest account and the average age of all your accounts.

Types of credit (10 percent): Having a mix of credit types (credit cards, a car loan, a line of credit) can positively affect your score, as it shows you can manage different kinds of debt responsibly.

Recent credit inquiries (10 percent): Each time you apply for credit, a hard inquiry is recorded on your credit report. Too many inquiries in a short period can lower your score, as it may signal financial distress. Shopping for a mortgage or car loan within a short window (typically 14 to 45 days) usually counts as a single inquiry.

How to Improve Your Credit Score

Improving your credit score is a gradual process, but the steps are straightforward:

Pay every bill on time. Set up automatic payments or reminders for all your credit accounts. Payment history is the largest factor in your score, so consistency is critical.

Lower your credit utilization. Pay down credit card balances and avoid maxing out your cards. If possible, make multiple payments throughout the month to keep reported balances low.

Avoid opening too many new accounts at once. Each application triggers a hard inquiry, and opening multiple accounts in a short period can hurt your score. Apply for new credit only when necessary.

Keep old accounts open. Closing old credit cards shortens your credit history and reduces your total available credit, which can increase your utilization ratio. If an old card has no annual fee, consider keeping it open and using it occasionally.

Check your credit report regularly. You are entitled to a free credit report from Equifax Canada and TransUnion Canada once per year. Review your report for errors such as incorrect late payments, accounts that do not belong to you, or outdated information. Dispute any errors with the credit bureau in writing.

Diversify your credit mix. If you only have credit cards, responsibly adding a small installment loan (such as a car loan or line of credit) can help improve your score over time, provided you make all payments on time.

Common Mistakes to Avoid

One frequent mistake is assuming that checking your own credit report will hurt your score. When you request your own report, it is recorded as a soft inquiry and does not affect your score. Only hard inquiries from lenders impact your score.

Another mistake is closing credit cards immediately after paying them off. While it may feel satisfying, closing accounts can increase your credit utilization ratio and shorten your credit history, both of which can lower your score.

Finally, avoid co-signing loans unless you fully understand the risk. As a co-signer, you are equally responsible for the debt. If the primary borrower misses payments, your credit score will suffer.

Conclusion

Your credit score is a critical financial tool that affects your ability to borrow, the interest rates you pay, and even your housing and employment options. In Canada, building and maintaining a strong credit score requires consistent, responsible credit use: paying bills on time, keeping balances low, avoiding unnecessary credit applications, and regularly reviewing your credit report for accuracy.

While improving a low score takes time, the long-term benefits are substantial. A higher credit score can save you thousands of dollars in interest on a mortgage or car loan, open doors to better credit products, and provide financial flexibility when you need it most. Start with small, consistent steps, and your score will improve over time.
