At Financial Canadian, we often receive questions about credit scores and how they differ between bureaus. Many Canadians wonder which credit bureau reports the lowest score.
Understanding the differences between Equifax and TransUnion can help you better manage your credit profile. In this post, we’ll explore why scores can vary and which bureau typically reports lower scores.
How Canadian Credit Bureaus Operate
The Two Major Players: Equifax and TransUnion
In Canada, Equifax and TransUnion dominate the credit reporting landscape. These organizations shape your financial profile, but their methods and outcomes can differ significantly.
Data Collection: A Complex Web
Equifax and TransUnion collect information from various sources, including banks, credit card companies, and other lenders. They compile this data into credit reports, which form the basis of your credit score. However, not all lenders report to both bureaus, which can lead to discrepancies in your credit reports.

Some credit card issuers might only report to Equifax, while others prefer TransUnion. This selective reporting can result in different information appearing on your credit reports from each bureau.
Scoring Models: Similar Yet Distinct
While Equifax and TransUnion use similar factors to calculate credit scores, they employ different scoring models:
- Equifax uses the Equifax Risk Score (range: 300 to 850)
- TransUnion uses the CreditVision Risk Score (range: 300 to 900)
These distinct models can lead to variations in your credit scores. TransUnion’s model might place more weight on recent credit behavior, while Equifax could emphasize long-term credit history. As a result, your TransUnion score could be higher if you’ve recently improved your credit habits, even if your Equifax score hasn’t reflected these changes yet.
The Impact on Your Financial Life
The differences between Equifax and TransUnion become particularly important when you apply for loans or credit cards. Lenders may check your score with either Equifax or TransUnion (or sometimes both). A significant disparity between your scores could affect your approval odds or interest rates.
For example, if you’re applying for a mortgage and your Equifax score is 750 while your TransUnion score is 700, the lender using TransUnion might offer you less favorable terms. This highlights the importance of monitoring both your Equifax and TransUnion credit reports regularly.
We at FinancialCanadian.com recommend checking your credit reports from both bureaus at least once a year. This practice helps you spot discrepancies, correct errors, and understand how lenders view your creditworthiness.
Now that we’ve explored how Canadian credit bureaus operate, let’s examine the specific factors that influence your credit scores and how they can vary between Equifax and TransUnion.
What Shapes Your Credit Score?
Payment History: The Foundation of Credit
Payment history forms 35% of your credit score. Late payments can reduce your score by 50 to 100 points, depending on their recency and frequency. A single 30-day late payment might appear on your credit report for up to seven years.

To maintain a strong payment history:
- Set up automatic payments for your bills
- Contact creditors immediately if you struggle to make payments (many will work out payment plans if you’re proactive)
Credit Utilization: The Less, The Better
Credit utilization accounts for approximately 20% to 30% of your score. It refers to the amount of available credit you use at any given time. Keeping your utilization below 30% is good, but aiming for 10% or less can further boost your score.
Pro tip: If you plan to apply for a major loan, pay down your credit card balances a few months in advance. This strategy can quickly improve your credit score by lowering your utilization ratio.
Credit History Length: Time Builds Trust
The length of your credit history comprises about 15% of your score. This factor favors individuals who have managed credit responsibly over an extended period. Scores tend to improve significantly after about seven years of credit history.
For those new to credit, consider becoming an authorized user on a family member’s long-standing credit card account. This can add years to your credit history overnight (potentially boosting your score).
Credit Mix: Variety Adds Value
Having different types of credit accounts (such as credit cards, personal loans, and mortgages) can positively impact your score. This factor accounts for about 10% of your score. However, don’t open new accounts solely for this purpose. Instead, focus on managing your existing accounts responsibly.
Credit Inquiries: New Credit’s Impact
New credit inquiries make up about 10% of your score. Each hard inquiry can lower your score by a few points and remains on your report for two years. Try to space out credit applications and avoid multiple inquiries in a short period.
When shopping for a mortgage or auto loan, complete all applications within a 14-day window. Credit scoring models typically count these as a single inquiry, minimizing the impact on your score.
Understanding these factors will help you manage your credit effectively across both Equifax and TransUnion. In the next section, we’ll explore how these two major credit bureaus compare and which one tends to report lower scores.
Equifax vs TransUnion: Which Reports Lower Scores?
Understanding Score Discrepancies
Equifax and TransUnion scores often differ, which can impact your financial decisions and loan applications. These discrepancies are common and expected.
Score Ranges and Typical Differences
Equifax scores in Canada range from 300 to 850, while TransUnion scores span from 300 to 900. This scale difference alone can lead to variations in reported scores.

A Financial Consumer Agency of Canada study found that 14% of Canadians have a difference of 50 points or more between their Equifax and TransUnion scores. This gap can determine loan approval or rejection.
Factors Contributing to Score Differences
Several elements cause variations between Equifax and TransUnion scores:
- Reporting Timelines: Lenders may report to each bureau at different times. Your credit card company might report to Equifax on the 1st of the month and TransUnion on the 15th. This timing difference can result in varying scores (especially if you’ve recently paid off a large balance or made a significant purchase).
- Data Accuracy: Each bureau may have slightly different information on file. A 2005 survey revealed that Canadians reported relatively high levels of stress and wasted time as a result of inaccuracies on their credit reports. These inaccuracies can lead to score discrepancies.
- Scoring Models: Both bureaus use similar factors to calculate scores but weigh these factors differently. TransUnion’s CreditVision Risk Score considers factors that affect scores and provides tips to improve your credit health.
Which Bureau Reports Lower Scores?
TransUnion tends to report slightly lower scores for many Canadians. This trend partly stems from TransUnion’s broader scoring range (300-900) compared to Equifax’s (300-850).
However, this isn’t a universal rule. Some consumers may find their Equifax score lower. The key is to monitor both scores regularly and understand what influences each one.
Practical Tips for Managing Your Scores
- Check Both Reports Annually: Use your free annual credit report from both Equifax and TransUnion to spot discrepancies and errors.
- Dispute Inaccuracies Promptly: If you find errors, file disputes with both bureaus immediately.
- Time Your Loan Applications: Check both your Equifax and TransUnion scores before applying for a major loan. Apply when both scores are at their highest, and consider asking the lender which bureau they use for credit checks.
- Maintain Consistent Credit Behavior: Pay all bills on time and keep credit utilization low across all accounts. This practice ensures positive reporting to both bureaus, minimizing score discrepancies.
Final Thoughts
Equifax and TransUnion shape your financial profile differently. TransUnion often reports lower scores due to its broader range, but this isn’t always true. Regular monitoring of both bureaus helps you spot discrepancies and understand your creditworthiness from a lender’s perspective.

Consistent, responsible credit behavior improves scores across all bureaus. Pay bills on time, keep credit utilization low, and avoid opening many new accounts quickly. These habits positively impact your scores, regardless of which credit bureau reports the lowest score.
