If you’ve ever checked your credit score in Canada—whether through Credit Karma, TransUnion, or Equifax—you’ve likely noticed they rarely match. That discrepancy can be frustrating, especially when you’re in the market for a home, refinancing, or trying to qualify for the best mortgage rates. But behind these numerical differences lies a bigger financial reality. Your credit score isn’t just a number—it tells lenders how risky you are as a borrower, affecting your home buying power more than many people realize.
Why Your Score Isn’t the Same Everywhere
Each credit reporting agency—Equifax and TransUnion being the two main ones in Canada—uses its own proprietary formula to calculate your score. If you’re using a site like Credit Karma or Borrowell, you’ll actually be seeing a version of your TransUnion score. Meanwhile, major banks often pull from Equifax or use custom scoring models altogether.
Data differences play a big role here. One bureau might have a delayed update or be missing a specific account. Even late payments or closed accounts may show up on one report and not the other. That’s because lenders aren’t required to report to both agencies, and some only report to one. So yes, the data sets they use are often incomplete and inconsistent.
Then comes the math. While both Equifax and TransUnion give scores from 300 to 900, how they weigh payment history, outstanding debt, account age, and inquiries isn’t the same. This means your mortgage lender might be seeing a very different version of your creditworthiness from what’s in your personal finance app.
How Lenders Use Your Score
This difference matters most when you apply for a mortgage. Lenders often check your score to help determine whether you qualify, how much you can borrow, and the interest rate you’ll receive. In a competitive real estate market—where CREA reports that average house prices continue to outpace wage growth—a few points could impact your buying options.
While each lender sets its own credit score requirements, a score over 680 is often considered good, while anything over 740 is excellent. If your Equifax score is 720 but your TransUnion comes in at 685, that could affect whether you qualify for a promotional rate—or find yourself stuck with a standard one. Subprime lenders, who typically offer private mortgages, may accept lower scores, but that usually comes with higher interest and added risk.
Keep in mind, lenders don’t only look at your score. They may scrutinize your entire credit history, especially if you’re applying for a higher loan-to-value mortgage or purchasing a second property. Still, your score is often the gateway to more favourable financing.
Credit Clean-Up Tips to Boost Your Mortgage Options
If you’re planning to buy or refinance in the next 6–12 months, now’s the time to optimize your score. One of the fastest ways is by reducing your credit utilization—aim to use no more than 30% of your total available credit. That means if you have $10,000 in available credit across your cards, try to keep your balance below $3,000.
Also, avoid applying for too many credit products within a short window. Each inquiry can shave points off your score and signal risk to underwriters. Instead, focus on maintaining prompt, full payments and keeping those older credit lines open. The age of your credit accounts plays into your overall score, so hang on to that first credit card even if you rarely use it.
Another helpful move is to review both your TransUnion and Equifax reports for accuracy. You’re entitled to a free credit report annually from each bureau, and it’s worth checking for outdated or incorrect data. Something as simple as a wrongly reported late payment can cause an unnecessary dip in your score.
If cash flow is tight due to rising rates—especially with Bank of Canada rate hikes—consider exploring a HELOC or structured refinance. These tools can consolidate your debts while keeping your credit profile in better shape and helping you maintain liquidity.
