How Your Loans and Spending Habits Are Quietly Shaping Your Credit Score

Kevin Roye • April 10, 2026

Your credit score is one of the most important numbers in your financial life — especially when it comes to getting a mortgage. But for most Canadians, how that number actually gets calculated remains a bit of a mystery.

Here's what you need to know.

What Is a Credit Score, Exactly?

A credit score in Canada ranges between 300 and 900 points. It's considered a predictor of how likely you are to pay your debt on time, and it directly affects a lender's decisions on loans, interest rates, and credit limits. The higher your score, the better.

In Canada, Equifax and TransUnion are the two primary organizations that collect data on consumer borrowing and provide credit scores to lenders. While both use similar inputs, their algorithms can differ — which is why your score may vary slightly depending on which bureau a lender checks.

Not All Loans Are Created Equal

You might assume that carrying a mortgage, a car loan, and a credit card all affect your score the same way. They don't.

Revolving credit products — like credit cards or a line of credit — can carry a higher influence on your credit score because they provide more insight into how you manage credit on a day-to-day basis. If you're regularly carrying a high balance or missing payments, that gets noticed quickly.

Instalment loans, such as auto loans, personal loans, or student loans, show your ability to manage a fixed scheduled payment. A mortgage, on the other hand, demonstrates your capacity to manage long-term balance repayment. Each type of credit tells lenders something different about your financial behaviour.

The Factors That Matter Most

Here's a breakdown of what actually moves your credit score:

1. Payment History

The biggest impact on your credit score comes from payment history — whether you're paying on time, and how long any bills have gone unpaid. Even one missed payment can leave a mark.

2. Total Amount Owed

This includes the total you owe across all creditors, how much you owe on specific types of accounts, and how much of your available credit you've used.

3. Credit Utilization

Your debt-to-credit utilization ratio — the amount you're borrowing compared to your total credit limit — matters significantly. Keeping that ratio below 30 to 40 per cent will help your score.

4. Length of Credit History

How long you've had credit products plays a role in your score calculation. This includes the age of your oldest account, your newest account, and the average age of all accounts. Closing old accounts can unintentionally lower your score.

5. Credit Inquiries

A credit inquiry for a new credit card or auto loan stays on your profile for six years. Checking your own score or getting a pre-approval doesn't affect your score — and when shopping for a mortgage, multiple inquiries are typically treated as a single event.

6. Unused Credit

Having a large amount of unused credit available can also negatively affect your score. Even if you don't owe anything on a $50,000 line of credit, a lender still has to factor in the fact that you have the capacity to take on that debt.

What This Means Before You Apply for a Mortgage

Your credit score doesn't just determine whether you're approved — it directly impacts the interest rate you're offered. A stronger score can mean thousands of dollars in savings over the life of your mortgage.

If you're planning to buy, renew, or refinance, it's worth taking a close look at your credit picture well in advance. Small changes — like paying down a credit card balance or avoiding new credit applications — can make a real difference in where your score lands when it counts.

For most Canadians, buying a home isn’t possible without a mortgage. And while getting a mortgage may seem straightforward—borrow money, buy a home, pay it back—it’s the details that make the difference. Understanding how mortgages work (and what to watch out for) is key to keeping your borrowing costs as low as possible. The Basics: How a Mortgage Works A mortgage is a loan secured against your property. You agree to pay it back over an amortization period (often 25 years), divided into shorter terms (ranging from 6 months to 10 years). Each term comes with its own interest rate and rules. While the interest rate is important, it’s not the only thing that determines the true cost of your mortgage. Features, penalties, and flexibility all play a role—and sometimes a slightly higher rate can save you thousands in the long run. Key Questions to Ask Before Choosing a Mortgage How long will you stay in the property? Your timeframe helps determine the right term length and product. Do you need flexibility to move? If a work transfer or lifestyle change is possible, portability may be important. What are the penalties for breaking the mortgage early? This is one of the biggest factors in the real cost of borrowing. A low rate won’t save you if breaking costs you tens of thousands. How are penalties calculated? Some lenders use more borrower-friendly formulas than others. It’s not easy to calculate yourself—get professional help. Can you make extra payments? Prepayment privileges allow you to pay off your mortgage faster, potentially saving years of interest. How is the mortgage registered on title? Some registrations (like collateral charges) can limit your ability to switch lenders at renewal without extra costs. Which type of mortgage fits best? Fixed, variable, HELOCs, or even reverse mortgages each have their place depending on your financial and life situation. What’s your down payment? A larger down payment could reduce or eliminate mortgage insurance premiums, saving thousands upfront. Why the Lowest Rate Isn’t Always the Best Choice It’s tempting to chase the lowest rate, but mortgages with rock-bottom pricing often come with restrictive terms. For example, saving 0.10% on your rate may put a few extra dollars in your pocket each month, but if the mortgage has harsh penalties, you could end up paying thousands more if you break it early. The goal isn’t just the lowest rate—it’s the lowest overall cost of borrowing . That’s why it’s so important to look beyond the headline number and consider the whole picture. The Bottom Line Mortgage financing in Canada is about more than rate shopping. It’s about aligning your mortgage with your financial goals, lifestyle, and future plans. The best way to do that is to work with an independent mortgage professional who can walk you through the fine print and help you secure the product that truly keeps your costs low. If you’d like to explore your options—or review your current mortgage to see if it’s really working in your favour—let’s connect. I’d be happy to help.

Co-Signing a Mortgage in Canada: Pros, Cons & What to Expect Thinking about co-signing a mortgage? On the surface, it might seem like a simple way to help someone you care about achieve homeownership. But before you sign on the dotted line, it’s important to understand exactly what co-signing means—for them and for you. You’re Fully Responsible When you co-sign, your name is on the mortgage—and that makes you just as responsible as the primary borrower. If payments are missed, the lender won’t only go after them; they’ll come after you too. Missed payments or default can damage your credit score and put your financial health at risk. That’s why trust is key. If you’re going to co-sign, make sure you have a clear picture of the borrower’s ability to manage payments—and consider monitoring the account to protect yourself. You’re Committed Until They Can Stand Alone Co-signing isn’t temporary by default. Even once the initial mortgage term ends, you won’t automatically be removed. The borrower has to re-qualify on their own, and only then can your name be taken off. If they don’t qualify, you stay on the mortgage for another term. Before agreeing, talk openly about expectations: How long might you be on the mortgage? What’s the plan for eventually removing you? Having these conversations upfront prevents surprises later. It Affects Your Own Borrowing Power When lenders calculate your debt service ratios, the co-signed mortgage counts as your debt—even if you never make a payment on it. This could reduce how much you’re able to borrow in the future, whether it’s for your own home, an investment property, or even refinancing. If you see another mortgage in your future, you’ll want to consider how co-signing could limit your options. The Upside: Helping Someone Get Ahead On the positive side, co-signing can be life-changing for the borrower. You could be helping a family member or friend buy their first home, start building equity, or take an important step forward financially. If handled with clear expectations and trust, it can be a meaningful way to support someone you care about. The Bottom Line Co-signing a mortgage comes with both risks and rewards. It’s not a decision to take lightly, but with careful planning, transparency, and professional advice, it can be done responsibly. If you’re considering co-signing—or want to explore safer alternatives—let’s connect. I’d be happy to walk you through what to expect and help you decide if it’s the right move for you.
