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

Hummingbird Mortgages • 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.

How Property Type and Condition Influence Mortgage Financing

By Hummingbird Mortgages • August 19, 2026
Why the Property Matters When You’re Qualifying for a Mortgage When qualifying for a mortgage, lenders typically look at four core areas: Income Credit Down payment or equity The property itself Most buyers focus heavily on income, credit, and savings—and for good reason. But even if those boxes are checked, the property can still determine whether a mortgage is approved. Why Lenders Care About the Property From a lender’s perspective, the property is the collateral for the mortgage. In the unlikely event of default, they need to know the home can be sold quickly and at fair market value to recover their funds. Because of this, lenders are careful about the condition, value, and marketability of any property they finance. Homes that are in poor repair, unconventional, or overpriced can raise red flags—even when the borrower is well qualified. Appraisals Are Always Part of the Process Every mortgage requires an appraisal to confirm value. Insured mortgages (through CMHC, Sagen, or Canada Guaranty) often use an automated valuation model completed online. Conventional mortgages typically require a full, on-site appraisal by a certified appraiser. This appraisal is not optional and happens after an offer is accepted—not at the pre-approval stage. Why Pre-Approvals Aren’t a Guarantee A pre-approval is a great first step, but it only assesses you, not the property. Once you’ve made an offer, the lender must approve the specific home you’re buying. Understanding this upfront helps avoid surprises and confusion later in the process. The Risk of Buying Without a Financing Condition In competitive markets, buyers sometimes remove financing conditions to strengthen their offer. However, this comes with risk. If the appraisal comes back low—or the lender is concerned about the property’s condition—you could be denied financing after the offer is firm. In that scenario, your deposit may be at risk. Buying a Home That Needs Work If you’re considering a property that isn’t in perfect condition, there are solutions. A purchase plus improvements program allows you to buy a home and include renovation costs in your mortgage. The process is structured and requires planning, but it can be an excellent way to turn a fixer-upper into a great long-term investment. Final Thoughts Mortgage approval isn’t based solely on your finances—the property matters just as much. Knowing this ahead of time helps you make smarter offers, reduce risk, and plan more effectively. If you’re buying a property that needs work or want clarity on how a lender may view a specific home, feel free to reach out.

Co-Signing a Mortgage in Canada: Pros, Cons & What to Expect

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.
