One of the biggest misconceptions I see is that people think they have to be completely debt-free to get a mortgage. That’s simply not the case. Lenders aren’t looking for financial perfection; they’re looking for evidence that you’re in control. Mortgage approval isn't about being debt-free—it’s about being debt-managed. Lenders are looking for a financial narrative that proves reliability, not perfection.
If you’re hoping to buy a home and already have some debt, it’s easy to assume it could get in the way. Many Canadians worry they’ll be turned down for a mortgage, approved for less than they need, or forced to put their plans on hold altogether.The reality is more nuanced. You can get a mortgage in Canada with debt. What matters most is how that debt fits into your overall financial picture — not just how much you owe.
Lenders look at factors like your income, credit score, and monthly payment obligations to determine whether a home loan is affordable for you. In other words, they’re assessing how manageable your debt is, not expecting you to be completely debt-free.
Understanding how this process works — and what steps can improve your chances — can help you move forward with more clarity and confidence. While a mortgage broker can help you find the right lender, Credit Canada focuses on helping you get financially ready, with trusted, non-judgmental support to strengthen your debt management and overall financial position before you apply.
How Canadian Lenders Evaluate Your Mortgage Application
When you apply for a mortgage, lenders aren’t simply looking at whether you have debt. They’re assessing risk. Their goal is to understand how likely you are to keep up with your payments over time.
Carrying some level of debt is more common than many people think, and it doesn’t automatically prevent you from qualifying for a mortgage.
The Basics of Mortgage Eligibility
In Canada, most lenders will look at a combination of:
- Income and employment stability: A steady income shows you can support regular payments
- Credit score: A snapshot of how you’ve managed credit over time
- Existing debt obligations: Not just balances, but your monthly payments
- Down payment: The more you can put down, the lower the risk for the lender
No single factor determines the outcome. Instead, lenders look at how everything works together. It’s entirely possible to qualify for a mortgage with debt if the rest of your financial picture is strong.
What Is Debt-to-Income (DTI) Ratio?
One of the most important pieces of the puzzle is your debt-to-income ratio — commonly referred to in Canada as your Gross Debt Service (GDS) and Total Debt Service (TDS) ratios.
These ratios measure how much of your income goes toward housing and debt payments.
- GDS ratio: The percentage of your income spent on housing costs (mortgage, property taxes, heating, etc.)
- TDS ratio: The percentage of your income spent on all debts, including housing, credit cards, loans, and other obligations
As a general guideline, many lenders look for:
- GDS below 39%
- TDS below 44%
If your ratios fall within these ranges, your chances of mortgage approval are typically stronger — even if you’re carrying some debt.
Types of Debt and How Each Affects Mortgage Approval
Not all debt is treated equally. In fact, different types of debt can affect your mortgage application in different ways.
Credit Card Debt
Credit card debt is often the most challenging from a lender’s perspective. Because it’s revolving and typically carries higher interest rates, it can:
- Increase your monthly payment obligations
- Lower your credit score if balances are high
- Signal a higher level of financial risk
Even if your balance seems manageable, high utilization can impact both your debt ratio and your overall mortgage eligibility.
Student Loans
Student debt is common across Canada, and lenders are used to seeing it.
However, even if your loan is in a grace period, lenders may still factor in an estimated monthly payment when calculating your debt ratios. This helps them assess your future financial commitments.
That said, student loans are generally viewed more favourably than high-interest debt, especially when payments are consistent and manageable.
Auto Loans and Personal Loans
Auto loans and personal loans are more straightforward for lenders to evaluate. They typically come with:
- Fixed monthly payments
- A defined repayment schedule
Because of this predictability, they’re easier to account for in your debt ratio — even though they still impact how much you can borrow.
Lines of Credit
Lines of credit can be a bit less predictable.
Even if you’re not actively using them, lenders may consider:
- Your total available credit
- A potential minimum payment
This means that even unused credit can influence your overall financial assessment and borrowing capacity.
How to Improve Your Mortgage Approval Chances When You Have Debt
If you’re carrying debt, there are still clear, practical ways to strengthen your application. In many cases, small adjustments can make a meaningful difference.
Pay Down High-Interest Debt First
If you’re deciding where to focus your efforts, start with high-interest debt — especially credit cards.
Reducing these balances can:
- Lower your monthly obligations
- Improve your credit score
- Bring down your overall debt ratio
For some Canadians, strategies like debt consolidation or working with a Credit Counsellor can help simplify this process and make repayment more manageable. If you’re considering this option, it’s worth understanding how debt consolidation can affect your ability to buy a home.
Improve or Stabilize Your Credit Score
Your credit score plays a key role in both mortgage approval and the interest rate you’re offered.
To strengthen it:
- Make all payments on time
- Keep balances low relative to your credit limits (ideally under 30%)
- Avoid taking on new debt shortly before applying
Even incremental improvements can expand your options when it comes to lenders and loan terms.
Increase Your Down Payment
A larger down payment reduces the amount you need to borrow — and lowers the lender’s risk.
It can also:
- Improve your debt ratios
- Reduce mortgage insurance costs (or eliminate them if you put down at least 20% of the purchase price)
- Potentially lead to better interest rates
If you have flexibility here, it can be one of the most effective ways to strengthen your application.
Consider Adding a Co-Applicant
In some cases, adding a co-applicant can strengthen your application by increasing your total household income. This can improve your debt ratios and potentially expand how much you’re able to borrow. However, it’s important to understand that a co-applicant shares full responsibility for the mortgage, including repayments, so it’s a decision that should be carefully considered.
Work with a Mortgage Broker
A mortgage broker can help match you with lenders who are more flexible when it comes to debt. Because they work with a range of lenders — including those outside of major banks — they may be able to identify options that better align with your financial profile. This can be especially helpful if your debt ratios or credit history fall outside of more traditional lending criteria.
What to Expect During the Mortgage Application Process
Understanding what the process looks like can help reduce uncertainty — especially if you’re concerned about how your debt will be viewed.
Pre-Approval vs. Final Approval
- Pre-approval gives you an estimate of how much you may be able to borrow based on your current financial situation
- Final approval happens after you’ve selected a property and the lender completes a more detailed review
Pre-approval is a helpful first step, but it’s not a guarantee. Your full financial profile will still be assessed before final approval is granted. It’s also important to avoid taking on new debt after you’ve been pre-approved or approved for a mortgage, as this can impact your final approval and borrowing terms.
Common Follow-Up Requests
It’s normal for lenders to ask for additional information, particularly if you have existing debt.
You may be asked to provide:
- Recent account statements
- Proof of income and employment
- A brief explanation of certain debts or financial decisions
These requests are part of the process and help lenders fully understand your situation — they don’t necessarily indicate a problem.
The Bottom Line
Having debt doesn’t mean homeownership is out of reach. Many Canadians successfully qualify for a mortgage while managing student loans, credit cards, or other financial obligations.
What matters most is how your debt fits into your overall financial picture — and whether it’s manageable based on your income and spending.
