What "too much debt" means to a lender
A lender does not begin with the size of your balances. It begins with your monthly payments measured against your gross monthly income, before tax. That comparison is a debt service ratio, and it decides more mortgage applications than any other single calculation. Lenders look at two versions: one that counts housing costs alone, and one that adds every other required debt payment on top. The second is the total debt service ratio, usually written as TDS.
The figure a lender uses is not the figure on your statement. Revolving credit is counted at its required minimum payment. A mortgage is counted at the qualifying rate the lender must test you against, which can be higher than the rate you would actually sign. That is why a household can feel comfortable month to month and still not clear a lender's test.
The ceilings federally regulated lenders commonly work to
Federally regulated mortgage lenders generally work to a total debt service ratio ceiling of about 44%, and they qualify an uninsured mortgage at the greater of the contract rate plus 2 percentage points and 5.25%. Both rules are described in OSFI Guideline B-20, the residential mortgage underwriting guideline from the Office of the Superintendent of Financial Institutions. If your ratio lands above that ceiling, a lender's own rules usually leave little room to approve the file as it stands.
| Measure | What it captures | Benchmark you may encounter |
|---|---|---|
| Total debt service ratio | Housing costs plus all other required debt payments, as a share of gross monthly income | Federally regulated lenders generally work to a ceiling of about 44% |
| Qualifying rate, uninsured mortgage | The rate used to test whether you can carry the payments | The greater of the contract rate plus 2 percentage points and 5.25% |
| Home equity line of credit limit | Revolving credit secured by your home | Generally limited to 65% of appraised property value at federally regulated lenders |
| Total secured borrowing | All secured lending registered against the property combined | Usually capped at 80% of appraised value |
The last two rows matter if you are comparing equity loans. A home equity line of credit and any other loan registered against the property share the same ceiling, so a large line of credit can leave no room for further secured borrowing even when your income would support it. Equity is not the same thing as borrowing capacity, and appraised value is not the same thing as cash you can access.
Where those ceilings do not apply
Lending in Canada is licensed provincially, so the regulator and the rules differ depending on who you are dealing with. The 44% expectation is a supervisory guideline for federally regulated lenders. A lender licensed and supervised by a province may set its own ratio limits, and a lender holding a loan on its own books can weigh your file differently from an institution that intends to sell the loan to an investor.
That flexibility cuts both ways. A higher tolerance for debt service usually comes with a higher cost of borrowing, because the lender is taking on more risk. Ask for the total cost of borrowing in writing, then compare the whole picture rather than the headline rate. The lowest rates are only available to the most qualified applicants.
How to work out your own numbers
Before you apply anywhere, run the same calculation a lender will run. The checks below take about an hour and will tell you more than an online eligibility screen.
- Add up your gross monthly income, before tax, from sources a lender can verify and that you expect to continue.
- List the housing costs a lender counts: your mortgage payment or rent, property taxes, heating, and condo fees where they apply.
- List every other required monthly payment: credit cards at their minimum, car loans, personal loans, student loans, and any support obligation.
- Add the housing costs to the other payments, then divide that total by your gross monthly income. That result is your total debt service ratio.
- Redo the mortgage payment using a qualifying rate rather than your contract rate, so the ratio reflects the test a lender would apply.
- Pull your credit reports from both Equifax Canada and TransUnion Canada, because a lender may see information that appears at one bureau and not the other.
- If you own property, note the appraised value and every existing charge registered against it before you shop for equity loans.
If your ratio lands close to or above the ceiling, the practical options are usually to reduce required monthly payments, to document more income, or to wait. Which of those fits your situation depends on your circumstances, and for a decision of this size it is worth speaking with a regulated professional.
When debt is too much no matter what the ratio says
A ratio is a snapshot. The clearer warning signs are behavioural and legal. Borrowing new credit to cover payments on older credit, paying only minimums month after month, and drawing on a revolving line of credit to make the mortgage payment all suggest the structure has stopped working, whatever the arithmetic says. If several of those signs look familiar, the Financial Consumer Agency of Canada's debt and borrowing resources set out options and borrower rights in plain language.
Canadian law also puts outer limits on the cost of borrowing. The Criminal Code criminal rate of interest is 35% per year under section 347. Where a province operates a licensed payday lending regime, the federal Payday Lending Regulations (SOR/2024-114) cap the cost of borrowing at $14 per $100 advanced. Some provinces set a cap lower than $14 per $100, and the lower cap applies. Quebec does not license payday lending, which effectively prohibits the model there. A payday loan is generally up to $1,500 for a term of 62 days or less, which makes it a poor fit for anyone trying to lower a debt service ratio.
Credit files carry their own timelines. A consumer proposal stays on a credit report for three years after completion, or six years from filing, whichever comes first. A first bankruptcy stays on a credit report for six years after discharge. Only a licensed insolvency trustee can administer a consumer proposal or a bankruptcy, so anyone else offering to handle one is not authorized to do it.
Why a quoted rate is a benchmark, not an offer
The Bank of Canada publishes the policy interest rate, the prime rate, conventional mortgage rates and Government of Canada benchmark bond yields. These are benchmarks, not offers, and no lender is obliged to lend at them. Fixed-rate mortgages in Canada are compounded semi-annually by law, which is one reason a headline rate and the figure that shows up in an amortization schedule do not always match what people expect.
What you are actually offered depends on your credit history, your documented income, your down payment, the property, the term, and whether the borrowing is secured. Two households can read the same published benchmark and be quoted two different rates on the same day.
loanmoose.ca is not a lender. It does not make loans, set rates, or make credit decisions. It is a matching and comparison service. Whether you are researching how to get a mortgage loan, comparing a loan for mortgage purposes, or weighing equity loans against unsecured borrowing, the numbers that decide the outcome are the ones a lender calculates on your file.
Where to check your file and where to take a complaint
Start with your own credit reports from Equifax Canada and TransUnion Canada. Then confirm who regulates the lender you are dealing with: complaints about federally regulated financial institutions go to the Financial Consumer Agency of Canada, while provinces license and supervise most other lenders. If a lender's numbers and yours do not match, ask for the calculation in writing before you sign anything.
