Mortgage Denied in Canada? Why It Happens and What to Do Next

Updated

A declined mortgage application is rarely the end of the road. Lenders decline against specific thresholds, so the reason for the decline tells you what has to change, how long that is likely to take, and whether a different lender would see the same application differently. This guide is part of our mortgage lenders and brokers guides.

Why mortgage applications get declined

Every lender checks the same handful of things. Falling short on any one of them can end the application.

ReasonWhat it meansHow often it comes up
Debt service ratios too highHousing costs (GDS) or housing plus other debts (TDS) take too large a share of gross income. For an insured mortgage, CMHC’s limits are 39% and 44%Very common
Failed stress testThe payments don’t fit your income at the qualifying rate rather than your actual rateVery common
Credit score too lowBelow the lender’s minimum, or below the score mortgage insurance requiresCommon
Down payment problemsNot enough saved, a source that can’t be traced, or gifted money without a gift letterCommon
Employment issuesProbation, a recent job change, gaps in work, or self-employment income that is too low on paperCommon
Property issuesLow appraisal, non-standard construction, zoning or environmental problemsModerate
Undisclosed debtsDebts found during verification that weren’t on the applicationModerate

The two ratio limits and the stress test are rules, not lender preferences:

  • For an insured mortgage, CMHC caps your housing costs at 39% of gross income (GDS) and your housing costs plus other debt payments at 44% (TDS); lenders set their own limits for uninsured mortgages. How each ratio is built is explained in GDS and TDS ratios.
  • Lenders check that you could afford the payments at the greater of your contract rate plus 2% or 5.25%, a floor set by OSFI for uninsured mortgages and by the federal government's mortgage insurance rules (the Minister of Finance's Eligible Mortgage Loan Regulations) for insured ones. See the mortgage stress test for worked examples.
  • For a CMHC-insured purchase, at least one borrower or guarantor needs a credit score of 600 or more; CMHC may use other ways to judge creditworthiness for a borrower with no credit history. What lenders want above that floor is covered in the credit score needed for a mortgage.

Step 1: Find out exactly why

Most lenders will tell you the reason if you ask, and the precise threshold you missed shows how much needs to change. Call the mortgage specialist or broker who handled the file and ask:

  • Which ratio failed, GDS or TDS, and by how much?
  • Was it the credit score? What is this lender’s minimum?
  • Did the appraisal raise a concern about the property?
  • Could the lender verify your income and your down payment?

Then pull your credit reports from both Equifax and TransUnion (the FCAC explains how to order them) and look for:

  • Errors: accounts that aren’t yours, wrong balances, or paid debts still shown as delinquent. Errors can be disputed with each bureau, and a dispute can take weeks.
  • Collections: old accounts sent to collections that you may have forgotten.
  • High balances: card balances that use a large share of their limits pull scores down (see credit utilization).
  • Missed payments: even one recent late payment can lower a score noticeably.

Step 2: Match the fix to the reason

If the problem is…What changes itTypical time
TDS too highPaying off or consolidating a debt payment, a larger down payment, or a lower price1-6 months
GDS too high or failed stress testA larger down payment, a lower purchase price, a co-borrower’s income, or a longer amortization where you’re eligible1-6 months
Credit score too lowOn-time payments, lower card balances, no new credit applications, disputing errors3-6 months for a meaningful change
Insufficient incomeA co-borrower, a raise, or a lender that counts more of your other income (rental, part-time, overtime)Varies
Down payment documentationA signed gift letter for gifted funds (a gift, not a loan) and 90 days of statements showing where the money came fromWeeks
EmploymentWaiting out probation, or a second full year of self-employment tax returns3-24 months
AppraisalRenegotiating the price, covering the gap with more down payment, or choosing another propertyImmediate
Where TDS is the limit, every $250 a month of debt payments removed supports roughly $36,000 to $42,000 more mortgage at qualifying rates between 7% and 5.25% on a 25-year amortization.

How each lever works is covered on its own page: qualifying for a larger mortgage, improving your credit score before you apply, what lenders look for in your bank statements, how credit card debt changes your maximum mortgage and changing jobs during the mortgage process. Down payment savings through an FHSA or the RRSP Home Buyers’ Plan are explained in how to save for a down payment.

If you’re self-employed

Lenders qualify self-employed borrowers on the income reported on their tax returns, not on business revenue, so heavy write-offs are a frequent reason for a decline. The options (declaring more income for two years, a lender that uses business-for-self programs, a larger down payment) are compared in getting a mortgage when self-employed, and stated-income mortgages explains how those programs verify income.

If it was a consumer proposal or bankruptcy

A recent insolvency usually means a B-lender or private lender first, then a move back to a bank once the record ages. The waiting periods are covered in a mortgage after a consumer proposal and a mortgage after bankruptcy.

Step 3: Choose where to apply next

The bank that declined you applied its own criteria. Another lender’s may fit your profile better, which is why the channel matters as much as the fix.

Rates for each lender type move with the market; current figures are on today’s mortgage rates.

Common mistakes after a decline

  • Applying at several more banks right away. Each application can add a hard inquiry, and if the problem is your ratios or your credit, the answer will be the same.
  • Taking on new debt to bridge the gap. A personal loan for the down payment raises your TDS and usually makes approval harder.
  • Misrepresenting anything on the next application. Mortgage fraud is a crime under the Criminal Code (up to 14 years in prison where the value exceeds $5,000). Lenders verify income, employment and the source of the down payment, and a material misrepresentation can lead to the mortgage being cancelled or called, and to criminal charges.
  • Treating it as permanent. Most reasons for a decline can be fixed within months.

How long before you can apply again

Starting pointTypical time to approval
TDS a few points over the limit1-3 months (pay off one debt)
Credit score a little under the lender’s minimum3-6 months (on-time payments, lower balances)
Credit score well below 6006-12 months of rebuilding
Self-employed for less than two years6-24 months (more tax returns)
Recent consumer proposal or bankruptcyDepends on discharge or completion date; see the two insolvency guides above
Low appraisal on one propertyImmediate (a different property)

Before reapplying, a broker or lender can do a preliminary review of the file, so the next formal application (and its credit check) goes only to a lender whose criteria you meet. The rest of the approval process, from pre-approval to the underwriting review, is covered in how the home buying process works.
