Receiving a mortgage decline from a major Canadian bank is not a final verdict — it is one lender's assessment based on their specific criteria on a specific day. Canada's mortgage market has three distinct tiers (A lenders, B lenders, and private lenders), and a decline from one tier does not mean the next tier will say no. Understanding exactly why a bank declined your application is the first step to finding the right lender for your situation.

The 8 Most Common Reasons Banks Decline Ontario Mortgage Applications

1. Failing the Stress Test

Canada's federal mortgage stress test (OSFI B-20) requires all federally regulated lenders to qualify borrowers at the greater of 5.25% or the contract rate plus 2%. In a high-rate environment, this can disqualify otherwise strong borrowers who could comfortably afford their actual payment. Many Ontario borrowers who fail the bank stress test qualify easily with credit unions (not federally regulated) or B lenders.

2. Credit Score Below Threshold

Most major banks require a minimum credit score of 680 for insured mortgages and 680–720 for conventional mortgages. A score below this threshold — even due to a single collection account or a brief period of missed payments — will result in an automatic decline. B lenders accept scores from 550–600+, while private lenders focus on equity rather than credit score.

3. Insufficient Down Payment

Banks require a minimum 5% down payment for properties under $500,000, 10% for the portion between $500K–$999,999, and 20% for properties at $1M+. If your down payment is at the minimum threshold, some lenders will still decline based on their internal risk appetite.

4. Self-Employment Income Documentation

If you are self-employed and your income on paper (line 15000 of your Notice of Assessment) is significantly lower than your actual cashflow due to business deductions, banks will use the NOA income — not what you actually deposit. This is a systemic issue that disproportionately affects Ontario's large self-employed population and is specifically addressed by B-lender "stated income" programs.

5. Too Much Other Debt

Banks use two ratios: GDS (Gross Debt Service — mortgage costs as a percentage of income) and TDS (Total Debt Service — all debt payments as a percentage of income). If your TDS exceeds 44% of gross income, you will fail the bank's qualification. Consolidating existing debt before or as part of the mortgage transaction can bring these ratios into line.

6. Employment Situation

Banks prefer T4-employed borrowers with at least 2 years of continuous employment with the same employer. Contract workers, commission-based employees, recent new Canadians, and those with employment gaps often face declines even when their actual income is strong and stable.

7. Property Issues

Banks have strict rules about property condition and type. Properties with previous grow-op citations, unusual construction (steel frame, dome home, converted barn), significant disrepair, on leasehold land, or in very rural locations may be declined by A-lenders regardless of the borrower's creditworthiness. Private lenders are often the only option for non-conforming properties.

8. Recent Bankruptcy or Consumer Proposal

A-lenders require 2+ years of clean credit history post-discharge from bankruptcy or 2–3 years post-discharge from a consumer proposal. If you are within that window, you are effectively locked out of A-lending regardless of your current financial stability — but B lenders and private lenders have solutions.

What To Do Immediately After a Mortgage Decline

1. 1Ask the lender for the specific reason for decline in writing — you are entitled to this information
2. 2Do NOT apply to multiple banks in quick succession — each application is a hard credit inquiry, and multiple inquiries within a short period damage your score
3. 3Contact a licensed mortgage broker who works across all lender tiers and can assess your file holistically
4. 4Pull your own credit report from both Equifax and TransUnion — look for errors and dispute any inaccuracies before re-applying
5. 5If the decline was due to debt ratios, calculate whether consolidating debt would bring you within qualifying limits

Your Real Alternatives When a Bank Says No in Ontario

• B Lenders: Equitable Bank, Home Trust, MCAP, Street Capital — accept lower credit scores and more flexible income documentation
• Credit Unions: Not federally regulated, so no stress test requirement on some products; Meridian, FirstOntario, and others serve Ontario borrowers
• Monoline Lenders: Often more flexible than banks on property type and some income situations
• Private Lenders: MICs and individual investors who lend on equity — your last resort and your bridge to better rates
• Co-Borrower Addition: Adding a creditworthy family member to the application may satisfy A-lender requirements
