What Is the Mortgage Stress Test?
The Canadian mortgage stress test is a mandatory financial check introduced by the Office of the Superintendent of Financial Institutions (OSFI). It was first introduced in 2016 and has been updated several times. The purpose: ensure borrowers can still afford their mortgage payments even if interest rates rise after they sign.
In simple terms — you don't just qualify at the rate you're being offered. You must prove you could handle a rate that's 2% higher. If your mortgage rate is 3.84%, you're tested at 5.84%.
The 2026 Stress Test Rate — What Is It Right Now?
As of February 2026, the stress test qualifying rate is the higher of:
- Your contract rate + 2.00%, OR
- 5.25% (the floor rate, unchanged since 2021)
Since most 5-year fixed rates are currently between 3.69%–4.19%, the effective stress test rate for most borrowers is their contract rate + 2% (e.g., 3.84% + 2% = 5.84%).
| Your Offered Rate | Stress Test Rate | Which Rule Applies |
|---|---|---|
| 3.69% | 5.69% | Contract + 2% (higher) |
| 3.84% | 5.84% | Contract + 2% (higher) |
| 4.19% | 6.19% | Contract + 2% (higher) |
| 3.25% | 5.25% | Floor rate (higher) |
| 2.80% | 5.25% | Floor rate (higher) |
How the Stress Test Is Calculated — Real Examples
Lenders use two debt service ratios — GDS and TDS — to determine if you qualify. Both are calculated using the stress test rate, not your actual mortgage rate.
GDS — Gross Debt Service Ratio (max 39%)
GDS = (Monthly mortgage payment + monthly property tax + monthly heating + 50% of condo fees) ÷ Gross monthly income
TDS — Total Debt Service Ratio (max 44%)
TDS = (GDS costs + all other monthly debt payments) ÷ Gross monthly income
Household income: $160,000/year ($13,333/month)
Home price: $950,000 | Down payment: $95,000 (10%) → Mortgage: $855,000 (+ CMHC = ~$889,200 total)
Offered rate: 3.84% | Stress test rate: 5.84%
Monthly payment at 5.84% (25yr): ~$5,540/mo
Property tax: $7,500/yr = $625/mo | Heating: $150/mo
GDS = ($5,540 + $625 + $150) / $13,333 = 47.5% ❌ Too high!
At this income, you'd likely qualify for a home around $800,000 — or need a higher income or more down payment to reach $950K.
Mortgage: $900,000 | Rate: 3.84% | Stress test: 5.84% | Amortization: 25 years
Monthly payment at 5.84%: $5,820
Property tax: $7,200/yr = $600/mo | Heating: $150/mo
GDS = ($5,820 + $600 + $150) / Gross Monthly = 39% (max)
Required gross monthly income: $16,846 → $202,200/year household income
With no other debt, a couple each earning $108,000 ($216K combined) would qualify for a $900,000 mortgage.
Who Does the Stress Test Apply To?
The stress test applies to all federally regulated lenders in Canada. This includes:
- Banks (Big 5 + smaller chartered banks)
- Monoline lenders (MCAP, First National, RMG, etc.)
- Insurance companies offering mortgages
- Mortgage brokers placing mortgages with any of the above
Who Is Exempt?
- Private lenders — Not federally regulated, do not apply stress test. But rates are much higher (8–12%).
- Straight mortgage switches at renewal — Switching lenders at renewal without increasing the mortgage amount is technically exempt (OSFI's updated guidance). In practice, many lenders still do a credit check but don't stress test qualifying income.
- Some provincial credit unions — Credit unions are provincially regulated. Some provinces (e.g., BC, Alberta) apply the federal stress test; others (e.g., Ontario's FSRA) may have different rules. Confirm with the specific CU.
Changes to the Stress Test in 2026 — What's New?
As of February 2026, the following updates are relevant to GTA buyers:
1. 30-Year Amortization Expanded (August 2024)
First-time homebuyers purchasing any property, and all buyers purchasing new construction homes, can now access 30-year amortizations on insured mortgages. This significantly reduces stress test pressure by lowering your tested monthly payment.
Impact: A $900,000 mortgage at 5.84% (stress test rate) over 30 years costs ~$5,262/month tested, vs. ~$5,673 over 25 years. The longer amortization means you qualify for ~10% more home.
2. CMHC Insured Limit Raised to $1.5M (December 2024)
The maximum purchase price eligible for CMHC insurance rose from $1,000,000 to $1,499,999. This matters because insured mortgages get lower rates (currently 3.69% vs. 3.84% for uninsured) — and paradoxically, a lower rate means a lower stress test rate, meaning you qualify for more.
3. Floor Rate Unchanged at 5.25%
Despite calls from the real estate industry to lower the floor rate as the Bank of Canada cut rates, OSFI has kept the floor at 5.25% since 2021. This floor only applies when your contract rate is below 3.25% — currently not common, but relevant if rates continue falling in 2026.
7 Strategies to Maximize Your Mortgage Qualifying Power in 2026
Strategy 1: Get the Lowest Possible Rate
This is the single biggest lever. Every 0.25% reduction in your offered rate = 0.25% reduction in your stress test rate = more mortgage you can qualify for. On a $800,000 purchase, going from 4.39% (bank) to 3.84% (broker) reduces your tested payment by ~$340/month — allowing you to qualify on lower household income.
Action: Always use a mortgage broker who shops multiple lenders before accepting any bank offer.
Strategy 2: Maximize Your Down Payment to Cross the 20% Line
Wait — doesn't more down payment just reduce the mortgage amount? Yes, but crossing the 20% threshold (uninsured) vs. just under (insured) gives you access to 30-year amortization for non-first-time buyers. A 25-year vs. 30-year amortization can change your tested monthly payment by ~$500–700 on a large mortgage.
Strategy 3: Pay Down Existing Debts Before Applying
The TDS ratio (max 44%) includes all your debt payments. A $400/month car loan reduces your maximum mortgage by approximately $65,000. Paying it off before your mortgage application directly translates to more buying power. Even paying down credit card minimum payments helps — lenders calculate 3% of revolving credit balances as a monthly obligation.
Strategy 4: Add a Co-Borrower
A qualifying co-borrower (spouse, parent, sibling) adds their income to the calculation. This is especially powerful if one partner has a recent job change or self-employment income that lenders treat conservatively. Note: the co-borrower's debts also get included in TDS, so the net benefit depends on their income-to-debt ratio.
Strategy 5: Use the First-Time Buyer 30-Year Amortization
If you're a first-time buyer, you now qualify for a 30-year amortized insured mortgage. At a stress test rate of 5.84%, a $700,000 mortgage over 30 years has a monthly payment of ~$4,093 vs. ~$4,413 over 25 years. That ~$320 monthly difference changes your qualification income requirement by ~$12,000/year.
Strategy 6: Declare All Legitimate Income
Lenders can consider: salary, commissions (2-year average), bonuses (if consistent, 2-year average), rental income (50–80% of gross, depending on lender), child support received, investment income, and for self-employed — T4A income, business income (2-year notice of assessment average), and retained earnings. Many borrowers leave qualifying income on the table because their broker doesn't know to ask. We do.
Strategy 7: Compare Lenders — Qualification Rules Vary
While the stress test rate is standardized, lenders interpret GDS/TDS rules differently. Some allow up to 44% TDS for strong borrowers (default is 39%/44%); some B-lenders allow 44%/48% for slightly lower credit profiles. A mortgage broker accesses all these lenders with one application and knows which lender's model fits your specific situation.

Can I Get a Mortgage Without Passing the Stress Test?
Technically, yes — through private lenders or some provincial credit unions. But this comes at a real cost: private mortgage rates typically run 8–12%, compared to 3.69–3.84% through A-lenders. On a $700,000 mortgage, that's an extra $30,000–58,000 per year in interest. Private mortgages are a short-term bridge solution, not a long-term strategy.
The better approach: work with a mortgage broker before you give up on qualifying. There are often income sources, debt strategies, or lender options you haven't considered.
How to Get Pre-Approved and Know Your Real Qualifying Amount
The most reliable way to know your real stress-tested buying power before you start house hunting:
- Gather your documents — Last 2 years of NOAs (Notice of Assessment), T4s, pay stubs, and a list of your current debts and monthly payments.
- Contact a mortgage broker — A broker shops multiple lenders simultaneously and tells you the maximum qualifying amount across different scenarios.
- Get a full pre-approval (not just pre-qualification) — A full pre-approval includes a credit check and document review. It gives you a 120-day rate hold and a letter you can show real estate agents.
- Know your comfortable payment, not just maximum — Just because you qualify for $X doesn't mean you should borrow $X. Factor in utilities, maintenance, and lifestyle costs.
Stress Test FAQ
Q: Will the stress test be removed in 2026?
A: Unlikely. OSFI has repeatedly defended the stress test despite industry pressure to lower or remove it. It's considered a key tool to prevent mortgage defaults if rates rise again.
Q: My bank said I pre-qualify for X amount. Is that after the stress test?
A: If the bank ran a full pre-approval with income verification and credit check, yes. If it was a quick online pre-qualification based on self-reported info, it may not accurately reflect the stress test. Always confirm with a licensed professional.
Q: Does the stress test apply to a HELOC?
A: Yes. Home Equity Lines of Credit at federally regulated lenders are subject to the stress test. The qualifying payment is calculated at the stress test rate on the full HELOC limit, not just your current balance.
Q: If I port my mortgage to a new home, do I need to pass the stress test again?
A: When porting without increasing the mortgage amount, typically no stress test is required. If you need to borrow more (top-up), the additional amount is stress-tested. Rules vary by lender.
