What is the mortgage stress test in Canada?
The mortgage stress test is a federal requirement introduced in 2018 that ensures borrowers can afford their mortgage if interest rates rise. All federally regulated lenders (Big Six banks, federally chartered credit unions) must stress-test every uninsured mortgage borrower at the qualifying rate — regardless of the actual contract rate offered.
The qualifying rate is the higher of:
- Your contract mortgage rate + 2 percentage points (e.g., a 4.09% contract rate is tested at 6.09%)
- The Bank of Canada's posted 5-year benchmark rate (currently 3.40% as of September 2026)
This rule applies to new home purchases and to borrowers switching lenders or refinancing at renewal. It does not apply when renewing with your existing lender under the same terms.
How the Bank of Canada September 2026 hold affects the stress test
The Bank of Canada held its overnight target rate at 2.25% on September 2, 2026, with the next decision set for October 28, 2026. The 5-year Government of Canada benchmark bond yield currently sits at 3.40%, which anchors the BOC's posted 5-year benchmark rate used for the stress test.
With inflation at approximately 3% (Statistics Canada CPI, July 2026), the BOC is in a cautious hold pattern. If the BOC cuts on October 28, the 5-year benchmark could eventually decline, lowering the stress test floor for new borrowers. If inflation persists, the benchmark could hold or rise.
Stress test at renewal: do you need to requalify?
Whether you need to pass a stress test at renewal depends on what you do:
| Renewal scenario | Stress test required? |
|---|---|
| Renew with same lender, same terms | Usually no — the lender may offer a renewal without re-qualifying |
| Switch to a new lender at renewal | Yes — new lender requires full stress test and requalification |
| Refinance at renewal | Yes — refinancing is treated as a new mortgage |
| Add co-borrower or change terms | Yes — new terms trigger stress test |
| Renew with increased borrowing | Yes — additional borrowing is stress-tested |
If you are considering switching lenders at renewal, start preparing now: gather pay stubs, Notice of Assessment, bank statements, and property tax statements. Check your prepayment penalty before switching — it may offset rate savings.
How to calculate your stress test payment
To estimate whether you can pass the stress test, model your mortgage payment at the qualifying rate:
- Find your contract rate. Check your renewal letter or current mortgage agreement.
- Add 2 percentage points. E.g., 4.09% + 2% = 6.09%.
- Compare to the BOC 5-year benchmark. Currently 3.40%. Use the higher of the two.
- Model the payment. Use the mortgage payment calculator on RateShop to see your payment at the qualifying rate.
- Check affordability. The payment at the qualifying rate should fit comfortably in your budget, not just barely pass.
Example: on a $400,000 mortgage at 4.09% over 25 years, the payment at contract rate is approximately $2,085/month. At the stress test rate of 6.09%, the payment would be approximately $2,588/month — a difference of roughly $503/month. Can you afford that?
September 2026 stress test snapshot
| Contract rate | Contract + 2% | BOC benchmark | Qualifying rate |
|---|---|---|---|
| 1.00% | 3.00% | 3.40% | 3.40% (benchmark wins) |
| 2.00% | 4.00% | 3.40% | 4.00% (contract+2 wins) |
| 3.00% | 5.00% | 3.40% | 5.00% (contract+2 wins) |
| 4.09% | 6.09% | 3.40% | 6.09% (contract+2 wins) |
| 5.00% | 7.00% | 3.40% | 7.00% (contract+2 wins) |
These are illustrative examples based on the BOC 5-year benchmark of 3.40% as of September 2026. Your actual qualifying rate depends on your lender, contract rate, and mortgage terms. Not offers or guarantees.
Tips to improve your stress test outcome
Before you apply
- Reduce your debt-to-income ratio — pay down credit cards and lines of credit
- Gather documentation: pay stubs, NOA, bank statements, property tax bills
- Check your credit report for errors — a higher credit score improves qualifying
- Compare the bank renewal offer to broker and monoline lender rates — a lower contract rate reduces the stress test burden
- Use the mortgage payment calculator to model different scenarios before signing
Compare rates that work with your budget
The stress test qualifying rate can make a big difference in what you can afford. Comparing current market rates — including broker and monoline options — may reveal a lower contract rate that reduces your stress test payment. RateShop can put renewal, switch, and purchase options side by side.

Frequently asked questions
What is the mortgage stress test qualifying rate in Canada 2026?
The qualifying rate is the greater of your contract rate + 2% or the BOC's posted 5-year benchmark rate (3.40% as of September 2026). Most borrowers with contract rates above 1.40% are tested at contract + 2%. See your lender for your exact qualifying rate.
How does the Bank of Canada rate hold affect the stress test?
The BOC held at 2.25% on September 2, 2026, keeping variable rates stable. The 5-year benchmark yield of 3.40% anchors the stress test floor. If the BOC cuts on October 28, the benchmark could eventually decline, lowering the stress test floor for new borrowers.
Do I need to pass a stress test when renewing my mortgage?
If you stay with your current lender, usually no. If you switch lenders, refinance, or change terms at renewal, yes — the new lender will require a stress test at the qualifying rate.
Can I pass the stress test if my payment would go up?
The stress test checks whether you can afford payments at the qualifying rate, not your current rate. Model your payment at contract + 2% using the mortgage payment calculator and compare to your budget.
What is the difference between the BOC benchmark and contract rate + 2%?
The stress test uses the higher of the two. At a 4.09% contract rate, contract+2% = 6.09%, which is higher than the 3.40% benchmark, so you are tested at 6.09%. At a 1.00% contract rate, contract+2% = 3.00%, lower than the 3.40% benchmark, so you are tested at 3.40%.
