Do You Have to Pass the Stress Test at Renewal? 2026 Rules

On January 29, 2026 — its first quarterly release of the year — OSFI confirmed the Canadian mortgage stress test is staying exactly where it was. The minimum qualifying rate (MQR) for uninsured mortgages remains the greater of your contract rate plus two percentage points, or a 5.25% floor. The same release kept loan-to-income (LTI) caps on lenders' uninsured mortgage portfolios in place after their pilot period, and opened consultations on a consolidated Credit Risk Management Guideline and on governance accountability.

That settles the "will the rules change in 2026" question. It does not answer the one that actually matters at renewal: does the test apply to me at all?

For most people renewing in 2026, it does not — not because the rule loosened, but because of where it attaches: to newly underwritten mortgages, not renewals. Three exemptions now cover the large majority of the renewing book. Below is the decision tree, then the math for borrowers still inside the test.

TL;DR

• Renewing with your existing lender: no requalification. A same-lender renewal is not a new underwriting event.
• Straight switch to a new lender: exempt from the prescribed MQR. Uninsured switches since November 21, 2024 (OSFI); portfolio-insured low-ratio switches since December 16, 2024 (Department of Finance); transactionally insured switches for years before either.
• "Exempt from the MQR" is not "no underwriting." OSFI still expects B-20 due diligence and "appropriately stressed" debt-service ratios; a lender may still run its own test.
• Refinance, equity take-out, or a longer amortization: full stress test, every time. The uninsured straight-switch exemption permits no increase to the balance at all; the portfolio-insured regime allows at most $3,000 for transaction costs. Equity take-out forfeits the exemption under both.
• If you are inside the test at a ~4% contract rate, you qualify at ~6% — about $570/month more on a $500,000 mortgage than you would actually pay.

What the MQR is, and who sets it

The stress test is a qualifying-rate rule, not a payment rule. You pay your contract rate; you must demonstrate you could carry the payment at the higher qualifying rate. The gap between those two numbers is the entire mechanism.

It arrived in stages: insured mortgages in October 2016, uninsured (low-ratio) mortgages under Guideline B-20 effective January 2018, and the 5.25% floor standardized across both in June 2021. OSFI sets the MQR for uninsured mortgages and reviews the floor and buffer at least annually, using lender filings, vulnerability indicators, and consultation with the Department of Finance and the Bank of Canada; the Department of Finance sets it for insured mortgages. The last formal reaffirmation before 2026 came December 12, 2023. Our guide to how OSFI's minimum qualifying rate works covers the underwriting mechanics.

Branch 1 — You renew with your existing lender

No requalification. OSFI frames the MQR as applying to "most newly underwritten residential mortgagors" under B-20, and a same-lender renewal is not a new underwriting event. The supporting evidence is structural: none of OSFI's straight-switch exemptions — all of which address lender-to-lender transfers — would have been necessary if same-lender renewals were already caught. We flag this as inference from OSFI's framing, not a standalone OSFI statement on renewals.

You cannot be turned down at your own lender's renewal desk for failing a test you were never given — but renewal offers are typically anchored near posted rates, and your lender knows requalification anxiety is what keeps people from shopping. It is the wrong reason to stay.

Branch 2 — You do a straight switch to a new lender

A "straight switch" moves your existing mortgage to another lender at renewal without changing the deal: same balance, same remaining amortization. Three regimes exempt it, on three different dates.

Uninsured (conventional, 20%+ equity) — effective November 21, 2024. OSFI no longer expects federally regulated lenders to apply the MQR when an uninsured borrower transfers a stand-alone uninsured mortgage between federally regulated lenders, provided there is no increase to the remaining amortization period or the loan amount. Uninsured mortgages are estimated at over 70% of Canadian mortgages, so this change moved the most volume. Mechanics are in our renewal stress test exemption guide.

Portfolio-insured ("insurable") low-ratio — effective December 16, 2024. The Department of Finance amended the mortgage insurance rules to remove the MQR here too. The criteria are tighter and worth reading literally: the mortgage was originally underwritten at a federally regulated institution and previously assessed against the MQR; the amortization schedule stays the same; and the unpaid principal balance may rise by at most $3,000 to cover transaction costs. Equity take-out is explicitly not permitted.

Transactionally insured (less than 20% down). These have not required MQR requalification on a lender switch at renewal for years. The exemption traces to the Insurable Housing Loan Regulations codified in 2012 and was widely publicized when the October 2023 Canadian Mortgage Charter restated it — a clarification of existing fine print, not a new rule. That lineage rests on a single industry source rather than a primary regulatory document; treat the timing as directional and the effect as well established.

The caveat that matters most. OSFI's November 21, 2024 letter is explicit that even on an exempted straight switch, lenders must still apply sound B-20 underwriting: borrower due diligence, "conservatively calculated and appropriately stressed" debt-service ratios, and judgment aligned with their own risk appetite. A lender may still choose to stress-test you even though OSFI no longer requires it. The regulatory floor came down; individual credit policies did not automatically follow. Ask before you apply, and see how the stress test affects your 2026 renewal options for the borrower-side checklist.

Branch 3 — Refinance, new money, or a longer amortization

Here the exemption ends and the full MQR applies. Three triggers:

1. Refinancing or taking out equity. The uninsured exemption permits no balance increase; the portfolio-insured rules allow at most $3,000 for transaction costs, and equity take-out is not permitted under either. Cross those lines and it is a refinance, not a switch.
2. Extending your amortization beyond your existing contractual schedule. Re-amortizing to lower a payment is a common renewal request, and it forfeits the exemption.
3. Any new purchase or net-new origination, which none of the renewal exemptions touch.

The most expensive misunderstanding in the 2026 renewal cycle is assuming the exemption travels into a refinance. It does not. Our 2024–2026 Canadian mortgage reforms guide maps which reform applies to which transaction.

The qualifying math: what rate you actually get tested at

If you land in Branch 3, here is what the test costs. All figures use a $500,000 mortgage over a 25-year amortization and the Canadian semi-annual compounding convention.

Two takeaways. First, the 5.25% floor is effectively dormant. It only binds below roughly a 3.25% contract rate, and nothing is pricing there — a live posted 5-year fixed checked at 4.09% in early August 2026 gives a qualifying rate of 6.09%, driven entirely by the +2% buffer. Posted rates move weekly; re-check yours.

Second, across today's realistic contract rates the gap holds near $570–$580 a month. That is the extra carrying capacity you must prove on a $500,000 balance — not pay, prove. Run your own numbers through the stress test calculator, or see what rate you are stress-tested at today worked through as a scenario.

What happens after the MQR

There is a live question about whether the individual-borrower test survives the decade. OSFI's November 2024 guidance said it "will consider the continued need for a Superintendent-prescribed MQR for uninsured mortgage originations following the full and successful implementation of the LTI limit framework," and Superintendent Peter Routledge has floated portfolio-level LTI limits as an alternative or complement, shifting prudential burden onto lenders' books rather than individual applicants. The January 29, 2026 release then kept LTI caps in place beyond their pilot period — which supports two readings: LTI as a continuing complement to the MQR, or as the precondition for retiring it. OSFI has not said which, and we will not guess. Either way, do not structure a 2026 or 2027 renewal around the stress test disappearing. Our 2026 stress test explainer tracks changes as announced.

Bottom line

Both backdrops are quiet. The Bank of Canada held its policy rate at 2.25% on July 15, 2026 (Bank Rate 2.50%), a sixth consecutive hold, with three decisions left this year — September 2, October 28 and December 9. The MQR was confirmed unchanged January 29, 2026.

So the stress test is not the variable in your 2026 renewal. Whether you trigger it is. Renew in place or switch cleanly and you never meet it; ask for a dollar more than $3,000 over your balance, or a month more amortization, and you meet all of it at roughly contract-plus-two. Decide which transaction you are doing first — the qualification question answers itself after that.

For brokers: the discretionary-underwriting caveat in OSFI's November 2024 letter is the live risk on a straight-switch file, not the MQR. Confirm the receiving lender's actual policy before positioning an exemption to a client with a thin debt-service ratio.
