On November 21, 2024, OSFI (Office of the Superintendent of Financial Institutions) officially removed the mortgage stress test requirement for uninsured mortgage switches and transfers at renewal. This is one of the most borrower-friendly regulatory changes in years — it gives hundreds of thousands of Canadians the ability to shop for better rates at renewal instead of being trapped with their current lender.
What Changed
The Old Rules (Before November 21, 2024)
Under the previous B-20 guidelines, borrowers switching lenders at renewal needed to re-qualify under the stress test. The qualifying rate was the higher of their contract rate + 2% or the 5.25% floor. For many borrowers who took out mortgages during the 2020–2022 low-rate period, this was an impossible hurdle — even though they had been making payments without issue for years.
Example: A borrower with a $500,000 mortgage, $100,000 household income, and $600/month in other debts could afford their actual payments at 4.50% just fine. But qualifying at 6.50% (4.50% + 2%) would push their GDS/TDS ratios above the lender maximum. Under the old rules, they were stuck with their current lender.
The New Rules (After November 21, 2024)
| Scenario | Stress Test Required? |
|---|---|
| New purchase mortgage | Yes |
| Refinancing (increasing mortgage amount) | Yes |
| HELOC application | Yes |
| Switching lenders at renewal — insured mortgage | No (was already exempt) |
| Switching lenders at renewal — uninsured mortgage | No (NEW) |
| Renewing with your current lender | No (was already exempt) |
The change specifically targets uninsured mortgage switches. Insured mortgages (those with CMHC, Sagen, or Canada Guaranty insurance) were already exempt from the stress test when switching, because the insurer’s guarantee transfers with the mortgage.
Why This Change Was Necessary
The “Renewal Trap”
Between 2020 and 2022, Canadians locked in at historically low rates — many below 2.5%. When these borrowers came up for renewal in 2025 and 2026, they faced a problem:
| Factor | At Origination (2021) | At Renewal (2026) |
|---|---|---|
| Mortgage rate | 1.80% | 4.50% (offered) |
| Stress test qualifying rate | 5.25% (floor) | 6.50% (4.50% + 2%) |
| Monthly payment at contract rate | $2,025 | $2,747 |
| Monthly payment at qualifying rate | $2,984 | $3,535 |
Many of these borrowers could afford the higher contract rate payment at renewal ($2,747), but could not pass the stress test at the qualifying rate ($3,535). Under old rules, they could only renew with their current lender — which meant they had no negotiating leverage and often accepted higher-than-competitive rates.
The Competition Problem
Lenders knew that borrowers who could not switch were captive customers. Industry data showed that renewal rates offered to “trapped” borrowers were often 10–30 basis points higher than rates offered to borrowers who could credibly threaten to switch. Over a 5-year term on a $500,000 mortgage, 25 basis points costs approximately $6,250.
Who Benefits Most
| Borrower Profile | Benefit |
|---|---|
| Borrowed 2020–2022 at low rates, renewing now | Can finally shop around and switch for a better rate |
| Income has not kept pace with qualifying-rate increases | No longer disqualified from switching despite making all payments |
| Borrowers with higher debt loads | Stress test amplified the impact of other debts; removal levels the playing field |
| Self-employed borrowers | Income verification complexity made stress-test qualification harder; switching is now simpler |
How to Take Advantage at Renewal
Step-by-Step Process
| Step | Action | Details |
|---|---|---|
| 1 | Know your renewal date | Start shopping 120 days before maturity for rate holds |
| 2 | Get your current lender’s offer | Ask for their best renewal rate in writing |
| 3 | Shop competing lenders | Contact at least 3 lenders or a mortgage broker |
| 4 | Compare all-in costs | Rate, terms, prepayment privileges, penalties |
| 5 | Use competing offers as leverage | Bring the best outside offer back to your current lender |
| 6 | Switch if warranted | A mortgage broker or new lender handles the transfer |
What You Need to Switch
Even without the stress test, the new lender will still conduct basic underwriting:
| Requirement | Details |
|---|---|
| Credit check | Standard credit pull; no minimum score mandated by the rule, but lender-specific minimums apply |
| Property appraisal | The new lender may require an appraisal to confirm property value |
| Proof of payments | Evidence that you have been making mortgage payments on time |
| Title review | Standard title search and insurance |
| No increase in mortgage amount | The switch must be a straight transfer — same or lower balance |
Costs of Switching
| Cost | Typical Amount | Who Pays |
|---|---|---|
| Discharge/assignment fee (old lender) | $200–$400 | You |
| Legal/notary fees | $500–$1,000 | Often covered by new lender |
| Appraisal fee | $300–$500 | Often covered by new lender |
| Title insurance | $200–$400 | Often included |
| Net out-of-pocket | $0–$500 | Many lenders cover most costs |
Many lenders, especially monoline lenders and brokers, cover switching costs to win your business. Always ask about fee coverage as part of your negotiation.
What This Does NOT Change
| Still Requires Stress Test | Why |
|---|---|
| New purchase mortgage | Protects borrowers from overextending on new debt |
| Refinancing | You are increasing the mortgage balance — new debt |
| HELOC applications | New credit facility backed by home equity |
| Switch with balance increase | Any increase in the mortgage amount is treated as new borrowing |
The stress test remains the standard for all new mortgage originations. OSFI’s change was narrowly targeted at renewal switches to address the competition and fairness problem — not to broadly loosen mortgage qualification standards.
Impact on the Mortgage Market
For Borrowers
- Better rates at renewal: Increased competition means lenders must offer competitive renewal rates or lose the mortgage.
- More negotiating power: Even if you do not plan to switch, the ability to switch gives you leverage.
- Estimated savings: Industry analysts estimate the change could save renewing borrowers 10–25 basis points on average, worth $2,500–$6,250 per 5-year term on a $500,000 mortgage.
For Lenders
- Retention pressure: Banks can no longer rely on the stress test to lock in renewing borrowers.
- Competitive pricing: Lenders are adjusting renewal rate strategies to be more competitive.
- Volume shifts: Monoline and alternative lenders may gain market share as switching becomes easier.
Practical Examples
Example 1: The Typical 2021 Borrower
| Factor | Details |
|---|---|
| Original mortgage | $550,000 at 1.90% (2021) |
| Household income | $110,000 |
| Other debts | $500/month |
| Balance at renewal | $475,000 |
| Best rate available | 4.34% (monoline lender) |
| Current lender’s offer | 4.59% |
| Stress test qualifying rate | 6.34% (4.34% + 2%) |
| Could they qualify at 6.34%? | No — GDS would exceed 39% |
| Under new rules | Can switch to 4.34% without stress test |
| 5-year savings | ~$5,950 |
Example 2: Self-Employed Borrower
| Factor | Details |
|---|---|
| Original mortgage | $400,000 at 2.10% (2021) |
| Declared income | $85,000 (self-employed, income varies) |
| Balance at renewal | $345,000 |
| Current lender’s offer | 4.69% |
| Best available rate | 4.29% (credit union) |
| Under old rules | Would need to verify and stress-test income — often a barrier for self-employed |
| Under new rules | Can switch based on payment history |
| 5-year savings | ~$4,100 |
