Should You Switch Lenders or Stay at Renewal?

Direct answer

Renewing with your incumbent is never prescribed-MQR tested. An uninsured like-for-like switch has been exempt from the prescribed Minimum Qualifying Rate since 21 November 2024 under the OSFI straight-switch rule. A refinance with extra funds, extra debt, or a longer amortization is always tested at the greater of contract plus 2% or 5.25%.

2026 Canadian Mortgage Renewal Guide: 120–180 Day Rate Strategy & OSFI Rules Explained

Canadian homeowners renewing in 2026 can lock a rate 120–180 days before maturity. Stay with the current lender and the prescribed MQR never applies. An uninsured FRFI straight switch has been exempt since 21 November 2024 when loan amount and remaining amortization do not rise. Portfolio-insured low-ratio switches followed on 16 December 2024. Extra money or a longer amortization is always tested.

2026 Mortgage Renewal Canada: OSFI Straight Switch Rules, CMHC Insurance & Your Survival Guide

Facing a mortgage renewal in 2026? Canada's renewal landscape has shifted significantly — with OSFI's (Office of the Superintendent of Financial Institutions) straight switch exemptions, updated portfolio LTI (Loan-to-Income) limits now in full effect, and expanded 30-year amortization eligibility for first-time buyers. This guide breaks down exactly what you need to know to negotiate smarter, avoid unnecessary stress tests, and protect your financial stability through renewal.

Switching Mortgage Lenders at Renewal in Canada: 2026 Straight-Switch Guide (No Stress Test)

Switch lenders at renewal without the prescribed MQR when the file stays a straight switch. Uninsured FRFI transfers have been exempt since 21 November 2024 if loan amount and remaining amortization do not rise — credit unions are not FRFIs. Portfolio-insured low-ratio switches followed on 16 December 2024 (unpaid principal may rise by at most $3,000 for costs; no equity take-out). High-ratio insurance transfer is a different path. Extra money or a longer amortization is always tested at the greater of contract + 2% or 5.25%. Guideline B-20 overlays can still apply.

Uninsured straight switch: untested since 21 November 2024 OSFI dropped the prescribed MQR if loan amount, remaining amortization, and payment schedule do not increase. Insured straight switches were already exempt. Portfolio-insured low-ratio switches: Finance, 16 December 2024, at most $3,000 extra for transaction costs.

Refinance is always tested Equity-out, extra debt, or a longer amortization faces the full MQR (greater of contract + 2% or 5.25%).

Exempt from MQR is not no underwriting The receiving lender may still apply B-20 due diligence and its own stressed debt-service test. Confirm in writing before you apply.

The 2026 renewal choice is stay, straight-switch, or refinance — and only refinance is prescribed-MQR tested. Stay with your incumbent and there is no prescribed Minimum Qualifying Rate. An uninsured straight switch (same loan amount, remaining amortization, and payment schedule) has been exempt from the prescribed MQR since 21 November 2024; insured straight switches were already exempt. Taking equity out, adding debt, or stretching amortization is a refinance and always faces the full MQR (greater of contract + 2% or 5.25%). Use the renewal calculator for stay-vs-switch payments, and refinance break-even when the file is no longer a straight switch.

Stay with the incumbent: no prescribed MQR Renewing in place is not a new underwriting event. OSFI does not apply the prescribed Minimum Qualifying Rate when you stay with your current lender on the existing balance and remaining amortization.

Uninsured straight switch: untested since 21 Nov 2024 OSFI exempted uninsured mortgage straight switches from the prescribed MQR on 21 November 2024 if the loan amount, remaining amortization, and payment schedule do not increase. Insured (transactionally insured) straight switches were already exempt. Portfolio-insured low-ratio switches followed on 16 December 2024, with at most $3,000 extra for transaction costs.

Refinance is always tested Equity-out, extra debt, or a longer amortization is a refinance. The receiving lender applies the full MQR — the greater of contract rate + 2% or the 5.25% floor — every time.

Exempt from MQR is not no underwriting The receiving lender may still run Guideline B-20 due diligence and its own stressed debt-service test. Ask the new lender in writing whether it will apply a discretionary stress test before you apply.

Stay is untested. A qualifying straight switch is untested. A refinance is always tested.

  • Stay with incumbent: no prescribed MQR. This is not a newly underwritten mortgage.
  • Uninsured straight switch: OSFI stopped expecting the prescribed MQR on 21 November 2024, provided loan amount, remaining amortization, and payment schedule do not increase. Source: OSFI letter.
  • Insured straight switch: transactionally insured transfers at renewal were already outside the prescribed MQR.
  • Portfolio-insured low-ratio switch: Department of Finance, 16 December 2024 — amortization unchanged; unpaid principal may rise by at most $3,000 for transaction costs; equity take-out is not permitted.
  • Refinance (equity-out, extra debt, longer amort): always the full MQR — greater of contract + 2% or 5.25%.
  • Caveat: exemption from the prescribed MQR is not a waiver of B-20. The receiving lender can still run its own due diligence and a discretionary stressed GDS/TDS test.

Run stay-versus-switch payments on the renewal calculator. If the file will increase the balance or amortization, use refinance break-even instead — that path is inside the test.

OSFI 21 November 2024 Uninsured stand-alone mortgages transferring between federally regulated lenders: no prescribed MQR if loan amount and remaining amortization do not increase.

B-20 still applies OSFI still expects borrower due diligence and conservatively calculated, appropriately stressed debt-service ratios. Individual credit policy can be stricter than the prescribed-MQR floor.

The MQR question at renewal is about the transaction, not just the insurance stamp — but insurance still changes which exemption date applies.

  • Uninsured (typically 20%+ equity): same-lender stay has no prescribed MQR. A straight switch to another FRFI has had no prescribed MQR since 21 November 2024 if amount, remaining amortization, and payment schedule stay put.
  • Transactionally insured (high-ratio / less than 20% down at origination): straight switches at renewal were already outside the prescribed MQR. Insurer rules still cap amortization (standard 25 years; 30 years only where the first-time / new-build rule applies) and the insurance remains on the file.
  • Portfolio-insured low-ratio: Finance's 16 December 2024 change removed the MQR on a straight switch, with a $3,000 transaction-cost cap on any principal increase.
  • Any of the above plus new money or a longer amort: that is a refinance. Insurance status does not save you from the MQR.

Insured files still follow insurer + OSFI constraints on amortization and insurance premiums. Uninsured files have more amortization flexibility — but using that flexibility on a lender change exits the straight-switch exemption.

See Do you have to pass the stress test at renewal? for the three-branch tree.

Insurance does not decide stay-vs-switch MQR by itself Stay is untested in both books. Switch MQR depends on whether the move is a straight switch under the matching OSFI or Finance exemption.

Amortization flexibility is a refinance trigger Resetting remaining amort longer to cut the payment is the most common way an uninsured switch loses the 21 November 2024 exemption.

Shop the rate; do not stay because you think a switch will put you through the prescribed MQR. On a straight switch, it will not.

  • Stay: no prescribed MQR, no switch fees, but the incumbent offer is often posted-adjacent. Use competing holds as leverage.
  • Straight switch: prescribed MQR does not apply on the dates and conditions above. Budget discharge/assignment, appraisal, and legal — often a few hundred dollars, sometimes covered by the incoming lender's switch program. There is no IRD/prepayment penalty at maturity.
  • Refinance / break mid-term / take equity: always full MQR, plus penalty if you are not at maturity. Price that path on refinance break-even.
  • Process: 120-day rate holds, written confirmation that the new lender will treat the file as a straight switch (no discretionary MQR), then present the hold to the incumbent.
  • Underwriting still happens: credit, employment, and property due diligence can still decline a switch even when the prescribed MQR is off.

Model both contractual payments on the renewal calculator before you accept either letter.

Straight switch vs refinance is the first question If loan amount, remaining amortization, or payment schedule will increase, stop calling it a switch. The MQR is back on.

Ask the receiving lender's credit policy in writing OSFI's November 2024 letter leaves room for a lender to apply its own stressed ratios even when the prescribed MQR is not required.
