Does switching lenders at renewal require a new stress test in Canada?

Yes. Under OSFI B-20, switching to a new federally regulated lender at renewal requires qualification at the higher of your contract rate plus 2% or 5.25%. Renewing with your current lender does not require requalification.

How much does it cost to switch mortgage lenders at renewal in Canada?

Typical costs are $200–$400 discharge fee, $300–$500 legal fees (often covered by new lender), and $300–$500 appraisal for uninsured mortgages (often waived for insured). Many lenders offer $1,000–$3,000 cashback to cover these costs.

What is the difference between switching and refinancing a Canadian mortgage?

A switch at renewal moves the existing balance to a new lender without increasing the loan amount. A refinance changes the loan amount or structure and triggers prepayment penalties if done mid-term.

Should I use a mortgage broker to switch lenders at renewal?

Yes — brokers access wholesale rates from 15-20+ lenders not available at branches, typically charge no fee (paid by lender), and often find rates 0.1%–0.5% below what your existing lender offers.

What happens to CMHC insurance when I switch lenders at renewal?

CMHC insurance follows the mortgage when you switch at renewal. You do not pay a new premium — the existing policy transfers. This gives access to insured rate pricing and often means the appraisal is waived.

Renewal is the best time to switch lenders in Canada. Mid-term breaks trigger costly prepayment penalties — but at renewal, you are free to leave with minimal or no penalty. Switch costs at renewal are typically $500–$1,500 vs $5,000–$20,000+ mid-term.

Why switching at renewal is almost always low-cost:

No prepayment penalty — your term has ended; you are free to leave without penalty
Legal fees often covered — many lenders pay your legal fees ($300–$500) as part of a switch deal
Free appraisal — new lenders often waive the appraisal for switches (especially on insured mortgages)
Discharge fee only — your current lender charges $200–$400 to discharge the mortgage, not thousands
Unlike mid-term break — breaking a 5-year fixed mid-term can cost 3 months interest or IRD — potentially $10,000–$25,000

How you switch at renewal depends on whether your mortgage is insured (CMHC/Sagen/Canada Guaranty) or uninsured. Insured mortgages can typically switch more easily and often with no appraisal required.

Insured Mortgage (under 20% down originally)

Ease of switching:Easier to switch

Appraisal:Usually waived — CMHC insurance follows the mortgage

Stress test:Still required at new lender under OSFI B-20

Typical switch cost:$200 – $500 discharge + possible $0 legal (covered by new lender)

Rate access:Access to insured rate shelf — typically lower than uninsured rates

Uninsured Mortgage (20%+ down, or over $1M originally)

Ease of switching:Slightly more complex

Appraisal:New appraisal often required ($300–$500) — property value must support the loan

Stress test:Required at new lender

Typical switch cost:$200 – $500 discharge + $300–$500 appraisal + $300–$500 legal

Rate access:Uninsured rate shelf — typically 0.1% to 0.3% higher than insured

How to Use This Canadian Switch Mortgage at Renewal Calculator

Enter your remaining mortgage balance, your current lender's renewal offer rate, and the best rate from a new lender. Add your estimated switch costs (legal, appraisal, and discharge fees) to calculate your net saving over the new term. The calculator uses Canadian mortgage math with semi-annual compounding as required by the Interest Act.

What to Gather Before Using This Calculator

Your renewal statement from your current lender (shows balance and renewal offer rate)
Competing rate quotes from other lenders or a mortgage broker
Your discharge fee amount (usually $200–$400 — check your mortgage agreement)
Whether your mortgage is insured (CMHC, Sagen, or Canada Guaranty) — affects switch costs and appraisal requirements

The stress test tab shows whether you would qualify at the new lender under OSFI B-20 rules — switching lenders requires re-qualification even at renewal, unlike staying with your current lender.

The Formula

Canadian Mortgage Monthly Payment (semi-annual compounding):
Effective Monthly Rate = (1 + Annual Rate / 2)^(1/6) − 1
Monthly Payment = Balance × r × (1+r)^n / ((1+r)^n − 1)
where r = effective monthly rate, n = amortization months

Monthly Saving = Renewal Offer Monthly − New Lender Monthly

Saving Over Term = Monthly Saving × Term Months

Net Saving = Saving Over Term − Switch Costs + Cashback

Break-Even Months = Switch Costs ÷ Monthly Saving

OSFI B-20 Stress Test Qualifying Rate:
= MAX(Contract Rate + 2%, 5.25%)

Canadian mortgages use semi-annual compounding (not monthly), which is mandated by the Interest Act. This means the effective monthly rate is slightly lower than simply dividing the annual rate by 12, and the calculations in this calculator reflect that correctly.

Example

Maria — Switching at Renewal in Ontario

Maria has a $380,000 balance at renewal. Her bank offered 6.29% for a new 5-year fixed. A competing lender offered 5.79% with $800 in estimated switch costs and a $1,500 cashback bonus.

Remaining Balance	$380,000
Current Lender Renewal Offer	6.29% — $2,618/mo
Competing Lender Rate	5.79% — $2,504/mo
Monthly Saving	$114/mo
Switch Costs	$800
Cashback from New Lender	$1,500
Break-Even Point	7 months (before cashback)
5-Year Total Saving	$114 × 60 = $6,840
Net Saving (incl. cashback)	$6,840 + $1,500 − $800 = $7,540
Recommendation	Switch — saves $7,540 over 5 years

Before switching, Maria called her bank's retention team and showed them the competing offer. They improved their offer to 5.99% — still not matching, so Maria switched and saved $7,540 over the term.

Frequently Asked Questions

Yes. Under OSFI B-20 guidelines, when you switch to a new federally regulated lender at renewal, the new lender must qualify you at the higher of your contract rate plus 2%, or 5.25%. This is the same stress test used for new mortgages. However, if you renew with your current lender — even at a new rate and term — they are not required to requalify you, which is a significant advantage of staying with your existing lender if your financial situation has changed.

Switching at renewal is much cheaper than breaking a mortgage mid-term. Typical costs are a discharge fee of $200–$400 from your current lender, legal or title transfer fees of $300–$500 (often covered by the new lender as a switch incentive), and an appraisal of $300–$500 for uninsured mortgages (often waived for insured mortgages). Many lenders offer cashback of $1,000–$3,000 to cover these costs, making the net out-of-pocket cost zero or very low.

A switch (at renewal) means moving your existing mortgage balance to a new lender at the same amortization and term structure, without increasing the loan amount. A refinance means changing the loan amount — either increasing it to access equity or restructuring the amortization. Refinancing mid-term triggers prepayment penalties and requires full re-qualification. Switching at renewal involves no penalty, lower costs, and a simpler process since no new money is being borrowed.

Using a broker at renewal is often valuable because brokers have access to wholesale rates from multiple lenders that are not available directly from bank branches. Brokers typically charge no fee to you — they are paid by the lender. A good broker will shop your renewal to 15–20+ lenders simultaneously and often find rates 0.1% to 0.5% below what your existing lender offers. The time investment is minimal and the potential saving over a 5-year term can be $5,000–$15,000 on a $400,000 mortgage.

If your mortgage is insured (backed by CMHC, Sagen, or Canada Guaranty), the insurance follows the mortgage when you switch lenders at renewal. You do not pay a new CMHC premium on the switch — the existing insurance policy transfers. This is a significant benefit of insured mortgages: they give you access to insured rate pricing (which is typically 0.1%–0.3% lower than uninsured rates) and the appraisal is often waived because the insurer already holds the risk on the property.
