What a mortgage switch is
A mortgage switch—also called a transfer—is the replacement of an existing mortgage with a mortgage from a new lender, normally around maturity, without accessing equity or materially restructuring the debt.
The borrower does not literally assign the old contract unchanged to the new lender. The new lender approves a new mortgage, and the registered security is transferred, assigned, discharged or replaced through the appropriate legal process.
A straightforward switch usually involves:
The same property
Approximately the same unpaid balance
No equity takeout
No debt consolidation
The same remaining contractual amortization
No major ownership restructuring
A switch remains subject to the new lender’s borrower, property and documentation review.
Renewal, straight switch and refinance compared
| Feature | Current-lender renewal | Straight switch | Refinance |
|---|---|---|---|
| Lender | Existing lender | New lender | Existing or new lender |
| Balance | Normally remaining balance | Normally remaining balance, subject to limited permitted costs | May increase or decrease |
| Equity takeout | No, unless separately restructured | No | Yes, where eligible |
| Debt consolidation | Not part of a simple renewal | Not permitted in a straight switch | Common refinance purpose |
| Amortization | May continue or be renegotiated | Remaining contractual amortization generally maintained for straight-switch relief | May be changed subject to policy |
| New underwriting | Often limited, but lender-specific | Yes | Yes |
| Stress-test treatment | Existing lender renewal generally does not involve a new prescribed MQR test | Special relief may apply where all conditions are met | Normal current qualification rules apply |
| Property review | May be limited | New lender may require valuation or appraisal | New valuation normally required |
| Legal registration | Usually no change of lender registration | Transfer, assignment or discharge and new registration may be required | Discharge and new or amended registration commonly required |
| Primary objective | Continue the mortgage | Obtain better terms without increasing debt | Change the financing structure |
Current straight-switch stress-test treatment
Two related federal measures must be distinguished.
Subsection — OSFI treatment for uninsured straight switches
Effective November 21, 2024, OSFI stopped prescribing the minimum qualifying rate for an eligible uninsured straight switch where:
The existing mortgage is a stand-alone, amortizing, non-readvanceable uninsured mortgage
The mortgage moves from one federally regulated financial institution to another
The remaining contractual amortization does not increase
The loan amount does not increase, other than up to $3,000 for permitted transaction costs
No equity is taken out
The new lender must still follow sound underwriting under Guideline B-20 and may apply its own qualifying rate, credit standards and risk policy. The change removed OSFI’s prescribed MQR requirement; it did not create automatic approval.
Classification: OSFI prudential guidance for federally regulated financial institutions.
Effective date: November 21, 2024.
Current prescribed MQR for other uninsured originations as of January 29, 2026: greater of contract rate plus 2% or 5.25%.
Material qualification: Straight-switch relief is limited to qualifying transactions.
Subsection — Federal mortgage-insurance treatment for low-ratio switches
Effective for qualifying mortgage-insurance applications submitted on or after December 16, 2024, federal mortgage-insurance rules allow certain low-ratio mortgages to switch from a federally regulated lender to a new lender without the minimum qualifying rate, where:
The original mortgage was from a federally regulated institution
It was previously assessed using the MQR
The contractual amortization schedule is maintained
No equity is taken out
The unpaid principal may rise by no more than $3,000 for permitted transaction costs
All other government-backed mortgage-insurance conditions are satisfied
This insurance mechanism aligns low-ratio switch treatment more closely with the OSFI straight-switch relief and can apply when moving to a new lender outside the original federally regulated institution, subject to insurer acceptance.
Classification: Federal mortgage-insurance policy.
Source: Department of Finance Canada.
Effective date: December 16, 2024.
Material qualification: Availability depends on lender participation, insurer approval and all continuing insurance criteria.
What the relief does not mean
The borrower may still have to establish:
Satisfactory mortgage-payment history
Acceptable credit
Current income or other supportable repayment capacity
Acceptable property
Adequate property insurance
Clear title
Acceptable remaining amortization
Compliance with the new lender’s policy
A lender may also use an internal qualifying rate even where the OSFI-prescribed MQR does not apply.
The rule therefore increases the opportunity to shop at renewal; it does not force a lender to accept the borrower.
Insured and insurable switches
Subsection — Existing insured mortgage
An existing insured mortgage may be transferred to another lender while preserving the insurance, subject to lender and insurer rules.
The borrower should provide:
Insurance certificate number
Existing mortgage details
Original amortization
Current balance
Property and borrower information requested by the new lender
FCAC notes that providing the existing certificate may help avoid paying the mortgage-insurance premium twice. A balance increase or amortization extension may trigger a new premium, premium surcharge or loss of transfer treatment.
Subsection — Low-ratio insurable mortgage
A mortgage with 20% or more equity may be “insurable” under a lender’s funding program even though the borrower did not originally pay a high-ratio premium.
Whether a new lender can insure or transfer it depends on:
Original mortgage and property eligibility
Original purchase price
Amortization
Occupancy
Transaction purpose
Prior stress-test treatment
Insurer and lender policy
“Low ratio” does not automatically mean “insurable.”
Costs of changing lenders
A switch around maturity usually avoids an ordinary prepayment penalty because the existing term is ending. FCAC confirms that a borrower can make a full payment at term end without the ordinary early-prepayment penalty.
Other expenses may remain:
Discharge or assignment fee
Registration fee
Legal fee
Title insurance
Appraisal
Administration fee
Provincial registration expenses
Some lenders reimburse part or all of eligible switch costs as a promotional or product-specific incentive. FCAC recommends confirming both the total costs and whether the new lender will cover any portion.
Classification: Federal consumer guidance and lender-specific incentives.
Material qualification: Cost reimbursement is not universal and may be subject to clawbacks if the mortgage is discharged early.
Collateral-charge complications
A collateral charge can secure more than the stand-alone mortgage balance. It may also secure:
HELOC
Personal line of credit
Credit card
Car loan
Other credit provided by the same institution
To move the mortgage, the borrower may have to repay or transfer every debt secured by the charge. The charge may need to be discharged and replaced rather than transferred through a simple assignment.
FCAC advises borrowers with collateral charges to begin several months before maturity and confirm which debts must be repaid to remove the existing security.
A mortgage balance may appear transferable while an attached HELOC or other secured obligation prevents the collateral charge from being released.
Appraisals and property acceptance
A new lender may:
Accept an automated valuation
Rely on available insurer information
Require a full appraisal
Apply a lower accepted value
Decline a property outside its policy
A straight switch does not eliminate property underwriting. It only limits the changes being made to the mortgage.
Portability is different from switching
Portability normally means taking an existing lender’s mortgage terms to a different property.
Switching means moving the mortgage on the same property to another lender.
A portable mortgage still requires:
Approval of the new property
Requalification
Closing-date coordination
Treatment of additional funds
Compliance with lender timelines
Porting can avoid a break penalty in some circumstances, but it does not make another lender part of the transaction.
When a proposed switch becomes a refinance
An intended switch will commonly require refinance treatment where the borrower wants to:
Increase the balance beyond permitted transaction costs
Access equity
Consolidate credit cards or loans
Pay out a HELOC not included in permitted transfer treatment
Extend amortization beyond the permitted remaining schedule
Add or remove a borrower
Change ownership
Convert a readvanceable plan into a materially different structure
Change the registered security beyond what the transfer program permits
The exact classification depends on the lender, insurer, title structure and purpose.
The borrower asks for a switch but needs a refinance
In HopeWell’s anonymized files, homeowners frequently begin with a request to “move the mortgage for a better rate.” During review, the actual objectives may include:
Paying credit-card debt
Increasing the mortgage
Removing a second mortgage
Extending amortization
Accessing renovation funds
Adding or removing an owner
Once one of these objectives is introduced, the analysis is no longer simply about transfer pricing. It must address current value, total secured debt, qualification, legal registration and whether increasing the mortgage is suitable.
The recurring lesson is:
A switch changes the lender. A refinance changes the financing.
If You Remember Only Three Things
Straight-switch stress-test relief applies only when the transaction satisfies specific federal conditions.
A new lender still approves the borrower and property under its own policy.
Increasing the balance, extending amortization or consolidating debt can turn a switch into a refinance.
