Mortgage Porting in Canada
Explore mortgage porting options in Canada with Mortgage Advisor Canada. Learn how porting works, when it makes sense, and how it compares with breaking or switching your mortgage.
Mortgage Porting in Canada
Keep the mortgage you like while moving to a new home — but make sure porting really beats your other options.
Mortgage porting allows some borrowers to move their current mortgage from one property to another with the same lender instead of breaking the mortgage and starting over from scratch.
At Mortgage Advisor Canada, we help clients across BC and Ontario understand whether porting a mortgage is the right move when buying a new home. Some borrowers want to preserve a lower rate. Others want to avoid a costly prepayment penalty or keep favorable mortgage features that may no longer be available in the market.
A strong mortgage porting decision is not just about avoiding penalties. It is about comparing the true cost of porting against breaking the mortgage, switching lenders later, or setting up a new mortgage entirely. FCAC says portability lets you transfer your mortgage balance, interest rate, and terms and conditions to a new property, and may be worth considering if your current mortgage has favorable features or if you want to avoid prepayment penalties for breaking the contract early.
What Is Mortgage Porting?
Mortgage porting means taking your existing mortgage and moving it from your current home to a new property, usually when you sell one home and buy another.
FCAC describes portability as the transfer of your mortgage balance, interest rate, and terms and conditions to a new property.
That usually means:
-
the lender stays the same
-
the property changes
-
you are trying to preserve your current mortgage contract features as much as possible
-
you are moving before the mortgage term ends
Borrowers often search:
-
port your mortgage
-
port mortgage
-
mortgage portability
-
portable mortgage canada
-
transferring mortgage to new property
But the core question is usually the same: can I keep my current mortgage when I move homes instead of breaking it?
Mortgage Porting vs Mortgage Switch
Mortgage Porting
Porting means moving your mortgage to a new property with the same lender.
Mortgage Switch
A mortgage switch means moving your mortgage to a new lender, usually at renewal, often while keeping the same property.
FCAC’s guidance supports this distinction in two different places.
FCAC’s mortgage-choice guidance explains portability as moving your mortgage to a new property, while FCAC’s transfer-products guidance says you cannot transfer your existing mortgage to another lender as a simple product transfer.
So:
-
porting = same lender, new property
-
switching = new lender, usually same property at renewal
This is why your site should keep Mortgage Porting and Mortgage Switch / Transfer as separate pages.
Why Borrowers Port a Mortgage
Borrowers usually consider porting a mortgage because they are moving homes before the end of their current term and want to avoid losing a favorable mortgage.
Common reasons include:
-
preserving a lower rate
-
avoiding a prepayment penalty
-
keeping favorable mortgage features
-
avoiding the cost or hassle of setting up an entirely new mortgage
-
reducing disruption while moving homes
FCAC says you may consider porting your mortgage if your existing mortgage offers favorable features or if you want to avoid prepayment penalties for breaking your mortgage contract early.
This is the core use case: you like your current mortgage enough that it may be worth trying to take it with you.
How Mortgage Porting Works
A ported mortgage generally applies your current mortgage contract to a new home, but it is not automatic and it is not guaranteed.
In practice, porting usually involves:
-
notifying your current lender that you are selling and buying
-
checking whether your mortgage is actually portable
-
confirming the lender’s timing rules
-
re-qualifying with the lender for the new property and your current finances
-
determining whether the mortgage amount will stay the same, increase, or decrease
FCAC says you should check with your lender to see if your mortgage is eligible for porting and ask what restrictions apply. FCAC also says that if your new home costs less than the amount of your mortgage, you may pay a prepayment penalty, and if you need to borrow more money for your new home, you should ask your lender for details.
That matters because not every mortgage has portability, and even when it does, the lender may impose conditions.
Do You Have to Requalify to Port a Mortgage?
In many cases, yes.
Porting is not just a mechanical transfer of the loan from one property to another. The lender will usually want to confirm that the new property and your current financial position still fit its approval rules.
FCAC does not publish a blanket national rule that says every single port requires requalification, but it does say borrowers must check with their lender to confirm eligibility and restrictions. That is the safest official framing.
In practical terms, lenders often review:
-
income
-
debts
-
credit
-
the new property
-
the amount of financing needed
-
whether the move is a straight port, a port and increase, or a port and decrease
This is one of the most important page enhancements because many borrowers assume porting is automatic. It usually is not.
Types of Mortgage Porting
Not every port looks the same.
Straight Port
A straight port is the cleanest version. You move the existing mortgage balance, rate, and terms to the new property with the same lender, without materially changing the amount.
Port and Increase
A port and increase usually means the new home costs more, so you keep the existing mortgage and add new borrowing. That additional borrowing may be priced separately or blended, depending on the lender.
Port and Decrease
A port and decrease usually means the new home is less expensive, so the mortgage amount must come down. Depending on the lender and contract, this may trigger a partial penalty.
FCAC’s portability guidance supports this general structure because it says that if your new home costs less than your mortgage amount, you may face a prepayment penalty, and if you need more money for the new home, you should ask your lender for the details.
CMHC also recognizes two insurance-portability structures for insured mortgages:
-
straight portability
-
portability-with-increase.
What Is CMHC Portability?
For borrowers with CMHC-insured mortgages, there is also a separate insurance concept called CMHC Portability.
CMHC says portability allows clients to transfer their existing mortgage loan insurance to a new property, which can help avoid the need for new coverage and save associated costs.
CMHC describes two options:
-
straight portability, where no additional premium is required
-
portability-with-increase, where additional premium may be required, though premium credits may be available.
CMHC says that for straight portability:
-
the new amortization cannot exceed the remaining amortization, subject to program maximums
-
the new loan-to-value must be equal to or less than the current LTV
-
the new loan amount must be equal to or less than the current outstanding balance.
This matters because mortgage porting and mortgage-insurance portability are related, but not identical. For some insured borrowers, both layers matter.
When Porting a Mortgage May Be the Right Move
Porting a mortgage may make sense when:
-
your current mortgage rate is favorable
-
breaking the mortgage would trigger a costly penalty
-
your current mortgage has good features you want to keep
-
your lender allows portability on workable terms
-
the timeline between selling and buying fits the lender’s rules
-
the total economics of porting are better than replacing the mortgage
FCAC’s break-your-mortgage guidance says one reason borrowers break a mortgage is that they want to buy a new home and move, but it also warns that prepayment penalties on closed mortgages can cost thousands of dollars. That is exactly why porting can matter.
Porting is often strongest when your current mortgage is genuinely better than what you could replace it with today.
When Porting a Mortgage May Not Be the Best Option
Porting is not automatically the right answer.
It may be a weaker fit when:
-
current market rates are actually better than your existing mortgage
-
your current mortgage has weak features or restrictions
-
the lender’s porting conditions are too rigid
-
the timeline between sale and purchase does not fit the lender’s rules
-
the new financing need is large enough that a full rework may be better
-
the total cost of porting is not clearly better than breaking and replacing the mortgage
FCAC’s break-your-mortgage guidance says borrowers should compare the costs and benefits of breaking the mortgage contract against other options. That same logic applies to porting: do the math instead of assuming portability wins automatically.
Mortgage Porting vs Breaking the Mortgage
This is one of the highest-intent comparisons on the page.
Porting
You try to carry your current mortgage forward to the new property with the same lender.
Breaking the Mortgage
You end the current mortgage contract early and set up a new mortgage arrangement.
FCAC says that if you break a closed mortgage, you normally pay a prepayment penalty, and that the cost can be thousands of dollars.
FCAC also says borrowers may break a mortgage if they want to buy a new home and move.
So the right comparison is:
-
what is the penalty to break?
-
what is the value of keeping the current rate and features?
-
what would a new mortgage cost instead?
-
what fees come with either option?
Porting can be attractive because it may avoid or reduce the need to break a favorable mortgage early, but the total math still matters.
Mortgage Porting vs Mortgage Refinance
A mortgage port and a mortgage refinance are not the same thing.
Mortgage Porting
You are trying to preserve your current mortgage contract while moving to a new property with the same lender.
Mortgage Refinance
You are restructuring the mortgage more substantially, often by changing the amount borrowed, accessing equity, or replacing the mortgage more broadly.
Porting may be the better fit when:
-
you want to keep your current lender
-
your current rate is attractive
-
you want to minimize disruption
-
the lender’s portability rules work in your situation
A refinance may be the better fit when:
-
you need a bigger structural change
-
you want a different lender
-
you want to access equity
-
your current mortgage is no longer competitive enough to preserve
FCAC’s portability and break-your-mortgage guidance supports this separation because portability is framed as preserving the existing mortgage on a new property, while breaking and renegotiating is a separate path.
What Costs Can Come With Mortgage Porting?
Porting is often used to avoid a prepayment penalty, but that does not mean the move is cost-free.
Potential costs can include:
-
appraisal fees
-
legal fees
-
administrative fees
-
fees tied to new borrowing if you need more money
-
partial penalties in some port-and-decrease situations
-
blended or top-up pricing on added funds
FCAC says borrowers should check with their lender to see whether the mortgage is portable and what restrictions apply. FCAC also says that if the new home costs less than the current mortgage amount, a prepayment penalty may apply, and if more money is needed for the new home, the borrower should ask the lender for details.
So the right question is not just “Can I port?” It is “What will porting actually cost, and is it still the best option?”
Do Lenders Set Time Limits for Porting?
Usually, yes.
Your Google data strongly suggests that many lenders use windows like 30, 60, 90, or 120 days. But the safer official framing is that timing rules are lender-specific.
FCAC does not publish one universal national timeline for mortgage porting. Instead, it says borrowers should ask the lender whether the mortgage is portable and what restrictions apply.
That means these are key questions to ask early:
-
how long can you be between selling and buying?
-
what happens if one closing date moves?
-
what documents does the lender require?
-
when must the new approval be finalized?
Because those rules vary, borrowers should not rely on generic internet timelines without confirming the actual lender policy.

Mortgage Porting in Toronto and Vancouver
In larger, higher-balance markets, mortgage porting can matter even more because the penalty to break a favorable mortgage may be more meaningful and the value of preserving a good contract can be larger.
Toronto Mortgage Porting
In Toronto, porting may be especially relevant for borrowers moving within the GTA who want to preserve a favorable mortgage while changing homes.
Vancouver Mortgage Porting
In Vancouver, mortgage porting may be worth analyzing carefully when home values, financing gaps, and blended borrowing needs make the decision more complex.
This is why city-specific porting pages may eventually make sense, but the main porting page should own the broad national intent first.
Common Questions About Mortgage Porting
Mortgage porting means transferring your mortgage balance, interest rate, and terms and conditions to a new property with the same lender. FCAC describes portability in exactly those terms.
No. Porting means keeping the same lender and moving to a new property. Switching means moving to a new lender, usually at renewal. FCAC’s portability and transfer-products guidance supports that distinction.
No, not as a true port. FCAC says you cannot transfer your existing mortgage to another lender as a simple product transfer. Porting is generally about keeping the same lender.
Common reasons include preserving a favorable rate, avoiding a prepayment penalty, and keeping mortgage features you like. FCAC says those are key reasons borrowers consider portability.
Often that is one of the main reasons borrowers consider it. FCAC says portability may be useful if you want to avoid prepayment penalties for breaking your mortgage contract early.
Sometimes. FCAC says if you need to borrow more money for your new home, you should ask your lender for details.
FCAC says you may pay a prepayment penalty if your new home costs less than the amount of your mortgage.
Yes. FCAC says to check with your lender to see if your mortgage is eligible for porting and ask about any restrictions that apply.
CMHC portability allows eligible borrowers to transfer existing CMHC mortgage loan insurance to a new property. CMHC says this may avoid the need for new coverage and may reduce associated costs.
