Porting a mortgage lets homeowners transfer their existing mortgage terms to a new property, helping them avoid penalties associated with breaking a mortgage contract early and the hassle of obtaining a new one. While there are many factors to consider, here’s everything you need to know about porting your mortgage and why it may not be the best move for everyone.
What is porting a mortgage?
Porting a mortgage (also known as a mortgage port) means transferring your current mortgage contract—including its interest rate, remaining balance, and term from your original mortgage—to a new property with the same lender. Simply put, portable mortgages allow you to sell your existing home and complete a home purchase of another property without breaking your mortgage agreement.
How does porting a mortgage work?
When porting, your lender transfers your existing mortgage balance to a new property. As mentioned, this includes your existing interest rate, remaining term, amortization, and other terms and conditions without penalty.
However, you may need additional funds if the new home’s price exceeds your current mortgage amount. In this case, you can consider a home equity loan or a blend-and-increase approach, combining your existing interest rate with the current rate to create a weighted average for the extra borrowing.
Can all mortgages be ported?
No, not all mortgages can be ported. While it is a common strategy in the mortgage industry, mortgage porting will depend on your mortgage type, mortgage term, and lender. Most fixed-rate mortgages are portable unless you have a restricted mortgage, which may limit your ability to transfer the mortgage when buying or selling property. Conversely, variable-rate mortgages are rarely portable.
The mortgage term can also impact your ability to port a mortgage, as some lenders only allow portability within certain periods of the term or may impose penalties if you try to port near the end of your mortgage term.
If you are relocating to a new province, you may be unable to port your mortgage if your lender does not operate there. Always review your mortgage agreement or consult a mortgage broker to confirm eligibility.
Mortgage porting example
Let’s assume you have a $450,000 balance remaining on your mortgage, a fixed rate of 3% (secured in 2022), and are three years into a $500,000 mortgage with a five-year term (two years remaining). But life happens, and now you’re considering relocating to another part of the city.
If you’re selling your current property and planning to move to another property, you can choose a straight port. This means transferring your mortgage to a new property of equal or lesser value, keeping the original 3% rate (compared to 2025’s market rate of 5%), and avoiding breaking your mortgage. In contrast, refinancing the full amount at today’s 5% rate would result in a higher monthly payment.
Types of porting a mortgage
Depending on your mortgage lender and your situation, you may be eligible for the following mortgage options:
- Straight port: Transfer your existing mortgage balance and terms to a property of equal or lesser value. No changes to your rate or term occur, making this the simplest option. This can be especially beneficial if you have a fixed-rate mortgage with lower rates than currently available.
- Port and increase: Borrow extra funds for a more expensive home. The new mortgage combines your original rate (on the existing balance) and current rates (on the additional amount). It’s important to consider all costs associated with porting to a more expensive home, including appraisal fees, potential prepayment penalties on the increased amount, and any bridge financing that may be required to coordinate the sale of your old property and purchase your new one.
- Port and decrease: If the principal amount on the new property is less than the remaining principal balance, prepayment charges may be triggered. This is because lowering your mortgage balance during downsizing counts as an early partial repayment of your loan, which lenders penalize to recover lost interest income. However, some lenders may waive or reimburse part of the prepayment charge.
When does porting a mortgage make sense?
At its core, if it saves you money and you can afford the new mortgage payments on the new property, porting a mortgage is generally a good idea. Porting makes the most sense when your existing mortgage rate is significantly lower than current market rates, allowing you to retain a favourable fixed rate in a rising interest rate environment.
| Pros of porting a mortgage | Cons of porting a mortgage |
| Porting lets you avoid prepayment penalties by transferring your existing mortgage terms instead of breaking the contract early. | Porting requires navigating tight timelines, often forcing you to sell and buy within 30–120 days, which can be straining. |
| It allows you to lock in low interest rates if your original rate is below current market levels, helping you secure the best mortgage rates available. | It limits flexibility by locking you with your current lender, even if competitors offer better rates or terms for your new property. |
| The process simplifies transactions by aligning the sale of your current home with the purchase of a new property without resetting your amortization schedule. |
In some cases, the total costs of porting may outweigh the benefits, making it more cost-effective to break your mortgage and pay the prepayment penalties instead. Consulting a mortgage broker can help you compare your options and choose the best path forward for your financial goals.
Alternatives to porting a mortgage in Canada
Breaking your mortgage
Pay a prepayment penalty (usually 3 months’ interest for variable rates or interest rate differential for fixed) to discharge your mortgage early. It is viable if current mortgage rates are significantly lower than your existing rate.
Borrowers relocating unexpectedly or leveraging significant equity gains may explore this route, though careful examination is essential.
Blend and extend
With blend-and-extend mortgages, you combine your existing mortgage rate with current market rates into a new blended rate. This option also extends the repayment period to reduce your monthly payments further. However, this stretches interest payments over a longer period, increasing total interest costs.
Cash-out refinance
Cash-out refinancing enables homeowners to tap into their accumulated home equity by refinancing their total mortgage loan at current interest rates. This process increases the size of your existing loan with your lender, allowing you to withdraw the difference between your previous mortgage balance and the new, larger loan amount as cash.
This is an effective way to quickly access funds using your home equity and can be particularly beneficial in emergency situations such as unexpected medical expenses, urgent home repairs, or consolidating high-interest debt.

Frequently asked questions
Is there a penalty for porting a mortgage?
Typically, no—unless you reduce your mortgage balance (port and decrease). Prepayment charges might then apply to the paid-off amount. When considering mortgage porting, it’s essential to work closely with your lender to understand the process and any potential costs involved.
Do you need a down payment when porting a mortgage?
Yes, if your new home costs more than your current mortgage balance, you can use the proceeds from your sale or savings to cover the difference.
How to port a mortgage in Canada?
Porting a mortgage involves notifying your lender about selling your current home and buying a new one, requalifying based on the new property’s value and financial status and finalizing the transfer once approved. This preserves your existing rate for the original loan amount.
