Moving does not always mean you need to break your current mortgage. If your mortgage is portable, your lender may allow you to transfer some or all of your existing mortgage terms to a new property when you sell your current home and buy another one.
Mortgage portability can be helpful when your existing mortgage rate and term are attractive, especially if you are moving before your renewal date. It is not automatic, though. Your lender will usually need to approve the new property, review your updated financial situation, and confirm that you meet its portability rules and timing requirements.
Quick answer: A mortgage port may help you preserve your existing rate and avoid or reduce a mortgage prepayment penalty, but the lender must approve the new property and your updated application. The best choice depends on your current mortgage terms, the amount you need to borrow, the new property, your income, and the total cost of each option.
Ask About Porting Your Mortgage
Portability may be worth reviewing if you are an Ontario homeowner who is selling and buying another property before your current mortgage term ends. It is often most useful for borrowers who have a favourable fixed rate, expect to move within the lender’s required timing window, and want to avoid paying a potentially significant penalty to break their mortgage early.
A port may be considered when you are:
When your current home is sold, the existing mortgage is normally discharged from that property’s title. If the lender approves the port, a new mortgage is registered against the property you are buying. The lender may transfer some of the original mortgage terms, such as the remaining term and interest rate, subject to the mortgage contract and its current underwriting requirements.
Most lenders require you to submit a new application or updated documentation. Even though you are already a client, the lender still needs to assess the new property, confirm the mortgage amount, and review whether your income, credit, debts, and down payment still meet its guidelines.
A straight port generally means the mortgage amount on the new property is the same as, or close to, the mortgage balance being transferred from the existing property. This can be the simplest portability scenario, but approval is still required.
A port and increase applies when you need more mortgage financing for the new property than the balance remaining on your current mortgage. The existing balance may be ported, while the additional funds are advanced at a new rate or under a blended-rate structure, depending on the lender and mortgage product.
This is common when moving to a larger home, buying in a higher-priced area, or purchasing a property with a larger mortgage requirement. The added amount will normally be fully requalified under the lender’s current rules.
A port and decrease applies when the mortgage required on the new property is lower than the balance on your current mortgage. Depending on your mortgage contract, the lender may allow the smaller mortgage to be ported, but a prepayment charge could still apply to the portion being paid down. This is especially important to review when downsizing.
Mortgage portability is lender-specific. A lender may approve one move and decline another based on the new property, the amount required, or changes in your financial profile. Before you rely on a port as part of your purchase plan, it is important to confirm the exact terms in writing.
Lenders commonly review:
Porting can be useful, but it is not automatically the lowest-cost or best long-term choice. A mortgage should be reviewed as part of the full move, not just as a way to preserve a rate.
Important: Do not assume your mortgage is portable simply because another lender offers portability on a similar product. The wording in your own mortgage commitment and contract controls, and lender rules can vary by product and situation.
Start the conversation as early as possible, ideally before making an unconditional offer on your next home. A portability review can take time because it may involve your existing lender, a new application, a property review, and coordination with your purchase and sale dates.
You may be asked to provide:
Porting is only one option. Depending on your mortgage balance, the size of your move, your future plans, and the penalty to break your current mortgage, it may make more sense to compare a port against a new mortgage with another lender, an early renewal, or a refinance structure.
A full review should compare the total picture: mortgage penalty, interest rate, payment, added borrowing costs, lender fees, flexibility, prepayment privileges, portability terms, and how long you expect to keep the next property.
Related mortgage decisions may include reviewing your mortgage renewal options or considering whether a mortgage refinance better supports your new plans.
It may avoid or reduce the prepayment charge on the mortgage amount that is successfully transferred, but it does not guarantee that every cost disappears. A penalty may still apply when the mortgage amount is reduced, the lender’s timing rules are not met, or the port cannot be completed under the mortgage contract.
Usually, yes. The lender may need to reassess your income, debts, credit, down payment, and the new property. A port is not the same as automatically moving your old mortgage from one address to another.
No. The new property must meet the lender’s underwriting and property guidelines. Factors such as property type, condition, location, condo status, marketability, and loan-to-value ratio can affect the lender’s decision.
You may need a port and increase. Your existing mortgage balance may be transferred while the additional funds are reviewed and priced under the lender’s current rules. The result may involve a blended rate, a new rate on the added funds, or separate mortgage portions.
Not necessarily. A low rate is important, but it is only one part of the decision. Compare the port with the total cost, mortgage features, flexibility, penalties, and your plans for the next few years before choosing a direction.
Before you rely on portability in your purchase plan, review the terms of your current mortgage and compare the cost of porting with your other available options. A clear review before you buy can help prevent surprises around penalties, qualification, timing, and added borrowing.

Mortgage portability, qualification, rates, penalties, and lender policies vary by mortgage contract, lender, property, and individual financial situation. A review of your specific mortgage documents is needed before making a decision.
