Porting a Mortgage in Ontario: Can You Take It to Your Next Home?

You’re ready for a different home. Maybe you need another bedroom, want a shorter commute, or are planning to downsize.

Your mortgage, however, still has time left on its term.

Before building your moving budget, find out whether you can take your existing mortgage arrangement to the next property. This is commonly called porting a mortgage.

What does porting a mortgage mean?

Porting allows an eligible mortgage’s balance, interest rate, and terms to transfer to a new property. Availability and restrictions depend on your lender and mortgage contract.

It may help you preserve favourable mortgage features or avoid a penalty for breaking the contract early. However, buying a less expensive home or needing additional borrowing can change the calculation. Source: Financial Consumer Agency of Canada.

For Ontario homeowners, the practical first step is to request the details of your own mortgage’s portability feature.

Does a portable mortgage mean automatic approval?

No. A portability feature does not guarantee that your planned move will qualify.

Borrowers generally need to qualify again under the applicable lender requirements.

Confirm this before relying on a port to finance your purchase. Source: BCFSA’s portability guidance.

Give your mortgage professional a current picture of your finances. If your income, debts, employment, or household circumstances have changed since your original application, bring those changes into the conversation immediately.

A useful question is: “What needs to be approved before I can rely on this option?”

What if your next home requires a bigger mortgage?

Consider a hypothetical homeowner moving from Hamilton to Burlington.

They owe $350,000 on their current home and estimate that they’ll need a $500,000 mortgage for the next purchase. The question is now larger than whether the existing mortgage can move.

They also need a clear proposal for the additional $150,000.

Ask the lender to show:

• How the additional borrowing would be priced.

• The resulting mortgage payment.

• The term and repayment schedule.

• All applicable fees and conditions.

• What happens to the existing mortgage terms.

  
  

Use the written proposal when comparing options. Looking only at the rate on the original balance won’t show the full cost of the new arrangement.

Check the sale and purchase dates early

Put both expected closing dates in front of your lender before treating the financing as settled.

Ask whether the dates fit its porting requirements, what happens if either transaction is delayed, and whether money will be needed temporarily between the two closings.

Make the timing questions concrete: “Our sale is expected to close on this date, and our purchase on that date. How would the financing work?”

That is easier to assess than a general question about moving sometime this year.

How should you compare porting with a new mortgage?

Request two written scenarios for the same planned purchase: the proposed port and an available replacement mortgage.

Compare the same borrowing amount and repayment period wherever possible. Include payments, upfront costs, any early payout charge, and the features you expect to use.

Then bring your next few years into the decision. Are you likely to move again? Do you expect to make extra payments? How much flexibility matters to your household?

The strongest comparison connects the numbers to those plans.

Frequently asked questions

Can I port my mortgage to any property?

Don’t assume so. Ask the lender to assess the specific property you intend to purchase.

What if I am downsizing?

Request a written calculation showing how a smaller mortgage would affect the transaction, including any applicable charges.

What should I bring to the first conversation?

Start with your mortgage statement, contract, expected sale price, target purchase budget, and proposed closing dates.
