Thinking about moving up in Innisfil but worried about losing your current mortgage rate? You are not alone. When you have a good rate, the idea of starting fresh at today’s rates can feel daunting. The good news is that many lenders let you “port” your mortgage, which can help you keep your rate and term when you buy your next home.
In this guide, you’ll learn what mortgage portability means, how it works in practice, common move-up scenarios in Innisfil, and the key questions to ask your lender. You’ll also get a simple checklist to plan your move with fewer surprises. Let’s dive in.
What mortgage portability means
Mortgage portability lets you transfer your existing mortgage rate, remaining balance, and remaining term from your current home to a new one. You avoid breaking your mortgage and paying a break penalty, and you keep any favorable rate you negotiated earlier.
For move-up buyers in Innisfil, this can be valuable if your current rate is lower than what is available today. It can also help you manage timing if you can coordinate your sale and purchase within your lender’s porting window.
How porting works
Your main options
- Full port: Move your entire outstanding mortgage, rate, and remaining term to the new property.
- Partial port plus top-up: Port part or all of your current balance, then borrow any extra you need as a new amount at your lender’s current pricing. Some lenders offer a blended rate, while others price the new portion separately.
- No port: Break your mortgage and take a brand-new one. This usually triggers a break penalty and may or may not be the best overall cost once you factor in rates, fees, and timing.
Lender approval and rules you should expect
- Approval is required. Your lender will ask for details on the new property and updated borrower information.
- Same borrowers. Many lenders want the same people on the mortgage. Adding or removing a borrower can push you into a refinance.
- Owner-occupied use. Portability typically applies when you move to another owner-occupied home. Some property types face restrictions.
- Appraisal. Expect an appraisal or valuation of the new property before approval.
- Top-up handling. If you need more money, lenders may price it at current rates or blend it with your existing rate. Approaches vary by lender.
Timelines and coordinating closings
Lenders set strict windows for when a port is allowed around your sale and purchase dates. These windows often span weeks to a few months, but exact timelines vary by product and lender. If your sale and purchase do not close on the same day, you may need bridge financing to cover the gap. Start the process early so your approval, appraisal, and legal paperwork are ready.
Costs, penalties, and other fees
Porting is designed to help you avoid a break penalty. If you break instead of porting, penalties are calculated according to your mortgage contract. For fixed-rate mortgages, lenders often use an Interest Rate Differential method, while variable-rate mortgages commonly use a few months of interest. The Financial Consumer Agency of Canada explains how penalties and switching work in plain language, which can help you compare options. You can review their guidance in the FCAC’s mortgage resources page at the Financial Consumer Agency of Canada.
Other costs can include appraisal fees, discharge and registration fees, legal fees, and Ontario land transfer tax on your purchase. Plan for these when comparing a port to a new mortgage.
Requalification and insurance rules
Stress test and underwriting
Most lenders will re-qualify you when you port. That means updated income verification, credit review, and debt-service calculations under the current qualifying rules. For background on Canada’s prudential framework and stress testing, visit the Office of the Superintendent of Financial Institutions.
Rate context also matters. You can review the broad interest rate backdrop at the Bank of Canada to understand how today’s rates compare with the rate you hold now.
If your mortgage is insured
If your current mortgage is insured by CMHC or a private insurer, portability often requires insurer approval. The loan-to-value on the new home will be reviewed, and if you need a larger loan that exceeds insurer limits, you may need a bigger down payment or a different approach. For high-level rules and borrower information, see the Canada Mortgage and Housing Corporation.
Common move-up scenarios in Innisfil
Scenario A: Modest upgrade within Innisfil
If your new purchase price is slightly higher than your sale price, you may be able to port the full balance and add a small top-up. Ask how your lender prices the extra amount and whether they blend rates or create a separate segment. Also check the timing for appraisal and any fees that could reduce the savings from keeping your old rate.
Scenario B: Bigger upgrade with a much higher price
When you need a significantly larger mortgage, you have choices. You can port your existing balance and add a new portion at current pricing, or you can break and refinance everything if the all-in cost works out better. Compare the net effect of each path, including fees and any bridge financing. If your old mortgage was insured, ask your lender how a larger loan will affect insurance rules and down payment needs.
Scenario C: Sale and purchase dates do not match
If your closing dates are far apart, ask about bridge financing or a short-term loan to cover the gap. Confirm whether your lender allows you to complete the port within a post-closing window after your sale. Then compare the cost of bridging to the benefit of keeping your lower rate.
Scenario D: Changing who is on the mortgage
If you plan to add or remove a borrower, many lenders will treat that as a refinance rather than a straight port. That can affect your ability to keep your original rate and terms. Clarify this early so you know your options.
What to gather before you call your lender
- Your current mortgage contract and disclosure statement
- A recent payout statement from your lender
- Details of any prepayments you already made
- Your sale agreement and expected closing date
- Your new purchase agreement and proposed closing date
- The new property address and estimated purchase price
- Income documents and a list of household debts
- Any mortgage default insurance paperwork if your loan is insured
Smart questions to ask your lender or broker
- Do you allow porting on my mortgage product? Please confirm the policy in writing.
- What is your exact porting window before and after closing?
- Do you allow a partial port with a top-up? If yes, how is the top-up priced and can you provide a written illustration?
- Will I need a new appraisal? Who pays for it?
- Will you re-qualify my income and credit under current rules? What documents do you need?
- If I do not port, what is my current break penalty? Please provide a written calculation.
- If my mortgage is insured, does the insurer need to approve the port? How could loan-to-value affect this?
- Can I add or remove a borrower without losing portability?
- What legal, discharge, and registration fees apply to a port?
- If I port now and need to increase the mortgage later, how will that be handled?
How to compare your options
- Total out-of-pocket costs:
- Weigh the break penalty against portability fees and the cost of any bridge financing.
- Effective mortgage cost over time:
- If you port with a top-up, compare the blended effect on payments to a brand-new mortgage.
- Timeline feasibility:
- Make sure approval, appraisal, and legal work can complete before your closing dates.
- Qualification risk:
- Confirm that your current income and credit profile support a port under today’s rules.
- Contract constraints:
- Check whether changes to borrowers or property type limit portability.
- Insurance implications:
- If your loan is insured, ask how the new loan amount and value will affect approval.
A simple step-by-step plan
- Step 1: Get your mortgage contract and an up-to-date payout statement.
- Step 2: As soon as your purchase is firm, notify your lender and confirm the porting policy and window in writing.

- Step 4: Compare total costs, timing, and qualification requirements. Decide which path fits your goals.
- Step 5: Coordinate closing dates with your lawyer and lender so the mortgage instructions reflect your choice.
