Mortgage Porting in BC: How to Keep Your Rate When You Move

• Porting protects a below-market rate, nothing else: if your contract rate is higher than today's roughly 3.99% insured five-year fixed, breaking and paying the penalty can be cheaper than porting.
• You still have to qualify from scratch: the lender re-checks income, credit and the new property, and it re-applies the OSFI B-20 stress test at your rate plus 2% or 5.25%, whichever is higher.
• Insured mortgages usually carry the premium forward: with CMHC premiums running 0.60% to 4.00% of the mortgage, that portability alone can be worth five figures on a Coquitlam purchase.

Every spring I get the same call from Tri-Cities homeowners: "We found a bigger place in Port Moody, but we're two years into a five-year term. Are we stuck?" Usually not. Most mortgages in Canada are portable, meaning you can carry your existing rate, balance and remaining term to the new property instead of breaking the contract.

Whether that is smart depends entirely on the numbers. Rate tracking published by Canadian Mortgage Trends (2026) shows insured five-year fixed offers sitting near 3.99% this summer, with prime at 4.95%. If you signed at 5.29% in 2023, porting that rate forward is the last thing you want to do.

I've seen porting save a Burquitlam family close to $14,000 in penalty, and I've seen it cost another family money because nobody compared it to simply breaking. Here is how I walk clients through it, step by step, in plain language.

Porting means carrying your existing mortgage, its rate and the rest of your term over to a new property rather than breaking the contract and paying a prepayment penalty. It pays off when your current rate sits below what the market offers today and your lender approves both you and the new home.

What you need before you start

Before I can tell anyone whether porting makes sense, I need four things: your original mortgage commitment or last renewal letter, a written payout and penalty quote from your lender, your current balance and remaining term, and a realistic price range for the next home. In my experience, most people have not opened that commitment letter since signing day, and the portability clause is buried in it.

The insurance angle people forget

If you put less than 20% down, your mortgage is insured, and porting normally carries that default insurance to the new property. CMHC (2026) sets premiums between 0.60% and 4.00% of the insured mortgage amount. On a $700,000 mortgage at the top of that range, re-paying the premium on a brand new insured mortgage is roughly $28,000. Porting can preserve most of that.

Note: portability is not universal. Most fixed-rate mortgages are portable. Many variable-rate products are not, and no-frills or "low rate special" mortgages from certain lenders are often locked in with penalties that cannot be avoided at all.

Consider a Burquitlam couple with a 2.89% rate and 26 months left, trading their condo for a Burke Mountain townhouse. Porting that rate forward is real money. Now consider a Maillardville owner carrying 5.44% from a 2023 signing. Porting that forward would be a mistake, and I would rather look at breaking, paying the penalty and resetting into today's pricing. That comparison is the same one I run during a mortgage renewal or refinance review, just with a moving truck attached.

Porting is a re-application, not a transfer of paperwork. You submit a fresh mortgage application on the new property, the lender re-underwrites you, and if approved, they attach your existing rate and term to the new loan. Here is the order I work in with clients.

1. Find the portability clause. Read your commitment letter or call the lender and ask two questions: is this mortgage portable, and what is the port window in days?
2. Confirm the port window. Most lenders allow 30 to 120 days between the sale of the old home and the completion of the new one. A few require same-day completion. Miss the window and the rate is gone.
3. Requalify under the stress test. Federally regulated lenders qualify you at your contract rate plus 2% or 5.25%, whichever is greater. Income, credit and debts are all re-checked.
4. Get the penalty quote in writing. Fixed mortgages usually trigger an interest rate differential; variable mortgages typically use three months' interest. Ask for the exact dollar figure and the calculation date.
5. Compare porting against breaking. With five-year fixed pricing near 3.99% in 2026 per RateSpy, a higher legacy rate often makes breaking the cheaper path once the payment savings are added up over the remaining term.
6. Do the blend math if you need more money. Buying up means a second component at today's rate, blended into your existing rate. Ask whether it is a blend-and-extend or a blend-to-term, because the resulting rate differs.
7. Line up completion dates and bridge financing. If your Port Coquitlam sale closes on the 15th and your purchase closes on the 30th, you need bridge financing for those 15 days.
8. Submit the full package. Appraisal, purchase contract, strata documents, income confirmation, then instruct your lawyer or notary early.

Pro Tip: start step one before you list. CREA's 2026 national statistics show homes still moving quickly in tight Metro Vancouver segments, and I've watched buyers accept an offer with dates their lender could never accommodate. My walkthrough of the mortgage application process covers the same sequence in more detail.

The biggest mistake is treating porting as automatic. Your rate is portable; your approval is not. The second biggest is falling in love with a property the lender will not finance, which kills the port even when your file is perfect.

Assuming your income still qualifies

If you left a salaried job to start a business between homes, the lender may not count that income yet. This is common in the Tri-Cities, and it is why I treat self-employed mortgage files differently: two years of T1 Generals and Notices of Assessment from CRA, or a lender that accepts stated income with a larger down payment.

Buying a property the lender rejects

I've seen ports fall apart over age-restricted stratas, rental-restricted buildings, past remediation history, units under 500 square feet, and acreage outside a lender's service area. Ask before you write the offer, not after.

Ignoring the blend

Clients hear "you keep your rate" and picture the whole new mortgage at 2.89%. If you are borrowing an extra $250,000, that portion prices at today's market and blends upward. TD Economics (2026) expects BC prices to keep grinding higher through the year, which means most movers are borrowing more, not less, and the blended rate deserves a hard look.

Stretching the budget on the move

Moving costs, property transfer tax and a bridge loan all land in the same month. The 2026 MNP Consumer Debt Index keeps finding that close to half of Canadians are within $200 of not covering their monthly obligations. I would rather you port into a payment with breathing room than the maximum a calculator spits out.

Note: porting into a smaller mortgage can still trigger a partial penalty on the difference. Ask about that specifically.

If you are unsure which path is cheaper, reach out and I can run both scenarios for you. My services are free to you, since lenders pay me at closing.

Porting is a good tool, not a default answer. If you are carrying a rate below today's market and your lender's timelines line up with your sale and purchase dates, porting protects your rate, your term and often your default insurance premium. If your rate is above market, the penalty may be worth paying to reset lower.

The only way to know is to put both scenarios side by side with real numbers: your penalty quote, today's pricing, the blended rate on the new money, and the bridge financing cost. That takes me about twenty minutes.

Whether you are moving within Coquitlam, heading to Port Moody, or leaving the Tri-Cities entirely, get in touch and I'm happy to walk you through it. No pressure, no cost, and no jargon.
