Porting Your Mortgage When You Move: A Guide for Hamilton Families (2026)

If you're searching "porting your mortgage when you move," here's the short answer: in most cases, yes. You can transfer your existing mortgage, interest rate, and remaining term to your next home with the same lender, instead of breaking it and paying a prepayment penalty. With the Bank of Canada raising its policy rate to 2.50% on October 28, 2026, the rate you locked in a few years ago is more valuable than ever. For Hamilton families moving up the Mountain, understanding mortgage porting could save you thousands.

What Does Porting Your Mortgage Mean?

When you sell your home and buy another, you have two paths: take a brand-new mortgage at today's rates, or ask your lender to port your existing one. Porting transfers your current balance, interest rate, and the rest of your term to the new property. The mortgage continues almost exactly as it would have, just attached to a different address.

That continuity is the whole point. Families who locked in a rate a few years ago can keep paying it for the remainder of their term, no matter what happens to the market in between.

Why Porting Matters More After the October 2026 Rate Increase

On October 28, 2026, the Bank of Canada raised its policy rate to 2.50%, its first increase since July 2023, and prime lending rates moved up to roughly 4.70%. New five-year fixed rates now sit well above what many existing homeowners are paying.

Here's the simple math: on every $100,000 you owe, each 1% of interest costs about $1,000 a year. If you owe $400,000, holding a rate just 1% lower than today's saves you around $4,000 every year for the rest of your term. That's money that can stay in your family's budget for school, activities, or the next renovation.

Can You Port Any Mortgage?

Not every mortgage has a portability clause, so check yours first. Most fixed-rate products allow porting. Many variable-rate and restricted "no-frills" fixed products don't, though some lenders let you convert to fixed first so you can port. Porting works only with your current lender, so it's not a chance to shop around, and you'll still need to qualify again under the federal stress test on a larger mortgage.

If your mortgage is insured, porting and increasing is typically capped at 90% of the new home's value. Your mortgage professional can confirm your exact limit.

How Mortgage Porting Works, Step by Step

1. Confirm portability before you house hunt. Call your lender or mortgage broker and ask whether your current product can be ported, so there are no surprises later.
2. Get your payout statement. It shows your exact balance, rate, and what you'd pay to break, which is your baseline for deciding between porting and a new mortgage.
3. Time your closings. Lenders typically want your sale and your purchase to close within 30 to 120 days of each other. If you buy before you sell, you may need bridge financing to cover the gap.
4. Ask about a rate hold. Most lenders will hold your current rate for 90 to 120 days while you find and close on your next home.
5. Plan the top-up. If your next home costs more than your balance, the extra amount is borrowed at today's rate, often blended with your old rate in what's called a blend-and-extend.

What Porting Costs, and What It Saves You

The big win is that there's no prepayment penalty on the portion of the mortgage that moves to your new home. If your new mortgage is smaller than your old balance, the extra amount you pay down can trigger a penalty, usually three months' interest or the interest-rate differential, whichever is greater. Lenders also charge small administration fees, often $100 to $300, plus the usual legal and appraisal costs of any purchase.

Compare all of that with the full penalty of breaking a term at today's higher rates. For most move-up families, porting is the cheaper path by a wide margin.

Porting on the Hamilton Mountain: A Move-Up Reality Check

On the Mountain, the typical move-up family sells a bungalow or side-split in the $700,000 range and buys more room in Ancaster, Binbrook, or Upper Stoney Creek. With port-and-increase, they keep their low rate on the existing balance and pay today's rate only on the difference. That's how a bigger home stays within reach when rates are rising.
