Porting a mortgage Canada 2026 homeowners often assume is automatic is in fact a full new approval – and the deadline attached to it is measured in days, not months.
Porting means carrying your existing rate and terms to a new property instead of breaking the mortgage and paying a penalty.
When your current rate is better than today’s, that is worth real money. When it is not, porting can quietly cost you more than breaking would.
How Porting a Mortgage Canada 2026 Lenders Offer Actually Works
You sell your home, buy another, and move the existing mortgage across. The balance, rate and remaining term travel with you.
What does not travel is your approval. You requalify completely: income verification, credit check, debt ratios, appraisal on the new property, and the stress test.
A job change, a new car loan or a dip in credit since you last signed can all sink a port. Anyone whose income has changed should confirm eligibility before listing.
The new property must also satisfy the lender. Rural acreage, mixed-use buildings and some condos can be refused even when the borrower is fine.
The 8 Rules Worth Knowing
1. The porting window is short
Most lenders allow 30 to 120 days between your sale closing and your purchase closing. Outside that window, the port dies and the penalty applies.
Check your exact window in writing before you accept an offer on your home.
2. Same-day closings are simplest
Sell and buy on the same day and the port is mechanical. Different dates introduce bridge financing, extra legal work and additional cost.
3. Buying a more expensive home means blending
If you need to borrow more, the lender blends your existing rate with today’s rate on the additional amount, weighted by the two balances.
A blend-and-extend also resets your term, which can be good or bad depending on where rates sit.
4. Ask whether it is blend-to-term or blend-and-extend
Blend-to-term keeps your original maturity date. Blend-and-extend starts a fresh five-year term.
Lenders often quietly prefer the extend version because it locks you in longer. Ask for both quotes.
5. Downsizing can trigger a partial penalty
Borrowing less than your current balance usually means prepaying the difference – and that portion may attract a penalty.
Use your annual prepayment privilege first to reduce or eliminate it.
6. Variable mortgages are often cheaper to break than to port
The penalty on a variable mortgage is typically three months’ interest. If today’s rates are similar to yours, breaking and shopping the whole market may beat porting.
7. Collateral charges complicate a move
A collateral-charge mortgage must be discharged and re-registered, which adds legal cost. Ask how yours is registered.
8. Compare the total cost, not the rate
Add the penalty, legal fees, appraisal and discharge costs on each path, then compare against the interest difference over the remaining term.
Consumer guidance on penalties and prepayment is published by the Financial Consumer Agency of Canada.
When Breaking Beats Porting a Mortgage Canada 2026
Break instead of porting when today’s rates are at or below your current rate, when your lender’s blended offer is uncompetitive, or when your penalty is small – a three-month interest charge on a variable is often modest.
Also break when your lender will not approve the new property, or when your timing falls outside the porting window.
Fixed-rate borrowers should request their exact penalty in writing. The interest rate differential calculation varies significantly between lenders, and posted-rate methods can produce far larger figures than expected.
Running the Numbers Before You List
Do this three months before you list. Porting a mortgage Canada 2026 sellers plan properly starts with arithmetic, not assumptions.
Request your current balance, exact penalty figure, porting window and blend quote from your lender – all in writing.
Get one competing quote from a broker for a brand-new mortgage on the new property.
Compare total cost over the remaining term. If porting saves less than about a thousand dollars, the flexibility of a fresh mortgage is usually worth more.
Market benchmarks like the Bank of Canada’s published rates, available from the Bank of Canada, help you sanity-check whether the blended rate you are offered is reasonable.
The Bottom Line
Porting a mortgage Canada 2026 borrowers consider is a genuine saving when you hold a below-market rate and your circumstances are unchanged.
It is a trap when it locks you into an uncompetitive blended rate on a longer term simply because it felt like the default option.
Whichever way porting a mortgage Canada 2026 rules point in your case, the method is the same. Get the penalty in writing, get one outside quote, and let the arithmetic decide.
