What porting means in Canada and how a borrower may move an existing mortgage to a new property.
Porting is the ability to move an existing mortgage from one property to another, usually when the borrower sells the current home and buys a new one.
Porting can help a borrower keep a favourable rate or avoid an early-break penalty when moving homes during the term. In a volatile rate environment, that feature can be extremely valuable.
Porting is usually offered only if the mortgage contract allows it and the new property and borrower still meet the lender’s approval standards. If the new home costs more, the lender may blend the old mortgage with new funds. If it costs less, the borrower may still need to manage prepayment rules or partial penalties.
You have a strong fixed rate that would be painful to lose. Instead of breaking the mortgage entirely when you move, the lender lets you port the existing balance onto the new home and top up the loan if needed.
Porting is not automatic just because the borrower is staying with the same lender. The product, timing, and approval still matter.
Borrowers also sometimes treat porting and switching as opposites. They solve different problems. Porting usually keeps the lender while moving the property. Switching keeps the property while changing the lender.
Timing windows, top-up rules, bridge needs, and property eligibility vary by lender and contract. A port feature that sounds flexible in marketing can still be narrow in practice.
