Porting lets you move your existing mortgage — its rate, remaining term, and balance — from the home you are selling to the home you are buying in Alberta, instead of breaking the mortgage and paying a penalty. It makes the most sense when your current rate is attractive compared to what you could get today and you have significant time left in your term. Your lender still has to approve you, the new property, and the timing.

What does porting a mortgage actually mean?

You sell one home and buy another, and your existing mortgage moves with you to the new property. The rate and the time remaining on your current term carry over for the ported balance.

Your closing dates matter. Most lenders allow only a limited window between the sale of your old home and the purchase of your new one for a port to work, and that window varies by lender and product. Miss the window and the mortgage is treated as broken, with any penalty that applies. See breaking your mortgage early: IRD and posted-rate penalties.

When does porting make the most sense?

Porting is usually strongest in three situations. Your current rate is better than what a new mortgage would offer today. You are well into a term but not close to renewal, so a break penalty could be meaningful. Or you want payment stability and your remaining term still fits your plans.

It is weaker when your renewal is near, when your current rate is not competitive, or when the new purchase requires so much new borrowing that the blended result no longer helps. Run the comparison both ways — port versus a fresh mortgage — before deciding. A Mortgage Renewal Check is a good framework for that math even mid-move. The alternative on timing is switching lenders at renewal instead of porting.

What is a blend-and-port, and how does it work?

If the new home costs more and you need a larger mortgage, many lenders offer a blend-and-port. The existing balance keeps your current rate for its remaining term, the new money is priced at current rates, and the two combine into one blended rate and payment.

Ask for the blended rate, the new term structure, and what happens at renewal in writing, then compare it against a completely new mortgage.

What are the qualification traps when the new home costs more?

Porting is a new approval, not a rubber stamp. The lender re-qualifies you on income, debts, and credit, and it appraises and approves the new property as security. A job change, new debt, or a property the lender will not accept can stop a port that looked simple on paper.

The extra borrowing in a blend is qualified as new debt as well. Buyers are often surprised that needing more money is the point where a port gets difficult — the larger the top-up, the more the file looks like a brand-new application, because it largely is.

What should you confirm before you list or offer?

Confirm four things early: that your mortgage is portable, how long your port window is, whether your sale and purchase dates can fit inside it, and what penalty you would pay if the port fails. Get those answers before conditions come off, not after. If the dates do not line up, see bridge financing when the buy and sell dates don’t line up.

If you are also a first-time buyer on the purchase side of a family move, the First Home Guide for Edmonton covers the approval steps that still apply. Planning the port and the purchase together avoids the most common timing surprises.
