How refinancing works in Canada

When you refinance, you replace your current mortgage with a new one — typically to access equity, get a better rate, or change your amortization.

The 80% LTV limit

In Canada, refinancing is capped at 80% of your home's appraised value. This means you cannot access all of your equity — you must leave at least 20% in the home. "Available equity" is the difference between that cap and your current mortgage balance.

Prepayment penalties

Breaking an existing mortgage before the term ends typically triggers a prepayment penalty — 3 months' interest for variable-rate mortgages, or the Interest Rate Differential (IRD) for fixed-rate mortgages. We help you determine whether the savings justify the penalty.

Common refinancing questions

Mortgage approvals, rates, terms, products, fees, and available lender options are subject to lender approval, borrower qualification, property review, market conditions, documentation, title review, and applicable laws.
