When and How to Refinance Your Mortgage in Canada

If your mortgage is more than a couple of years old, you may be paying more than necessary. Refinancing — switching to a better rate, different product, or new lender — can save you thousands over the remaining term. This guide explains when refinancing makes sense and how to do it in Canada.

When Refinancing Makes Sense

Refinancing typically makes sense when market rates have dropped significantly below your current rate, your financial profile has improved (higher income, better credit score, lower LTV through property appreciation), you want to switch from variable to fixed rate (or vice versa), you want to access equity for renovations or other purposes, or you want to change your loan term.

How Refinancing Works in Canada

You can refinance up to 80% of appraised value. Fixed-rate early termination penalty is the greater of 3 months’ interest or the Interest Rate Differential (IRD) — this can be thousands of dollars. Variable-rate penalty is typically just 3 months’ interest. At renewal (every 1-5 years), switching lenders is free. Blend-and-extend with your current lender avoids penalties. Always shop at renewal — your bank’s first offer is negotiable

Calculating the Break-Even Point

The break-even point is how long the monthly savings take to exceed the costs of switching. Divide total switching costs by monthly savings to get the number of months. If you plan to stay longer than the break-even point, refinancing makes financial sense. Use our mortgage calculator to model the savings.

When NOT to Refinance

Refinancing does not always make sense. If the rate difference is small and switching costs are high, you may be better staying. If you are close to paying off the mortgage, the savings period is too short. If your property has decreased in value, your LTV may be worse, potentially increasing your rate.
