Best Mortgage Refinance Rates in Canada
Comparing mortgage refinance rates among lenders can help you save money and secure better terms for the next phase of your mortgage.Editor’s Note: The Bank of Canada has lowered its overnight rate to 2.5%, a decrease of 0.25 percentage points. This was the first rate cut in six months. In its announcement, the BoC stated, “After remaining resilient to sharply higher US tariffs and ongoing uncertainty, global economic growth is showing signs of slowing.” Read more about the cut and how it could affect home buyers.
Mortgage refinance rate update: September 2025
With mortgage rates generally around 4%, it’s not an ideal time to refinance a mortgage in Canada. But refinancing might get a little cheaper later in September.
Government bond yields, which lenders use to price their fixed mortgage rates, have trended down in the first week of the month. When yields dip for a sustained period of time, it generally gives lenders room to lower their fixed-rate offers.
We haven’t seen much movement yet. Three- and five-year fixed refinance rates are generally around 4.3% or higher at mortgage brokerages.
Variable refinance rates could decline as soon as September 17, when the Bank of Canada will announce its next overnight rate decision. Disappointing GDP and unemployment numbers are strong arguments in favour of a rate cut, even though inflation remains well above the Bank’s target of 2%.
Until the Bank lowers the overnight rate, variable refinance rates are likely to hover around 4.2%.
Rate cuts and lower bond yields are generally signs of a lagging economy, so even if affordability improves for buyers in September, we may not see housing demand pick up until buyers see more stability in the economy.

Why are mortgage refinance rates higher?
There are various theories around why mortgage refinance rates are typically higher than purchase mortgage rates.
One is that lenders assume greater risk when they extend homeowners more credit over a longer period of time. If you refinance your mortgage, borrow against your home equity and opt for a longer amortization period, for example, it adds extra time during which you might fail to make good on your mortgage payments.
Another possible explanation is that refinances can result in lower profits for lenders. Let’s say you agree to a five-year fixed rate mortgage at 5% but are able to refinance at 3% after two years. The result is three years of savings for you, but three years of reduced earnings for your lender. Charging a higher rate on your refinance mitigates these losses. (Hefty prepayment penalties help, too.)
How to get the best mortgage refinance rate
Refinancing a mortgage requires applying for a new home loan. To be approved, the lender will put your finances under the microscope again. Before offering you the best refinance rate, your lender will want to see:
Debt service ratios well below the limits laid out by the Canada Mortgage and Housing Corporation and other mortgage insurance providers. These limits include a gross debt service ratio of 39% and a total debt service ratio of 44%
The highest credit score you can manage. A score of 700 or higher, for example, will demonstrate creditworthiness to lenders.
On-time mortgage payments since becoming a homeowner. Missed mortgage payments are the reddest of flags.
Your current lender may not approve a refinance if your credit score has decreased or you’re experiencing debt issues. That doesn’t mean you’re out of options. There are plenty of B lenders that specialize in bad credit mortgages where you may be able to get refinanced.
Other mortgage refinance costs to consider
With all things mortgage-related, there’s more to think about than just the interest rate you’re offered. That’s especially true when it comes to refinancing, where other costs can include:
Prepayment penalties. Refinancing before the end of your mortgage term means breaking your mortgage contract, paying off your loan in full ahead of time and paying what can be a hefty penalty. How much you pay will depend on your interest rate type and how your lender calculates your penalty amount.
A home appraisal. Your lender will use a professional appraisal to determine your home’s value before deciding how much you can borrow against it.
Legal fees. As with your original mortgage, a real estate lawyer will be required to facilitate the transaction.
Mortgage discharge fees. You may have to pay to discharge your mortgage if you refinance with a new lender.
An opportunity to lock in at a lower rate will always sound enticing, but the benefits have to be weighed against the total cost to ensure you’re making the right long-term decision for your household.
