Refinancing Your Mortgage in 2027: Is It Worth It?

By Jatin Dua · Broker of Record, RE/MAX Quantum Realty · Updated 2 November 2026 · 10 min read — Refinancing in 2027? The 80% equity limit, penalties, stress test, debt and suite examples, and when it actually pays in Ontario.

This guide is for Ontario homeowners thinking about refinancing in 2027, whether to pull cash out, pay off other debt, fund a project or chase a lower rate. You will get the rules that limit how much you can borrow, what breaking a mortgage costs, worked examples at current rates, and a simple test for whether it is worth it.

Is refinancing your mortgage worth it in 2027?

Refinancing means replacing your current mortgage with a new one, usually larger, and often before your term ends. The new loan pays off the old one. You keep the difference as cash or use it to clear other debts.

In 2027 the answer depends on why you want to do it. Borrowing costs went up in late 2026. On 28 October 2026 the Bank of Canada raised its policy rate to 2.50%, its first increase in more than three years, and said a further increase could be needed. Big-bank prime rose to 4.70% the next day. On 10 November 2026, RBC’s special offer for a five-year fixed mortgage was 5.14%, and its posted five-year rate was 6.19%.

That changes the maths:

• Refinancing for a lower rate rarely pays in 2027 unless your current rate is well above today’s offers.
• Refinancing to replace expensive debt can still make sense, because credit cards and unsecured loans usually cost far more than a mortgage.
• Refinancing to add value, such as a legal secondary suite, can work well, and there is a special insured program for it.

How much equity can you take out when you refinance in Ontario?

Usually up to 80% of your home’s appraised value, minus everything you owe on it. The Financial Consumer Agency of Canada (FCAC) uses this rule in its guide to borrowing against home equity. The value comes from an appraisal, not from the price you hope to get.

The formula is simple:

• Maximum new mortgage = 80% of appraised value
• Cash available = that number, minus your current balance, minus fees

Here is an example using real numbers. The median detached sale price in Brampton for January to October 2026 was $950,000. With a $600,000 mortgage, 80% of $950,000 is $760,000, which leaves about $160,000 before costs. For the same months of 2024, the Brampton median was $1,127,250. At that value, 80% would have been $901,800, leaving about $301,800. Lower prices cut the available cash by roughly $140,000 in this example without the owner doing anything.

A home equity line of credit (HELOC) is capped lower: FCAC says up to 65% of your home’s value for the revolving part. My comparison of HELOC vs refinance vs selling explains when each one fits.

How have GTA home prices changed your equity since 2024?

Prices are lower than two years ago in most of the GTA, so many owners have less equity than they assume. Here is how median sold prices moved between the first ten months of 2024 and the same period of 2026.

Source: TRREB MLS data via REALM, January–October 2026 vs the same period of 2024. Medians are for each municipality or TRREB district, not for any one street or building.

TD Economics, writing in June 2026, put GTA prices roughly 26% below their peak. It also explained a widely reported Bank of Canada estimate: nearly 10% of Toronto-area borrowers renewing in 2027 might be unable to refinance. TD stressed that this is about refinancing, not renewing. You can usually renew with your own lender without requalifying, but a refinance needs new approval, a new appraisal and enough equity. TD estimated that affected owners would need roughly $50,000 more equity for a typical condo and $110,000 for a typical detached home to get back to 80% loan-to-value.

What does it cost to refinance a mortgage before the term ends?

If your mortgage is closed and you break it mid-term, expect a prepayment penalty. FCAC says the penalty is usually the higher of three months’ interest or the interest rate differential (IRD). Lenders usually use the IRD when your rate is higher than their current rate and you signed less than five years ago. Each lender calculates the IRD its own way, and methods based on posted rates can make it much larger.

FCAC lists the other costs to check:

• Administration and reinvestment fees
• Appraisal, title search and title insurance fees
• Legal fees and a discharge fee for the old charge
• Repaying any cash back you received when you took the mortgage

Some lenders will pay part of these costs to win your business, so ask. At the end of your term there is no prepayment penalty, which is why many owners wait for maturity before refinancing. My guide to how lenders calculate the IRD shows why two lenders can quote very different penalties on the same balance.

Before you call a lender, use the calculator below to see what payment and price range your income supports at today’s rates.

Does refinancing to a lower rate pay off in 2027?

Only if the interest you save before your current term would have ended is bigger than the penalty and fees. Here is a worked example with a $600,000 balance, 22 years left on the amortization and 24 months left in the term.

In this example you lose money before paying a single legal or appraisal fee. The gap would need to be much wider, or the term much longer, for a rate-only refinance to work. Also remember that a new five-year term locks you in again, and nobody knows where rates will be when your old term would have ended.

Is refinancing to consolidate debt a good idea?

It can be, if you also change the habit that created the debt. Moving high-interest balances into your mortgage cuts the rate sharply. The catch is time. Spread over 25 years, even a low rate adds up.

Take $50,000 of debt rolled into a mortgage at 5.14%:

• Paid over 25 years: about $295 a month and about $38,440 in total interest, if the rate stayed the same.
• Paid over 5 years: about $946 a month and about $6,732 in total interest.

The smart version is to refinance, then use your prepayment privileges to clear that $50,000 within a few years. FCAC also warns that borrowing against your home puts the home at risk if you cannot repay, and that easy access to credit can tempt you to borrow again. Lower or close the credit cards you paid off.

Can you refinance to build a basement or garden suite?

Yes, and this is the one case where you can go above 80%. Insured refinancing is now allowed to fund a secondary suite. CMHC’s Refinance product allows:

• Up to 90% of the home’s value after the work, on homes with a lending value below $2,000,000
• An amortization of up to 30 years
• Up to four units in total, with you or a close relative living in one

There are firm conditions. The suite must be self-contained and legal under local by-laws. It cannot be a short-term rental, which CMHC defines as fewer than 90 consecutive days. The new money must go to building the suite, not to taking equity out, and CMHC wants the financing approved before construction starts or at an early stage. The lending value is the lower of the as-improved value or the current value plus the cost of the work.

Example: a home worth $1,000,000 today plus a $200,000 suite gives a lending value of $1,200,000. At 90%, the maximum loan is $1,080,000. A standard refinance on the same home tops out at $800,000. A mortgage insurance premium applies, and not every lender offers the product. If you are weighing a suite, my guide to laneway suite costs and rules in Toronto covers the building side.

Do you have to pass the stress test to refinance?

Yes, at a federally regulated lender such as a bank. The Office of the Superintendent of Financial Institutions (OSFI) expects lenders to qualify you at the greater of your contract rate plus 2 percentage points or 5.25%. At a 5.14% contract rate, you qualify at 7.14%.

On a $760,000 refinance over 25 years, the real payment at 5.14% is about $4,481 a month. The lender tests whether you could carry about $5,389. If your income has dropped or your other debts have grown since you bought, this is where refinances fail.

Compare that with a straight switch at renewal: OSFI does not expect the stress test when you move an uninsured mortgage to another federally regulated lender with no increase in the loan or the amortization. Adding money makes it a refinance, so the test applies again. My explainer on how the stress test works has more detail.

Should you refinance now or wait until your renewal?

If your term ends in 2027 or early 2028, waiting is often cheaper because the penalty disappears at maturity. Other options to compare first:

• Blend-and-extend. FCAC explains that some lenders let you extend early with a blended rate and no prepayment penalty, though fees may apply.
• Borrow back prepayments. If you made lump-sum payments, your lender may let you re-borrow them.
• A HELOC for smaller or staged needs, accepting a variable rate.

The Bank of Canada’s next decision is on 9 December 2026, and its next Monetary Policy Report comes on 27 January 2027. Forecasts differ, so do not refinance on a rate guess.

What to do next

1. Ask your lender for a written penalty quote and your exact balance, remaining term and amortization.
2. Get a realistic value range for your home, then work out 80% of it minus what you owe.
3. Write down the purpose of the money and how fast you will repay it.
4. Compare a refinance with blend-and-extend, waiting for maturity and a HELOC, including all fees.
5. If a suite is the goal, confirm zoning and permits and ask lenders about CMHC Refinance before work starts.
