Renewing Your Mortgage in Fall 2026: The Math to Do Before You Sign

Renewing your mortgage in Canada in fall 2026 means renewing into a very different rate world than the one you signed in. The average five-year fixed uninsured mortgage rate was about 2.36% in July 2020, according to CMHC figures reported by the Canadian Press, versus roughly 3.95% this past July, and today's best advertised rates run higher still. Roughly 1.15 million Canadian households are renewing in 2026, making this one of the most consequential renewal periods in decades. Before you sign anything, run the fixed-versus-variable math, understand your penalty options, and negotiate, because renewal is one of the few moments you have real leverage. All figures below are as of early October 2026.

Key takeaways

• The Bank of Canada has held its policy rate at 2.25% since October 2025, keeping the big-bank prime rate at 4.45%, the base for variable mortgage pricing.
• As of October 2, 2026, the best advertised high-ratio 5-year fixed rates were around 4.34%, with the best 5-year variable near 3.4%. Averages are higher: the national average conventional 5-year fixed sits near 5%.
• CMHC says the renewal wave peaked in 2025, with 2026 volumes about 13% lower, but some 1.15 million mortgages are still renewing this year.
• Variable-rate mortgages now make up 42% of new mortgages at chartered banks (February 2026), the most popular product on offer, reflecting borrowers betting on lower or flat rates.
• If you break a fixed mortgage early, the penalty is the greater of three months' interest or the interest rate differential (IRD); big-bank IRD calculations can reach five figures. At renewal maturity itself, payout and switching are penalty-free.

The 2026 renewal landscape

The pandemic-era mortgage cohort is cycling through. Millions of borrowers who locked in five-year terms in 2020–2021 at or near historic lows are renewing at rates several percentage points higher. According to CMHC, about 1.15 million mortgages are renewing in 2026 alone. The wave peaked in 2025, CMHC's Spring 2026 Residential Mortgage Industry Report says, with 2026 renewal volumes expected to come in about 13% lower, but the pressure is still historically high.

The strain shows up in the arrears data. Mortgages in arrears hit 0.29% in July 2026, up 6 basis points in a year and the highest level since May 2014, according to Better Dwelling's analysis. Banks have also shrunk their mortgage books to 4.91 million mortgages in July, a six-year low. The system is absorbing the shock, but individual borrowers are feeling it.

What that means in dollars: on a $400,000 balance with 25 years of amortization remaining, a 4.5% rate costs about $2,224 a month in principal and interest, while 3.5% costs about $2,003, a difference of roughly $221 a month, or about $13,250 over five years. Those are illustrative calculations; your lender's compounding and your exact amortization change the numbers. The point is that even a half-point difference in the rate you secure at renewal is real money.

Fixed vs. variable in fall 2026

As of October 2, 2026, the snapshot looks like this:

Rates cited are for high-ratio (insured) borrowers in most provinces; uninsured borrowers generally pay a premium. Treat aggregator figures as a range, not a promise, they update at different times and treat insured and uninsured products differently.

The pricing relationship between fixed and variable has flipped. Variable rates now trade at a discount to comparable fixed terms, and borrowers have noticed: by February 2026, variable-rate mortgages had risen to 42% of new mortgages extended at chartered banks, the single most popular product on offer, while traditional 5-year fixed terms accounted for only about 11%, per CMHC.

The trade-off hasn't changed, though. Fixed gives you certainty of payment for the term; variable gives you a lower rate today with exposure to rate moves. And the October 28 Bank of Canada decision matters here: UBS Global Research now forecasts a 25-basis-point hike, which would push prime to about 4.70% and lift variable payments. Other forecasters expect the Bank to hold at 2.25% through the rest of 2026. You can't know the outcome, so size your decision for both. See our analysis of the October 28 Bank of Canada decision for the full hike-vs-hold breakdown.

Shorter fixed terms are worth a look in this environment. As of early October 2026, best advertised high-ratio rates included 3-year fixed around 4.64% (nesto) and 2-year fixed around 4.97–5.09%. A shorter term can make sense if you expect rates to ease later and you don't mind re-negotiating sooner, but shorter terms mean repeating the exercise more often.

The penalty math you need to understand

At renewal maturity, there is no penalty. Paying out your mortgage, switching lenders, or refinancing when your term ends costs you nothing in prepayment charges. The penalty math below applies only if you break a mortgage before the end of a term, which is exactly why renewal is your moment of maximum flexibility.

If you do break a closed fixed-rate mortgage early, the lender charges the greater of two calculations:

• Three months' interest: three months of interest on your outstanding balance at your contract rate. On a $300,000 balance at 4%, that's $300,000 × 4% × 3/12 = $3,000.
• Interest rate differential (IRD): the difference between your contract rate and the lender's current rate for a term matching your remaining time, multiplied by your balance and the months remaining.

The IRD is where penalties get painful, and where the lender you chose matters enormously. Canada's Big 6 banks calculate the IRD using their posted rates minus your original discount (the "posted rate method"), which inflates the penalty substantially. Monoline lenders typically use a fairer contract-rate-based method. Mortgage Renewal Hub's 2026 analysis illustrates the gap: on a $300,000 mortgage with three years remaining, the same scenario can produce roughly a $3,000 penalty at a monoline versus $10,000–$13,000 at a Big 6 bank. Variable-rate mortgages, by contrast, are almost always just three months' interest, no IRD.

The practical implication: if you are switching from a Big 6 fixed mortgage mid-term (for example, to grab a much lower rate), get the penalty in writing before you commit. And if your term is ending, you never pay it at all.

How to negotiate your renewal

Renewal offers are opening bids, not final prices. Your current lender sends you a renewal letter at their posted or near-posted rate, counting on inertia. Research consistently shows many borrowers accept the first offer, don't be one of them.

1. Start 90–120 days out. Most lenders offer rate holds of 90 to 120 days on fixed rates. Getting a hold early protects you if rates rise before your term ends, while letting you take a lower rate if they fall.
2. Get competing quotes. Pull advertised rates from at least two comparison sources and get one written quote from a mortgage broker or a different lender. A real competing number is your leverage.
3. Ask for the discount, not the posted rate. Lenders publish posted rates but discount heavily, self-reported borrower data in October 2026 showed TD customers at 4.30% on a 5-year fixed versus a 5.35% posted rate, for example. Negotiate down from posted.
4. Ask for the prepayment terms too. Rate isn't the only cost. Compare prepayment privileges (most lenders allow 15–20% annual lump-sum payments and payment doubling), penalty calculation methods, and porting options.
5. Switching lenders is penalty-free at maturity, but you will re-qualify under current rules, including the federal mortgage stress test, which requires federally regulated lenders to qualify you at a rate above your contract rate. Have your income documents ready.

What to do if the new payment is a stretch

If the renewal math doesn't fit your budget, you have options short of defaulting, but act before you miss a payment:

• back to 25 or 30 years at renewal to lower the payment (you'll pay more interest over time).Extend your amortization
• Ask about a blended rate if you're mid-term and want certainty without the full penalty.
• Consider a shorter term to buy time if you expect your income to rise or rates to ease.
• Talk to your lender about hardship options if you're already struggling, lenders have formal processes, and asking early is always better than asking after arrears.

Mortgage arrears nationally are rising but remain low by historical standards, 0.29% in July 2026, and stress is concentrated in highly leveraged pockets like Toronto. The data suggests a system adjusting, not a crisis.

The bottom line

Renewal is the one moment in the mortgage cycle when you pay no penalty to switch, shop, and renegotiate, so treat your lender's first renewal letter as a starting bid. Run the fixed-versus-variable math at today's rates and at a quarter-point higher, get your rate hold 90–120 days out, and bring a competing quote to the table. In a year when about 1.15 million Canadians are renewing and the Bank of Canada itself is debating whether to hike, the borrowers who do the math will do fine either way.
