Dibz10-year fixed mortgage rates in Canada (2026): the long lock
10-year fixed mortgage rates in Canada: how they price against the 5-year, what a decade-long rate costs, the year-five penalty rule and a payment example.
A 10-year fixed mortgage locks your rate and payment for a full decade, typically the longest term Canadian lenders offer. There's no official 10-year average: the Bank of Canada puts 10-year loans in its "5 years and over" bucket, which averaged 4.05% for new insured mortgages and 4.49% for uninsured ones in July 2026. A lender's 10-year rate is usually noticeably higher than its 5-year rate, because you're buying twice the protection.
Whether that protection is worth the price is the whole question with a 10-year term. Here's how to think it through.
What a 10-year fixed mortgage is
For ten years, nothing about your rate or payment changes. With a 25-year amortization, you'd repay a large share of the loan before your first renewal. Compared with two back-to-back 5-year terms, you remove the risk of a bad rate at year five, and give up the chance of a good one.
Who the 10-year can suit
- Borrowers who can't absorb a payment shock, such as retirees on fixed incomes or single-income families with little slack.
- People who believe rates are more likely to rise than fall over the next decade and want that risk off their plate.
- Owners who plan to stay put for many years, with no expected move, separation or refinance.
Who it usually doesn't suit
- Anyone who might sell or refinance in the first five years. Early exits can trigger a large interest rate differential (IRD) penalty.
- Borrowers who expect rates to fall, or who would rather keep the savings of a cheaper shorter term.
- People who want maximum flexibility to restructure their debt.
How 10-year fixed rates are set
A 10-year mortgage is priced against long-term funding: 10-year Government of Canada bond yields (and the lender's own longer-term funding costs), plus a spread. That spread covers credit risk, operations and the cost of offering a decade of certainty, including the borrower's right to exit cheaply after five years (see below). We hold the 5-year yield (3.60% on October 2, 2026) but not the 10-year yield, so we can't chart that link.
Two patterns usually hold:
- When the yield curve slopes upward, the 10-year rate sits well above the 5-year rate.
- When the curve flattens, the gap narrows and the 10-year becomes relatively more attractive.
The chartered banks' posted 5-year rate was 6.09% on September 30, 2026. The Bank of Canada doesn't publish a posted 10-year rate.
What a higher 10-year rate costs
Since the 10-year premium varies by lender and over time, this chart shows how the cost grows as the rate rises above the 5-year-and-over average:

| Value | |
|---|---|
| 4.49% (5+ yr average) | $194,382 |
| 4.99% | $217,479 |
| 5.49% | $240,793 |
On a $500,000 loan, each half point adds about $23,000 in interest over the decade.
Insured vs uninsured
Insured mortgages (required with less than 20% down) usually get lower rates because the insurer carries the default risk: 4.05% vs 4.49% in the 5-year-and-over bucket in July 2026. The same pattern typically applies to 10-year pricing where lenders offer it to insured borrowers.
The five-year penalty rule
Under section 10 of the Interest Act, once five years have passed on a mortgage with a term longer than five years, an individual borrower can repay it with a penalty of no more than three months' interest. So a 10-year mortgage has two very different halves:
- Years one to five: the usual penalty, the greater of three months' interest or the IRD. With up to ten years left, the IRD can be very large if rates have fallen.
- Years six to ten: three months' interest at most. In effect, you can refinance or switch if rates fall in the second half.
That second-half flexibility is likely part of why 10-year rates carry a premium.
Renewal and the stress test
For a new 10-year mortgage, you'll be qualified at the greater of your contract rate plus 2 points or 5.25%. At renewal a decade later, staying with your lender doesn't require requalifying, and a straight switch to another lender generally doesn't either (since November 2024). Federally regulated lenders must send a renewal statement at least 21 days before maturity.
Worked example: $500,000 over 25 years
Using the July 2026 uninsured 5-year-and-over average (4.49%) as a floor, with two illustrative higher rates:
| Rate | Monthly payment | Interest over 10 years |
|---|---|---|
| 4.49% (5+ year average) | $2,765 | $194,382 |
| 4.99% (illustration) | $2,905 | $217,479 |
| 5.49% (illustration) | $3,049 | $240,793 |
At 4.49%, the balance after ten years would be about $362,632. After five years it would be $438,909; three months' interest on that balance is about $4,927, which is the most an individual borrower would pay to leave from year six onward. Figures use semi-annual compounding.

FAQ
What is the average 10-year fixed mortgage rate in Canada?
The Bank of Canada doesn't publish one. Its "5 years and over" average, which includes 10-year loans, was 4.05% insured and 4.49% uninsured for new mortgages in July 2026. Individual 10-year rates are usually well above a lender's 5-year rate.
Is a 10-year fixed mortgage a good idea?
It depends on your need for certainty and your plans. It removes renewal risk for a decade but usually costs more than a 5-year, and breaking it in the first five years can be expensive.
Can I break a 10-year mortgage after five years?
Yes. For individual borrowers, section 10 of the Interest Act limits the penalty to three months' interest once five years have passed.
What drives 10-year mortgage rates?
Mainly 10-year Government of Canada bond yields and lenders' long-term funding costs, plus a spread for risk and the borrower's right to exit cheaply after year five.
