The short answer is probably not.
When Canadians shop for a mortgage, it’s natural to focus on one thing—the interest rate. After all, even a small difference in rate can save money over time.
But what many borrowers don’t realize is that the lowest mortgage rate can sometimes come with the highest cost if life changes.
At Mainstream Mortgages, we encourage clients to look beyond the headline rate and ask a much more important question:
“What will it cost me if I need to make changes before my mortgage term ends?”
Life Doesn’t Always Go According to Plan
Most homeowners don’t expect to break their mortgage early.
Yet every year thousands of Canadians do because of:
- Selling their home
- Job relocation
- Divorce or separation
- Growing families
- Downsizing
- Refinancing to consolidate debt
- Purchasing an investment property
- Health or financial changes
- Unexpected repairs or expenses
Statistics have consistently shown that many fixed-rate mortgages are not held for the full five-year term. That’s why understanding your mortgage penalty before you sign is just as important as understanding your interest rate.
The Hidden Cost of Ultra-Low Fixed Rates
Many banks advertise incredibly attractive fixed mortgage rates by offering significant discounts from their posted rates.
While that sounds great up front, those same discounts can become very expensive if you need to break your mortgage.
Most major lenders calculate fixed-rate mortgage penalties using the greater of:
- Three months’ interest, or
- The Interest Rate Differential (IRD)
The IRD compares your discounted contract rate to the lender’s current rate for a comparable remaining term. The exact calculation varies by lender, but many banks use their own posted rates and apply the original discount you received when determining the penalty.
A Simplified Example
Imagine:
- Bank posted 5-year rate: 5.99%
- You receive a discounted mortgage at 3.99%
- Your original discount was 2.00%
Two years later, you need to sell your home.
Instead of comparing your contract rate against today’s advertised special rates, the lender may begin with today’s posted rate for the remaining term and then subtract your original 2.00% discount before calculating the Interest Rate Differential.
Because the calculation is based on the lender’s posted-rate structure rather than simply comparing advertised market rates, the resulting penalty can be significantly higher than many borrowers expect.
Every lender has its own penalty formula, but the important takeaway is simple:
A lower rate today doesn’t always mean lower costs tomorrow.
Cash Back and Credit Card Incentives
Cash-back incentives and premium credit card offers can also be attractive.
Who wouldn’t like receiving a few thousand dollars at closing or earning extra reward points?
The catch is that these promotions often come with additional conditions.
Breaking the mortgage early may require repayment of some or all of the cash-back incentive, reimbursement of promotional benefits, or trigger larger penalties depending on the lender’s mortgage agreement.
Those rewards can disappear surprisingly quickly if your plans change.
Always read the fine print and understand exactly what happens if you sell, refinance, or switch lenders before the term expires.
How much money will it cost if you need to RETURN your mortgage to the bank? The restocking fee can be insurmountable.
Variable and Adjustable Rate Mortgages Deserve Another Look
With today’s market, many variable and adjustable-rate mortgages are offering sizeable discounts from Prime.
While these products aren’t the right fit for everyone, they do offer one feature many homeowners appreciate:
The penalty to break a standard variable or adjustable-rate mortgage is typically just three months’ interest.
That means if circumstances change during your term, the cost of making a change is often much lower than it would be with many discounted fixed-rate mortgages.
Variable-rate mortgages aren’t simply about chasing rates—they can provide valuable flexibility when life doesn’t follow the original plan.
Don’t Shop for a Rate—Shop for the Right Mortgage
I think one of the most amazing things about being a mortgage broker is, that, as much as we try to stay in-touch with our clients through email, phone, text, newsletter, blog, podcast, and social media, we still find that clients have made significant changes to their mortgages without letting us know and have incurred penalties.
It’s easy to save a few dollars each month by choosing the absolute lowest advertised mortgage rate.
But here’s the question every borrower should ask:
Why would you save a minimal amount today if there’s a good chance you could pay a HUGE mortgage penalty should you need to make changes mid-term?
The best mortgage isn’t always the one with the lowest interest rate.
It’s the one that fits your financial goals, your future plans, and gives you the flexibility you may need if life throws you a curveball.
Let’s Look Beyond the Rate
At Mainstream Mortgages, we take the time to explain not only the interest rate, but also the mortgage features, prepayment privileges, portability, lender policies, and potential penalties before you sign.
Whether you’re buying your first home, renewing your mortgage, refinancing, or simply wondering if your current mortgage is still the right fit, we’re here to help you make an informed decision.
If you’re a Realtor®, financial professional, or industry partner, we’d also be happy to work together to help clients understand the true cost of mortgage financing—not just the advertised rate.
Because the smartest mortgage decision isn’t always the cheapest rate.
It’s the mortgage that protects your future.
