Blog > Should You Break Your Mortgage to Get a Lower Rate? | Mortgage Tips for Canadians
If you’ve found yourself thinking, “Mortgage rates seem more manageable than they were a year or two ago — should I break my mortgage to save?” you’re not alone. Many Canadian homeowners (especially first-time buyers) are watching rate movements closely and wondering if now is the time to make a switch. But before you pick up the phone and call your lender, let’s break down what it really means to break your mortgage — and how to decide if it’s worth it for your situation.
This is different than if your mortgage is up for renewal in 2026. If that is the case, check out my tips for mortgage renewal here.
Okay, back to the main question, “should you break your mortgage to get a lower rate?”
What Does “Breaking Your Mortgage” Mean?
When you get a mortgage in Canada, you agree to a term — most commonly 3 or 5 years. You can’t just switch lenders or change your interest rate whenever you feel like it without consequences. Renegotiating your mortgage before the term ends is called breaking your mortgage, and it usually comes with a prepayment penalty or “breakage cost.”
If you have an open mortgage, you can pay it off early without penalty — but most Canadian mortgages are closed. With a closed mortgage, you’ll owe a penalty that can be costly.
What Kind of Penalties Are We Talking About?
The amount you’ll pay depends on your rate type:
- Variable rate mortgages: Usually just three months’ interest as a penalty — pretty straightforward.
- Fixed rate mortgages: The penalty is often more complex — the lender compares your current rate to today’s rates using something called Interest Rate Differential (IRD). You’ll pay whichever is higher — three months’ interest or the IRD — and that can add up fast.
Because IRD calculations vary by lender, the same scenario with two lenders can produce very different penalty amounts.
👉 Pro tip: Always call your lender and ask for a written penalty quote — that’s the actual number you’ll need for your math.
Why You Might Think Breaking Makes Sense
Lower rates mean lower monthly payments and less interest over the long haul. That sounds great — but the key question is:
Will the savings from the lower rate outweigh the cost of the penalty?
This is where the idea of a break-even point becomes crucial.
What Is a Break-Even Point?
Your break-even point is how long it takes for the savings from your new, lower mortgage rate to offset the penalty and any costs of switching. For example: if switching saves you $300 per month but costs $6,000 in penalties and fees, it would take about 20 months just to break even.
Want to see if switching rates actually saves you money? Try Dominion Lending Centres’ mortgage toolbox app to estimate total interest saved compared to your current mortgage — and then plug those numbers into a break-even calculator to see how long it takes to recover any penalties and costs before you switch.
If you plan to live in the home longer than that — it could be worth it. If not, you might be better off staying put until your mortgage term naturally ends.
First-Time Homebuyer Mistakes to Avoid
Breaking a mortgage is not just about the interest rate — it’s about the total cost and timing. A few common mistakes among first-time buyers:
- Focusing only on the rate. Lower rates are great, but if penalties are huge, your total cost can still be higher.
- Not calculating the break-even point. Without the math, you’re guessing.
- Not exploring other options first. Many lenders offer flexibility — like blend-and-extend or porting your mortgage — that can help you get a lower rate without a big penalty.
Alternatives to Breaking Your Mortgage
Before you pull the plug on your current contract, consider these options:
- Port your mortgage if you’re buying a new home — you take your rate with you and avoid penalties.
- Blend and extend — a lender might blend your old rate with the new one and extend your term with no penalty.
- Renew early with your current lender — sometimes they’ll offer a competitive rate without charging a break fee.
- Make use of prepayment privileges — any extra principal you’ve paid reduces your balance and, in turn, your penalty if you do break.
So, Should You Break Your Mortgage?
There’s no one-size-fits-all answer — but here’s a simple decision-making framework:
- Find out your exact penalty. (Call your lender!)
- Estimate your new rate and payment with a different lender.
- Calculate your break-even point.
- Compare it to how long you plan to stay in the home.
- Factor in stress, market uncertainty, and future rate changes.
If the break-even point is shorter than your stay and the math works in your favor, it might be worth it. If not, riding out your term or exploring alternatives could save you thousands.
