When to Refinance Your Mortgage in Ontario: 7 Situations Where It Actually Makes Sense
Refinancing your mortgage means breaking your existing mortgage and replacing it with a new one — different rate, different term, different amount, or all three. Done right, it can save you tens of thousands. Done wrong, it costs a penalty and gains nothing.
Here's an honest breakdown of when refinancing makes sense in Ontario, and when it doesn't.
What Does Refinancing Cost?
Before evaluating whether to refinance, you need to know what it costs to break your current mortgage:
| Mortgage Type | Penalty | Typical Amount |
|---|---|---|
| Variable rate | 3 months interest | $3,000–$8,000 |
| Fixed rate (monoline/credit union) | Greater of 3 months interest or IRD | $2,000–$15,000 |
| Fixed rate (big 5 bank) | Greater of 3 months interest or IRD (inflated formula) | $10,000–$40,000+ |
⚠️ Big bank IRD calculations use a posted rate comparison that significantly inflates the penalty. A $500,000 fixed mortgage at a big bank with 3 years remaining can carry a $25,000–$40,000 break penalty. Call your lender to get the exact penalty before making any decisions.
The Breakeven Calculation
The only number that matters when considering a mid-term refinance:
Months to break even = Penalty ÷ Monthly savings from lower rate
Example: $12,000 penalty ÷ $400/month savings = 30 months. If you plan to stay in the home (and keep the mortgage) for more than 30 months, refinancing makes financial sense. If you're selling in 18 months, it doesn't.
7 Situations Where Refinancing Makes Sense
1. Rates Have Dropped Significantly
If your current rate is 6.5% and you can refinance to 5.0%, the savings can easily exceed the penalty — especially on larger balances and longer remaining terms. Run the breakeven calculation before deciding.
2. Debt Consolidation
You're carrying high-interest debt (credit cards at 20%, car loans at 9%) and have available equity. Rolling $60,000 in consumer debt into your mortgage at 6% frees up $1,000+/month in cash flow. Even with a penalty, the math usually works. See our debt consolidation guide.
3. Accessing Equity for a Major Need
Home renovation, tuition, investing in another property, starting a business. If your property has appreciated and you need capital, a refinance lets you access up to 80% LTV at mortgage rates — significantly cheaper than personal loans or lines of credit.
4. Removing a Name from the Mortgage
Separation, divorce, or buying out a co-owner. You need to refinance to remove the departing party from the mortgage — the lender requires the remaining owner to qualify independently for the full amount.
5. Switching from Variable to Fixed (or Vice Versa)
If you're in a variable rate and rates are rising faster than expected, breaking to lock into a fixed rate can provide certainty. Alternatively, if you're in a fixed rate near the peak and rates are falling, moving to variable could save money — but only if your remaining term is short or the penalty is small.
6. Private Mortgage Exit
You took a private mortgage at 10–12% to solve a problem (power of sale, poor credit, income gap). Your situation has improved. Refinancing into an A or B-lender product is the natural exit strategy. This is planned from day one with a good broker.
7. Changing Amortization
Your income has dropped and you need lower payments — extending the amortization from 20 to 25 years reduces monthly payments significantly. Or the reverse: income has grown and you want to accelerate payoff by shortening the amortization.
💡 Near your renewal date? If you're within 4 months of renewal, don't break your mortgage — wait for renewal and accomplish the same goals (rate change, equity access, debt consolidation) with no penalty at all.
When Refinancing Doesn't Make Sense
- You're selling within 12–18 months (penalty won't be recovered)
- The rate difference is less than 0.50% (savings too small)
- You're in a big bank fixed mortgage with 3+ years remaining (IRD penalty likely too high)
- Your renewal date is within 4 months (just wait)
- You want to access equity but haven't compared second mortgage vs. refinance costs

How do I calculate if refinancing is worth it?
Calculate your break penalty (call your lender for the exact number). Then calculate monthly savings from the new rate. Divide penalty by monthly savings = breakeven in months. If you'll keep the mortgage longer than that, refinancing makes sense.
What is the penalty for breaking a fixed mortgage?
The greater of 3 months interest or the Interest Rate Differential (IRD). Big banks use an inflated IRD formula — $10,000–$40,000 is common on a $500K fixed mortgage. Monolines and credit unions are typically much lower. Always get the exact amount from your lender before deciding.
Can I refinance if my mortgage is with a private lender?
Yes — and this is usually the goal. Private mortgages are short-term. The exit strategy is refinancing into a B or A-lender product as your credit or income situation improves. A good broker builds this exit plan from day one.
