Mortgage Penalties in Canada: Complete Guide to Breaking Your Mortgage - Mortgage Tips blog post featured image

Breaking your mortgage early is one of the most expensive mistakes Canadians make—often costing $10,000 to $30,000 or more. Understanding how penalties work before you sign could save you a small fortune.


How Mortgage Penalties Work

When you break a fixed-rate mortgage before its term ends, you pay a penalty to compensate the lender for lost interest income.

The Two Penalty Calculations

Lenders use the higher of:

  1. Three months' interest - Simple calculation based on your current rate
  2. Interest Rate Differential (IRD) - Complex calculation that's often much higher
Calculation Formula Typical Amount
3 months' interest Balance × Rate × 3/12 $3,000 - $6,000
IRD Balance × Rate Difference × Remaining Term $10,000 - $40,000+

Interest Rate Differential Explained

IRD compensates the lender for the difference between your rate and current rates:

Example Calculation:

  • Original rate: 5.00%
  • Current rate for remaining term: 3.50%
  • Difference: 1.50%
  • Remaining balance: $400,000
  • Time remaining: 3 years

IRD Penalty: $400,000 × 1.50% × 3 = $18,000

Why IRD Varies So Much

Different lenders calculate IRD differently:

Lender Type IRD Calculation Penalty Level
Big banks Posted rate vs current posted Highest
Credit unions Contract rate vs current Medium
Monolines Contract rate vs current Lowest

Critical insight: A mortgage with a big bank could have an IRD penalty 3-4× higher than the same mortgage with a monoline lender.

Variable Rate Penalties

Variable rate mortgages typically have much lower penalties:

Rate Type Penalty Example ($400K balance, 5% rate)
Variable 3 months' interest only $5,000
Fixed IRD (if higher) $15,000 - $30,000

Strategy: If you think you might break early, variable rate flexibility can be worth the potential rate premium.


Common Reasons for Breaking Mortgages

Life Events

  • Divorce or separation
  • Job relocation
  • Growing family needs more space
  • Downsizing after kids leave
  • Financial hardship

Financial Opportunities

  • Rates drop significantly
  • Debt consolidation makes sense
  • Accessing home equity
  • Investment opportunities

When Breaking Makes Sense

Calculate the math:

Factor Amount
Penalty cost $15,000
Rate savings over 5 years $25,000
Net benefit $10,000

Breaking makes sense when savings exceed costs. Our team can run this analysis for you.


Strategies to Minimize Penalties

1. Port Your Mortgage

If you're moving, you may be able to transfer your mortgage to the new property without penalty.

Porting requirements:

  • Must qualify at new property
  • Typically 30-120 day window
  • May be able to increase mortgage amount

2. Blend and Extend

Instead of breaking, blend your current rate with a new rate for an extended term.

Best for: Accessing additional funds while avoiding penalty

3. Wait It Out

If you're within 6-12 months of renewal, waiting may save thousands.

Calculate: Penalty cost vs. interest cost of waiting

4. Choose Flexible Products Initially

  • Variable rate mortgages (3 months' penalty)
  • Open mortgages (no penalty, higher rate)
  • Shorter terms (less time to break)

Lender Comparison: Penalty Policies

Lender Type Penalty Fairness Notes
Big 5 Banks Lower Use posted rate for IRD
Credit Unions Medium-Fair Often use contract rate
Monoline Lenders Fairest Contract rate, transparent
Private Lenders Varies Read contract carefully

What to Ask Before Signing

  1. How is the IRD calculated?
  2. What rates are used (posted vs. contract)?
  3. Can I port to a new property?
  4. Is blend-and-extend available?
  5. What are the maximum prepayment privileges?

FAQ

Q: Can I negotiate my penalty?
A: Sometimes. If refinancing with the same lender or in financial hardship, some lenders will reduce or waive penalties.

Q: Is the penalty tax-deductible?
A: Not for your primary residence. For rental properties, penalties may be deductible as a financing cost.

Q: What if I sell my home and buy another?
A: You may be able to port your mortgage to avoid the penalty. Timing and qualification rules apply.

Q: How do I find out my exact penalty?
A: Contact your lender directly for a penalty quote. They're required to provide this information.

Q: Are there mortgages with no penalties?
A: Open mortgages have no penalties but charge higher rates. Some lenders offer "no-frills" products with reduced penalties.
