Is Refinancing Right for You?

Refinancing your Ontario mortgage can provide significant financial benefits, but it's not always the right move. Breaking your current mortgage comes with costs, and understanding when the math works in your favor is essential for making a smart decision.

This guide helps you evaluate whether refinancing makes sense for your specific situation.

Common Reasons to Refinance

Ontario homeowners typically refinance for one of these reasons:

1. Securing a Lower Interest Rate

If rates have dropped significantly since you got your mortgage, refinancing could save thousands over your remaining term. The key question is whether savings exceed the costs of breaking your current mortgage.

2. Accessing Home Equity

Refinancing allows you to borrow against your home's increased value. Common uses include:

  • Home renovations
  • Debt consolidation
  • Investment property down payment
  • Business investment
  • Education expenses

3. Consolidating Debt

Replacing high-interest debt (credit cards at 19-29%) with a low mortgage rate can save substantial interest and simplify payments into one monthly amount.

4. Changing Mortgage Terms

Refinancing lets you switch from variable to fixed (or vice versa), adjust your amortization, or modify other terms that no longer suit your needs.

Understanding Refinancing Costs

Before deciding to refinance, calculate all associated costs:

Mortgage Prepayment Penalty

This is usually the largest cost and varies by mortgage type:

Variable rate mortgages: Typically 3 months' interest

  • Example: $500,000 balance at 5.5% = ~$6,875 penalty

Fixed rate mortgages: Greater of 3 months' interest OR Interest Rate Differential (IRD)

  • IRD can be substantial, sometimes $15,000-$30,000+ on larger mortgages
  • Calculation method varies by lender (some more favorable than others)

Other Refinancing Costs

  • Legal fees: $800 - $1,500
  • Appraisal: $300 - $500
  • Discharge fee: $200 - $400
  • Title insurance: $250 - $400
  • Registration fees: $50 - $100

Total Refinancing Cost Example

Variable rate refinance:
Penalty: $6,875
Legal fees: $1,200
Appraisal: $400
Other fees: $500
Total: ~$8,975

The Break-Even Calculation

The key question: How long until your savings exceed your costs?

Break-Even Formula

Break-Even (months) = Total Refinancing Costs ÷ Monthly Savings

Example Calculation

Current situation:

  • Mortgage balance: $450,000
  • Current rate: 5.75%
  • Monthly payment: $2,847
  • Remaining term: 3 years

Refinance option:

  • New rate: 4.75%
  • New monthly payment: $2,542
  • Monthly savings: $305

Costs:

  • Penalty (IRD): $12,000
  • Other fees: $2,000
  • Total: $14,000

Break-even: $14,000 ÷ $305 = 46 months (3.8 years)

In this example, refinancing only makes sense if you plan to stay in the home for at least 4 years.

When Refinancing Makes Sense

Consider refinancing when:

Rate Drop Exceeds 1%

As a general rule, a rate reduction of at least 1% is typically needed to offset refinancing costs, especially with fixed-rate mortgages.

Variable Rate Mortgage

The 3-month interest penalty on variable rates makes refinancing more attractive. A 0.5% rate drop might justify refinancing with a variable mortgage.

Approaching Renewal

If you're within 4-6 months of renewal, penalties are minimal and refinancing costs are low. Many lenders allow early renewal with reduced or waived penalties.

Significant Equity Access Needed

When accessing equity for high-value purposes (investment, debt consolidation with significant savings), the long-term benefits may outweigh refinancing costs.

Long Time Remaining

More time remaining means more months to recoup costs through savings. Refinancing early in a 5-year term is riskier than later.

When to Avoid Refinancing

Refinancing may not make sense when:

High Penalty Relative to Savings

If your IRD penalty is very high (common with discounted fixed rates from major banks), the break-even period may be too long.

Short Time Remaining

With less than 2 years remaining on your term, waiting for renewal is often smarter than paying penalties.

Plans to Sell Soon

If you might sell within 3 years, refinancing costs may not be recovered. Portable mortgages offer flexibility if selling is possible.

Minimal Rate Improvement

A 0.25-0.50% rate drop rarely justifies the costs and hassle of refinancing, especially with fixed-rate penalties.

Refinancing for Debt Consolidation

Using refinancing to consolidate high-interest debt requires careful analysis:

Potential Savings Example

Current debt:

  • Credit cards: $25,000 at 19.99% = $416/month interest
  • Car loan: $15,000 at 7.99% = $100/month interest
  • Line of credit: $10,000 at 8.99% = $75/month interest
  • Total monthly interest: $591

Refinanced at 4.99%:

  • Additional $50,000 on mortgage = $208/month interest
  • Monthly savings: $383

Important Considerations

  • You're converting unsecured debt to secured (your home is at risk)
  • Extended amortization means paying interest longer
  • Discipline needed to avoid accumulating new debt
  • Total interest over time may be higher despite lower rate

Refinancing vs. Second Mortgage

Sometimes a second mortgage or HELOC makes more sense than refinancing:

Consider a Second Mortgage When:

  • Your first mortgage has a favorable rate you don't want to lose
  • Prepayment penalty would be very high
  • You need less than 20% of your equity
  • You want to keep first mortgage terms intact

Consider Refinancing When:

  • Your current rate is higher than available rates
  • Penalty is manageable (variable rate or near renewal)
  • You want to restructure the entire mortgage
  • You're accessing significant equity

  2. Request penalty quote: Ask your current lender for exact penalty calculation
  3. Shop for new rates: Compare options from multiple lenders
  4. Calculate break-even: Ensure savings justify costs
